For those that are waiting for a new version. It is almost there.
I am waiting for the latest translation update and there is one bug which needs fixing before I want to release.
The title of the add-on is changed to reflect the newly supported functionality like:
- Exchange 2013 server support (partially tested main is working)
- Search access to the Global Address List of the Exchange server.
- Address autocompletion in creating new emails or adding attendees to an event.
- Almost full tasks support as far as the EWS protocol allows.
Have a look at the main page for more info.
