Using Exchange 2007 we have a mailbox that was named 'Engineering' with an email address of 'email@example.com'. They didn't want to see 'Engineering' in the 'To' field but rather 'Tech Support'. So I renamed mailbox to 'Tech Support' and sent a test email from my gmail account and all was fixed. But when I replied to that email in Outlook it said it was From 'Engineering'. If I double clicked on Engineering the email and display name all say 'Tech Support'. If I went ahead and sent the reply email to my gmail account, the 'From' would display 'Tech Support'. Just can't figure out how to change the FROM field when users here hit the reply button in Outlook. There's only 2 users that have access to that standalone mailbox. I've run adsiedit.msc and have found no traces of 'Engineering' anywhere. I've updated the offline address book. Is this cached somewhere that I'm missing?
