same problem with the “exe” process in Ubuntu 21.04, 21.10 and 22.04 on my side.
For users not knowing how to kill those processes and identifing the problem themself, not me :), the DeskApp is not recommended in any way.
The calendar integration is quite a pain, and has always been, but that is independent from the groupware;
I can’t agree.
Calendar, Contacts, Tasks, Notes, etc., and audio/video private calls are all part of the groupware solution/appliance.
And I don’t like Microsoft, but ActiveSync is a good tech inventment and it does all that on-the-fly.
And when re-installing my system I simply copy my home folder over and all settings and content are migrated.
And when I reinstall my systems (no matter of the type of the device), i don’t even have to copy anything from any folder to a new device.
I just install client TLS certificate for mutual authentication, and everything is synced in practicably no time.
DeskApp primarily depends on the version of WebApp installed on the server. Using a modern WebApp could work, but is not actively tested (there may be features in the newer WebApp that don’t work with Zarafa like scheduling out of office for a time in the future).
