Exchange EWS Provider Add-on for Lightning (Thunderbird/Seamonkey)

(2014-10-21) As you can read I no longer maintain this add-on. But the guys from Ericsson have taken over maintanance. You can get new versions from their github page: https://github.com/Ericsson/exchangecalendar/releases.

I will keep my pages online for the archive.

(2014-05-08) I do not maintain this add-on anymore. Anyone who would like to take over can use the source at Github for it’s own fork. Thanks to everyone who has supported and helped to get the add-on to it’s current state.

!!! The next information is old and outdated !!!


lightningexchangecalendarWelcome on the website with the only add-on for Thunderbird and Seamonkey which will add access to you Exchange calendars, contacts and Global Address List (GAL). It is an add-on for the Lightning Calendering Add-on and will allow you to communicate with an Exchange 2007, 2010 and 2013 server using the Exchange Web Service (EWS) interface.You can access any Calendar, Task or Contacts folder on the EWS server in an easy way. And also manage your “Out of Office” settings.

Requirements:

  • Version 3.2.x for Thunderbird 12 up to 27 (tested up to and with 27).
  • Version 3.1.x for Thunderbird 6 up to 17 (tested up to and with 17).
  • Version 3.0.x for Thunderbird 6 up to 17 (tested up to and with 17).
  • Version 2.x.x for Thunderbird 6 up to 14 (tested up to and with 14).
  • Seamonkey 2.6.1 – 2.20.
  • Lightning add-on
  • This add-on.
  • Access to an Exchange Webservice Server (EWS) with an username, password and/or primarySMTP or email alias.
  • The Exchange Webservice Server of Exchange 2007, 2010 or 2013. Or that from Microsoft Office 365 (see FAQ for howto).

The latest stable version (3.1.3 released 25th of October 2012), which can be newer than on the Mozilla repository, can also be downloaded from this site: [download id=”13″]. If you find problems please report them to the bugzilla. What has changed please see [download id=”14″].

The latest development version (3.2.x) can be downloaded through this link: [download id=”17″]. Because of it’s development nature some new functionality might only work half because it is still in development. Or it is a bug fix which is still in it’s testing phase. If you find problems please report them. See Reporting Bugs. What has changed please see [download id=”18″]. (On GitHUB this is the “master” branch).
Please try this version and turn on offline cache (below calendar settings). When you already use offline cache please turn it first off for the calendar. Restart TB and then turn it on again. It should stay in sync now.

All versions can be downloaded from the download page.

Changed in version 3.2.0-BetaX:

  • Completely new Event Interface. We now use our own which is an extension of the one default in Lightning.
  • New TimeZone function for matching between the Exchange TimeZone and the Lightning TimeZone.
  • Almost complete rewrite of task/todo handling.
  • It will now try to show the Exchange time zone for the start and end times as close as it can match it to the one in Lightning.
  • Added the Exchange SOAP Autodiscovery functionality. This will be used first and when it fails it will fall back to the old POX Autodiscovery.
  • Can follow redirectAddr response from Exchange.
  • Will try Basic authentication as default when available.
  • Fixed problems with opening attachments when having multiple items open.
  • Adjusted reminder configuration to what is possible in Exchange.
  • Address autocompletion for composing emails or adding attendees to calendar event.
  • Showing of icon/image for contact in address book.
  • Added Exchange Task details.
  • Fixed editing Out Of Office messages with HTML editor.
  • New Exchange server version detection.
  • Rich text description editing/viewing including link editing and following.

