I'm setting up my first Exchange server, which will import ~150 mailboxes from an offsite IMAP server. Obviously, I'd like to create these accounts en masse, but the creation process isn't straightforward as it seems.
I can select multiple accounts via Exchange Management Tools, and create all of them simultaneously, however, they all create address resembling firstname.lastname@example.org.
They need to be email@example.com
For example, John smith appears as firstname.lastname@example.org - I need email@example.com
Hopefully this doesn't require too much scripting?
