Hi everybody!
I have a strange problem. Outlook 2013 stops receiving emails if the CalDavSynchronizer AddIn is activated. If it is deactivated, everything works fine. If it is activated, i have to click "Send/Received Emails" on my own every time. Automatic send/receive doesn't work anymore. I installed it on a lot of workstations (around 20) and only 2 have this problem. I also reinstalled windows and tried a fresh installation, but it didn't work.

I tested a lot of old versions to find the root of the bug. The last version of CalDavSynchronizer without this problem was V2.1.3 and the first version with this bug is V2.2.0. In the commit history, there is a commit message "Add general option to trigger sync after Outlook Send/Receive finishes, github issue 141." between these two versions. Maybe something is buggy with this?

1) Windows Version
   Windows 7 Professional x64 SP1

2) Outlook Version
   Outlook 2013

3) CalDavSynchronizer Version
   3.1

4) CalDav/Cardav Server and Version
   NextCloud 12.0.5

Btw: Thank you very much for this wonderful software! I like it very much!
