Currently it is possible to give permissions on the whole mailbox,

but not in the subfolders of the mailbox, e.g. "sent objects", "tasks" or "trash".

Since we have to check and also adjust the permissions of the mailboxes and subfolders during user creation or also during operation, this feature is very helpful.
It would be good if this is implemented in the ARM so that this is possible.
Maybe there is a way, but I haven't found it yet.
The support could not help us here either.
About a solution I would be very grateful
Many greetings
Sven
