Update
We found a timeout issue in the protocol towards specific versions of Exchange servers
This appeared to be the biggest remaining issue in the Exchange integration.

Identified
We identified different smaller issues with the Exchange synchronization.
We added additional logging and moved the synchronization to a completely separate server.
With that, we identified a couple of issues that made the synchronization fail.
One of these issues concerns "recurring events", so we had to disable synchronization of "recurring events" for now.
For most users, the other issues should be resolved and the synchronization is running automatically again.
We are looking into the remaining issues, but because of the better logging, we should be able to resolve these quicker.
The "recurring events" issue is also under further investigation.

Investigating
The syncing problem is narrowed down to only a handful of users.
Automatic synchronization is therefore disabled to be able to investigate those issues more thoroughly.
Manual synchronization of your calendar (with the syncing button on your calendar) should be possible.
In case of a problem, feel free to contact our support desk.
