Deactivate user main email address

[JohnnMZ]

Hello,

An organisation I work for wants all employees to use shared mailboxes. There's a lot of staff turnover and they want to be able to easily ensure business continuity by reassigning the shared mailbox to new arrivals.

Users therefore end up with two mailboxes: their personal mailbox and the shared mailbox.

I'm afraid they'll use both boxes at the same time and I'd like to be able to disable the use of the personal email address and keep only the shared box.

Is there a solution for this?

Thank you in advance,

John

No, as shared mailboxes cannot be accessed directly - you need the user's own account active. You can use mail flow rules from preventing from sending/receiving messages, if that's what you are after.

You may consider to restrict access on personal mailboxes by disabling certain protocols like POP, IMAP, ActiveSync, or OWA in the Exchange admin center