What can it do:

  • Support Exchange server 2007, 2010 and 2013 (Office365).
  • Sync Calendar, Task/Todo and Contact items from an EWS (Exchange) server.  Syncing is done on a user settable poll interval. It will track changes on the server and update the local memory cache.
  • Create, modify and delete calendar events and task/todo items. They will get synced immediately with the EWS server.
  • Contacts are currently read-only.
  • Search the Global Address List (GAL).
  • Use contacts and GAL in address auto completion.
  • During creation of a new calendar you can use the Exchange Autodiscover functionality (when enabled on the Exchange server) to find the right server and mailbox settings. Selecting the right folder is easy with the build-in folder browser.
  • You can access any Calendar, Task or Contacts folder on your EWS server as long as you have the right primarySMTP or alias email address and enough permissions for the used user.
  • Let it poll your inbox for meeting invitation request or cancellations. They will show up in your calendar.
  • Manage how meeting invitations or cancellations are automatically handled (responded to).
  • Add as many calendar objects as you wish and Lightning will allow.
  • Manage “Out of Office”settings for each calendar mailbox.
  • Import ICS files.
  • Export to ICS files. (Experimental: new since 1.8.0a4 not a full calendar yet only local memory cache)
  • Manage and view attachments.
  • Edit event/todo description with rich-text. Colours, fonts, links, etc…
  • User availability (Free/Busy) information.
  • Currently in Dutch (Nederlands), English, French (Français) (Thanks to Dominique Fillon) , Swedish, Japanese and German (Deutsch) (Thanks to Christian A. Meyer) localizations. When you would like to make a translation for your language please let me know .
  • Can work with Basic, Negotiate and Kerberos authentication. Please see this page for an explanation. No NTLMv1 or NTLMv2 on Linux.

Known issues:

  • When Thunderbird is started or a new Calendar is added it can take some time to load and cache the items from the EWS server. Be patient it will all be loaded. After it is loaded it is fast because it will work with an local temporary memorycache.
  • Because of the previous slowness. When you try to change, add or delete an item during loading this change might take some time to be synced to the EWS server.
  • And those mentioned in the bugzilla.
  • It is not possible to accept or decline assigned tasks. Microsoft does not provide the necessary API calls for this. Even OWA cannot do this. Only outlook.

For questions please send them to Ericsson but first read the FAQ section or have a look at the Forum pages.

If you think of a nice feature or functionality which currently is not available have a look at the feature request page.

If you find a bug in this add-on please report it at https://www.1st-setup.nl/bugzilla/.

    Ciao using (ThunderBird 9.0 + lightening 1.1 + your ADDon 3.7.2)
    when I connect to a calendar of one of my colleagues
    – If he gimme full access from OWA , I see all details meeting and it work properly.
    – If he gimme just free/busy from OWA I cannot access to minimal infos. (calendar totally blank);

    Any possibility to access just to free/busy in external/colleague calendars?
    thanks Cesare

    PS: merry Xmas.

    • admin says:

      The Free/Busy information will onyl show if the other is free or busy no further details. For that you need more privileges. The Free/Busy information is used when you create a new meetig request in your own calendar and intvite other people on the same exchange server. It will only help in finding a free slot.

  8. Seems to work great, but my tasks do not show up. Not a major show stopper, just something to nag about :-). Is there anything I may need to tweak to get the tasks to show?

    Warm regards,

    Bard

    • I take back what I wrote about tasks not displaying. I hadn’t read the FAQ properly and pointed my calendar to the wrong root folder. My bad entirely. So this is now officially a totally great and awesome plugin.

    The plugin looks promising; however, when I try to sync my calendar I get a -101 error. I used the Autodiscovery function to configure the plugin. I can read my mail just fine but it won’t let me set the Folderbase to my Calendar folder, it just sets it to the Public folders. Is there any way of fixing this?

    Also when I try to save a new entry I get a similar error message in the status bar. I also get the following error messages in the console:

    – Could not find jar manifest entry ‘chrome/en-GB.manifest’. Which probably explains the blank dialog that appears whenever I have an error getting my calendar events. I use “en-US” for my locale.

    • admin says:

      Mark,
      Which version are you using? Latest development version can be downloaded from the website.
      Did you enter something in the “Mailbox” field. If you leave it empty then you can only use and browse public folders.
      Autodiscovery does not always work. This depends on if your provider made it available and if they used the default values for it.
      Currently it supports the following locales “nl”, “en-US” and “fr-FR”. As you mention it is looking for “en-GB”. Are you sure you are using “en-US”. You can test this by starting thunderbird from the command line with the “-UILocale en-US” option (e.g.: thunderbird -UILocale en-US)
      Regards,
      Michel.

