Under Exchange 2007, can a single Active Directory user have multiple unique mailboxes? When attempting to create a second mailbox for a given user, that user is no longer in the list of choose-able ones, since they already have a first mailbox.
I'm aware that a single mailbox can have multiple SMTP addresses associated with it, but the downfall I'm running into is when creating a new Distribution Group. It seems you can only associate users with a Distribution Group, but I want to send to a particular email address, which is often not the default reply for that user.
In our current non-Exchange IMAP setup, each email address is its own mailbox, and some users have several. Aliases (distribution groups, effectively) become straightforward, as messages can be delivered to a specific set of email addresses.
Am I doing something wrong, or just approaching this the wrong way? I could make a new Active Directory account & Mailbox combo for each address I wish to catch, but that seems like the wrong thing to do. I'm really new to Exchange, so any hints are much appreciated.
