Note: &nbsp;The steps in 316622 are incomplete. &nbsp;You must dismount the store before stopping ANY Exchange services. Otherwise, 316622 seems to solve all problems with the SystemMailbox user, especially if you applied/used 253784 which, I am sorry to say, bombed with me. &nbsp;Leave the Systemmailbox alone unless you want to spend some hours fixing the mess that can easily be made of it....

The systemmailbox user object in AD has been deleted. &nbsp;As such, the Mailbox Management Process has discovered this. &nbsp;The mailbox still exists and has been tombstoned and will be deleted in 27 days (and counting..).<br />
<br />
Does anyone know how to recover from this condition. &nbsp;<br />
<br />
That is, if I create a new user object called systemmailbox what additional tasks other than reconnecting the mailbox be?<br />
<br />
Cheers