    Hi Michel,
    I’m using 1.7.12a6 with Lightning 1.1.1 and Thunderbird 9. When I tried to create a new event I got this message:

    Error: no element found
    Source File: https://mncsoftware\mfortner@ringnes.mncsoftware.com/EWS/Exchange.asmx
    Line: 1

    This makes me wonder if the configuration that I’m using is wrong.

    I’m not sure how this web service works, and whether or not it requires a password and not just a userid. The rest of the console is the actual SOAP envelope and the following error message:

    Error: An error occurred when writing to the calendar Work! Error code: MODIFICATION_FAILED. Description: [xpconnect wrapped (nsISupports, calIItemBase, calIEvent, calIInternalShallowCopy, nsIClassInfo)]

    I have the problem that no invitation emails are sent for events in an exchange calendar, might this be a problem of the plugin? For my other calendars emails are sent out.

    Also, is there a way to show how created a certain event? We are using a shared calendar at work and that would be very helpful.

    I’m using Mozilla 9.0.1 and the 1.7.12 version of the plugin.

    • admin says:

      For the emails not send part. Is the calendar a calendar below the public folders? If so it is currently not possible to send out invitation requests. I’m working on this.

      I will put this in the feature request list. This information is available but Thunderbird/Lightning currently has no fields to show this info. I will have to create them.

      • Tobias says:

        Hey, thanks for the swift reply. The calendar is below the public folder. I’ll check for new updates to see when this is added.

    Hey there! Wondering when you will add support for “firstname.lastname” AD format? E.g. john.smith@exchange.com

    This is the error I receive:
    Title = [Javascript Application]
    Message = Error during checking of server:Warning during servercheck: responseCode: ErrorFolderNotFound
    msg: The specified folder could not be found in the store. and mailbox (-208)

    Thanks in advance, keep up the great work! 🙂

    • admin says:

      For which field to you mean the “firstname.lastname” AD format? Is it the mailbox field or the username. For the username it is available in version 1.7.12. For the mailbox it tries to detect the primarySMTP which belongs to the specified alias.

      When you think this is a bug. Please create a bug report in the buzilla.

  24. bring says:

    I’m not sure if this is a plugin or Exchange issue:

    When i accept an incoming meeting request and allow it to be placed in my exchange calender, the exchange server sees this as a new meeting with myself as the organizer, and starts sending out invitations to the other invitees. (instead of sending a accept message to the organizer)

    How can this behaviour be avoided, or what am i doing wrong?

  25. Brian says:

    Nice work. Wishlist: I have a bug for you but had some trouble with bugzilla account so here it is anyway:
    Create New Task popup: All fields work fine except “Reminder”. Setting a reminder date/time causes the following error connecting with Exchange 2010 server: –

    Envelope xmlns:s=”http://schemas.xmlsoap.org/soap/envelope/”>a:ErrorSchemaValidationThe request failed schema validation: The ‘http://schemas.microsoft.com/exchange/services/2006/types:ReminderDueBy’ element is invalid – The value ” is invalid according to its datatype ‘http://www.w3.org/2001/XMLSchema:dateTime’ – The string ” is not a valid XsdDateTime value.ErrorSchemaValidationThe request failed schema validation.2112The ‘http://schemas.microsoft.com/exchange/services/2006/types:ReminderDueBy’ element is invalid – The value ” is invalid according to its datatype ‘http://www.w3.org/2001/XMLSchema:dateTime’ – The string ” is not a valid XsdDateTime value.

    and then in a new popup

    Error Code: MODIFICATION FAILED
    Description [XPConnect wrapped (nsISupports, callItemBase, callToDo, callInternalShallowCopy, nsIClassInfo

    Looks like the date time string is messed up?

