2003 to 2010 transition, remove undeleted 2003 mailboxes?
Posted on 2010-08-24
I am at the last stages of a 2003 to 2010 exchange transition. All the mailboxes, public folders, etc have been moved to 2010. Address books have been updated and moved. The new server is authoritative for everything.
The public folder heirarchy has been moved to 2010 as well, and as there was no more messages to pass between the two environments, the 2003-2010 routing group connectors have been removed, and the recipient update service for 2003 has been deleted.
As I understand it, to properly remove 2003 I should uninstall it via add-remove next. I am not able to do that because Exchange thinks there are still some mailboxes on the 2003 storage group. These mailboxes were created successfully on the 2010 server during the transition but not all of them were auto-deleted.
I've attempted to dismount the store and remove the files but that it thinks there is still a mailbox on the store. If I try to purge the mailbox it tells me its already been reconnected...
Could anyone please clarify what I need to do for these junk mailbox files?
