I'm attempting to lower the number of email accounts on our SBS 2003 Exchange. One of our users has enjoyed the luxury of 2 email accounts for sometime. Dept@coname.com and Name@coname.com, for example. She signs in as Dept@coname but receives email at both addresses. The AD User Record of Dept@coname had full access to the mailbox rights of User@coname and vice versa. I wanted to turn these 2 into one, and I thought the procedure would be simple. In the exchange system manager, I delete the empty mailbox of User@coname, then purged it. The in AD Users I open Dept@Coname and included User@coname on the list of smtp email-addresses. However, now anyone sending from Outlook (internally at least) to User@coname.com, is getting "Your message did not reach some or all of the intended recipients" Even after I tried to force an update of the offline address list, then manually trigger a download of the address book for Outlook 2010, when I began to enter User@, the To: field cache fills in User@coname.com and right clicking it to display phone book properties attempts to display the former, now deleted, mailbox info of user@coname, And I get the undeliverable message error after as well. Any suggestions for correcting this? One suggesting put the User@coname in the contact list, but if Outlook is going to continue to insist on using cache data, this will be of no use either.

You can add the old legacyExchangeDN name from the user@coname as a custom X500 address to the dept@coname user. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
