mailbox move to EX2010 changes Primary smtp address
Posted on 2011-02-25
Im currently moving Exch2003 mailboxes to Exch2010. I’m experiencing the following issue:
In exchange 2003 I route multiple domain/name spaces; however, my primary name space is vitamins.com. If a user mailbox gets moved to ex2010 and they are using one of the secondary name spaces as their PRIMARY address (e.g. firstname.lastname@example.org) exchange changes their Primary address to email@example.com, the default namespace. How can I prevent exchange from changing their primary address?
