Migrate to 2010 Exchange, Distribution groups wrong.
Posted on 2010-08-16
We recently migrated over about 500 mailboxes to Exchange 2010 from another domain.
Some of the users have set up their own distribution lists on the old exchange server. While they were brought over, any internal names are still trying to access the mailboxes by the name of their location in the old exchange server.
Is there any way to automate updating these lists? I am sure we could just delete and recreate, or even export, fix, import, but both of these would take days with all these users.
Thanks for any suggestions.