    • admin says:

      Brian,

      This problem was allready reported as a bug and has been fixed in the latest development version, 1.7.13ax.

      • Joan says:

        I had 2 problems with v. 1.7.12. One was this one, that if I tried to set up a repeating task to an Exchange 2010 server from Lightning, it would fail as above. The second was that repeating tasks set up through the Outlook Web App (OWA) would show up in Lightning, but when I marked a repeating task complete, the new due date was 4-5 hours ahead of schedule which made it the evening before it should be due. (E.g. “every Monday at 12:00 AM” would reset to the next Sunday at 7-8 PM.)

        I just upgraded to v. 1.7.13 and the first problem seems to be fixed, but the second remains. I set up a test task using Lightning for every Monday at 12:00 AM starting 3/5/12. It went to the Exchange 2010 server and ended up set at Sunday 3/4/12 7:00 PM even though the instructions still say “Occurs every Monday…”. I marked the first occurrence complete and now the next occurrence is 3/11/12 8 PM. I suspect the 7:00 vs. 8:00 PM when it should be the following midnight might be a clue to the problem: that’s our offset from Greenwich Mean Time, before and after Daylight Savings Time.

        I hope this can be fixed soon. The functionality is great otherwise.

  26. Nicholas says:

    Worked it out! (Thanks to the FAQ) Changed the authentication method to NTLM in Server Settings. Found a bug with Reminders and will post that shortly. Thanks! 🙂

    Hi All,

    I just wanted to let you know that while using the add-on your bandwidth usage may go up. My bandwidth increased over a Gb a day. I don’t think it’s a problem with the add-on itself but the amount of data being transfered.

    I’ve had to stop using it.

    Stacey

    • admin says:

      Stacey,

      Did you increase the polling intervals on the EWS settings page per calendar. By default they are every 3 seconds for the calendar and every 10 seconds for the inbox. Increase them and you bandwith usage should drop.

      Michel.

      • Stacey says:

        Hi again Michel,

        I’ve changed the settings, and all seems to be good now.

        checks once an hour now.

        As a suggestion, change the defaults to something reasonable…maybe a few minutes instead of seconds.

        Regards,
        Stacey

    Hello

    First off coming from the old Microsoft Exchange provider for Lightning this is definitly an improvement.

    However I am having some issues with Free/busy information. When accessing a calendar that I am allowed to view Free/Busy information for (this works through Outlook and Outlook Web Access just fine) I get a blank calendar.

    Do any special permissions need to be set on the calendar to view Free/Busy? We use the “Default” permission to allow people to view Free/Busy once authenticated.

    • admin says:

      To see Free/Busy information you need to type in the full email address of the person you are inviting. Only then it will show the info if you have the right permissions.
      Because the add-on has not yet access to the contacts/addresslist from exchange it cannot autofill the name while typing. So you have to enter the full email addres yourself.
      Hope this answers your question. It should work the same way as the old Exchange provider.

      Access to contacts/addresslist is on the todo list.

    Hi! What license is this released under? MPL? BSD? GPL? Is there source code available?

  33. Andy says:

    The addon works fine, I can see my Exchange Calender and make updates! I feel a bit sheepish, though, because I can’t figure out how to see an appointment’s details before accepting it. When I receive a meeting request as an email, all I see is an empty mail body and the three buttons for accepting, denying or saying “maybe”. What am I doing wrong?

    I can use “view page source” to see the raw data and figure out the time and date that I’ve been invited to, but there must be better way, somehow.

    • admin says:

      In the email view the Lightning add-on should display the invitation details. When you do not see them I do not know what is wrong. Ask on the Lightning chatgroup.
      In the calendar settings in OWA you can also specify to add new invitations to your calendar on receiving (done by the Exchange server). From there they will be visible and you are able to acknowledge them.

    Awesome addon, works fine on my Windoze 7 machine.
    However on my linux box it does not because of an authentication failure. It took a bit of digging around with various wget invocations to find out that ntlm authentication from any of my linux clients to the IIS 7 servers of my university is broken.
    On the other hand basic authentication works just fine. So is there a way to force the authentication method?

