Hi
The ARM service account has full access permissions on exchange database level but can't change permissions on user mailboxes. Shared mailbox etc are working fine.
When trying to open a user mailbox from the list (in Ressources -> Exchange), right click -> change permissions, it actually jumps to the root @ 'Exchange -> Servername -> Mailboxes' and no permissions are being displayed.
Same with 'search'. The search finds the user mailboxes but when trying to open it, it jumps to the root again, not to the user's mailbox itself.
Any idea what causes this behavior?
