We are merging two Active Directories to one and Exchange 2003 was one the components that needed to be migrated to the new Active Directory. The old Exchange 2003 had Email addresses based on the login credentials of the users. In the new Active Directory user login credentials differ from the local part of the email address. So user name and email address where no longer related.

The problem we ran into was that when logging on to your Exchange account, using IMAP or POP3, you need to supply your user credentials and the alias that is connected your account. Your login looks something like this: AD\Username\Alias. If you try to logon with just your username you get the error USER UNKNOWN.

Thanks to my colleague Arno Beverwijk for reading the documentation…

So we made the Alias match the userlogonname so we didn’t have to bother our users with special logon procedures.

A real case of RTFM…….. It’s not a BUG it’s a FEAUTURE.
