Moin,
nettania Currently I ask them not to shut down the computer in the evening
Thats because they loose the calendars on close right? Until the next windows update 😛.
nettania If I give the user access rights to another account, in the grommunio backend, than the calendars do not disappear.
you mean full rights/delegates on the whole mailbox?
crpb Hope the picture says enough.
That method above in the screenshot is also ok to use with only rights to a calendar/contacts/a couple folders.. so why not use it?
I know, it's more work but there currently seem to be some problems with the way you let the users add the shared calendars.
Just write them a "guide"(basically 3-4 screenshots..) how to add them in the account-settings (which are user settings so no admin stuff) or did you somehow prevent the editing of that with a gpo? Don't know if thats even possible on that level...
