Outlook add-in not showing after installation

Occasional Visitor



I have installed the CalDavSynchronizer add-in but have issues getting it running. Installation is successful and as far as I can tell from the registry entries it is installed, but it does not even show up under File, Options, Add-Ins.


My versions are:


Windows: 10.0.22621 Build 22621
Outlook: 2210 (Build 15726.20174 Microsoft Store)
CalDav Synchronizer: 4.3.0


Any advice on how I can debug why a certain add-in is not working?


Thanks for your support, regards, Robert
