I personally suspect something didn't get deleted correctly but I can not seem to find anything related to ' in ADSI Edit or via 'Get-Mailbox' So it appears all traces of it are deleted/removed but some how some way Exchange is holding a ghost somewhere! (This way we can just add users to a group in AD-OU and have it forward to everyone in that group) - They were having issues keeping track of the actual 'Shared mailbox' so wanted it setup like this. My associate deleted the 'Shared mailbox' and then created the group via the Exchange Management Console. We have several distribution groups all working just fine, the only difference with this group is 'It was a SHARED MAILBOX' prior.