    Hi

    Very nice tool. I was even able to acces to access other persons released calenders, but there is one problem: Exchange publish private entries completly together with a private flag – so the entry is displayed with all details …

    Could you change this?

    • admin says:

      Please read Make an appointment or meeting private.
      I hope this answers your question.

      • Robert Magnus says:

        Hi

        Not completly. _Even_ if you set an appointment to private in Exchange, your addon list the appointment in full details. Afaik Exchange sends for private entries all datas plus an private flag, so the client is responsible for the “private” handling.

        regards, Robert

      • Rosario Carcò says:

        To my surprise you did not publish my comment. So I just made another test today and it shows that with your tool you CAN MODIFY even Appointments marked as private if you have Free/Busy (AvailabilitOnly) set on the standard user. THIS IS as security and PRIVACY issue that should be addressed either by Microsoft on the EWS side or on your code’s side.
        May I ask again: how could we intercept your EWS-Requests on our IIS so as to drop them or to filter out any private appointments before returning the data to your client?

        Thanks for your help, Rosario

        • admin says:

          Sometimes comments get lost in al the spam which the site receives. Sorry for that.
          As you mention the private flag is only a flag in exchange. The exchange server will always send all details of the calendar event even when the private flag is turned on. Probably the oulook and webmail clients of Microsoft are programmed to hide the data to the user but in the background they do receive it.
          I had more discussions about this. Currently there is one problem where the add-on is not able to detect if the calendar event is from the end user it self or that you are some one else who may view the calendar but we should hide private data from. Once I can determine this difference the add-on can hide at the right moment.
          Please do keep in memory that the data is still exchanged between the client and the servers as the server does send the data.

          • Rosario Carcò says:

            Thanks a lot. There seems to be a Microsoft EWS client that confirms all I have seen in my tests, and all you say above. So it should definitively be Microsoft who adjusts/fixes its EWS interface.

    1.8.11 works, so it would be interesting to try 1.8.12 – 1.8.17 to see where things broke.

    first of all the Addon works great. Do you have any plan to implement the contact synchronisation between Exchange 2010 and Thunderbird? At the moment i only can access the contacts with “Read-Only” rigths.

    Everything else is perfect.

    Best Regards
    Christian Heidemann

    PS: Sorry for my bad english

    There appears to be an issue with 1.8.19. I updated frp, 1.8.5 and after the update message filters were no longer working (greyed out) I removed 1.8.19 and re installed 1.8.5 and filters worked again.

      The problem with the grayed out filter options has been solved in latest development version 2.0.6

    I don’t see a possibility to access shared calenders of team mates which I’ve subscribed in outlook. Am I right?

    Thanks, Sven

    What modifications were made in dev versions 2.0.6 and 2.0.7?

    Can you guys take a look at bug 144? It really is a blocker for anyone that has repeating meetings without end dates that they’ve been invited to. The jobs just keep spinning and spinning and the network traffic is continuous to the point I’m worried that the MS Exchange Server guys are going to get upset.

    Thanks 🙂

    Hey there, I am having an issue with calendar invites to invents sent from my office 365 account. Lightning does not recognize them as calendar events and I have to open a browser to accept them, via the 365 web client. Once it is accepted, it will not sync to lightning. Anyone else having this issue?

    Great plugin! Thank you.

    I’ve got a problem with invitations.
    I’ve accepted an invitation, and in the second dialog changed to tentative.
    Now the invitation stays in the taskbar forever.
    How can I get rid of this? I already deleted the invitation-email from my mailfolders.

    Hi, thanks for a great plugin, without it I would be forced to use Outlook! Just wondering the progress on making this work with Thunderbird 15+ ?

    • admin says:

      I have a fix but because the change in 15 hits a lot of code in the add-on it will take some time.
      And I can only work on it in my spare/free time.

      It might take some weeks.
