We receintly changed our username format, from first name and first initial of last name, to first initial of first name and last name. Example: old: dana, new: dandries
It worked fine for everyone in the company except 1 person. For this person, when I have the old email format, I get the following error message from my exchange server.
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##
When I take out her alias email (old format), I don't get that error message anymore?
Also, My exchange 2003 is set as the master in hte 2003 ESM, how do I change that to the 2007 exchange to be the master?
