Greetings, During an Exchange 2003 migration at a startup I was previously working for , I had an issue with several accounts that were on a Exchange 5.5 server that had multiple mailboxes associated with the same user account. To prepare for Exchange 2003, I created new user accounts ( user1, user 2, etc ) and associated the accounts with the mailboxes that had the same user account mapped to it, so that they would have a one to one mapping. I installed the AD connector for Exchange 2003, when I went through the AD list after replication occurred it renamed several of the accounts. I corrected the names, and ran AD synchronization. I then exported all the mail in the mailboxes that I created the one to one mappings for into PST files and delete the five mailboxes that were no longer needed. Several minutes after replication occurred the accounts that were associate with multiple mailboxes also were deleted. Can anyone explain why this could have occurred? Could this have been related to SID history issue? Could this be related to the Cisco Unity Connector or the Blackberry Enterprise server connector adding additional hooks into the mailboxes? Has any one else experienced this?
