Just tested Outlook 2013 on a RDP server (non Cached) and with a user with two shared mailboxes assigned to them, one can be linked in ok via account settings>Add shared mailbox, when I tried to add the second shared mailbox I get a login prompt Tried manually linking shared mailbox into Outlook client via account settings, can then see mailbox but then get permission errors trying to access it. OWA access can link in shared mailbox and use and can even send as. Tried changing account mode to non-cached, still no access. Shared mailbox with this users full access rights assigned (and check in powershell) will NOT automatically show up in Outlook Client. Users own mailbox account linked in ok and working well. Test case user - brand new workstation with Win 10 pro. We are unable to remove the shared mailbox from that clients Outlook client.įrom OWA access works completely as expected.Ĭhecking permissions from powershell shows as expected full access as required.
These are already linked into a number of local users Outlook clients successfully however we are seeing permission issues causing some clients to be either unable to see a shared mailbox from within Outlook, or when removing Full access permissions, (these shared mailboxes were never standard mailboxes that have been converted either)
We have an Office 365 Tenancy with a number of Shared mailboxes. I have a number of users with similar issues to this.
