Agreed with Amer, I'm having the same result, and changing the second UID FETCH seems to fix the problems.
This doesn't seem to work when initiating from the command line, but adding NoDisplay=false to ~/.config/autostart/davmail.desktop removes the icon on startup. (Unfortunately, changing /usr/share/applications/davmail.desktop doesn't seem to do anything whether it's started from the command line or not.) So that sort of resolves the issue - but maybe this could be added as an option? Much appreciated!

Wonderful! Great job figuring this out so quickly - thanks very much!
