I have moved mailboxes from one store to another and now want to delete the old store. When I try to delete, I receive the error “one or more users currently use this mailbox store. These users must be moved…”
There are only three mailboxes present and they are system-related. SMTP with 0 items, System Attendant with 0 items and SystemMailbox with 401 items.
I was able to delete another store ealier in the week and did not run into this issue – but I’m having a hard time recalling if the SystemMailbox was present or if it was present but had no items – not sure if that matters.
I have run isinteg /fix and have moved the database files to a new location on the disk but the results are the same when trying to delete. When I view the advanced options in AD, I do not see any user accounts still tied to the message store in question.
I could use specific steps on how to delete this mailbox store from the storage group. Thanks.
