Restricting a mailbox so that it can only receive mail from certain people/groups

A customer asked me about the Conference Room post I made a few days back… and wondered if it is possible to restrict who can book a resource like this.

It is…

having a look at the set-mailbox documentation on Technet here:, you will see embedded in there amongst a load of optional parameters one called ‘-AcceptMessagesOnlyFromDLMembers’

This is how you use it, when logged onto PowerShell server-side:

set-mailbox confroom -AcceptMessagesOnlyFromDLMembers allstaff

where in my case, confroom is the mailbox name for the resource I want to set permissions for, and allstaff is the name of the Distribution Group I want to grant access to.

If instead you wanted to just manage permissions for individual mailboxes, you would use AcceptMessagesOnlyFrom:

          set-mailbox confroom -AcceptMessagesOnlyFromDLMembers jonnyc
