Question : Remove share permissions on user mailbox.

When looking at the Exchange Management Console I can see that one of our user's mailboxes is listed as being a "Shared Mailbox" in the column titled "Recipient Type Details".

I would find out who the mailbox is being shared with and then I would (probably) like to remove those share permissions.

My thoughts are that this is a carry over from our Exchange 2000 migration from many months ago.

I am fairly unfamiliar with the Power Shell but I can pick my way through it well enough to get along.

Thanks.

Answer : Remove share permissions on user mailbox.

Open an Exchange Management Shell and run
Set-Mailbox Name-of-Mailbox -Type Regular
And you should be sorted. (of course substitute 'Name-of-Mailbox with then name of the mailbox you want to convert)
