As IT for our small co. We decided to use SBS2003 to upgrade our operations. I found that after initial setup Exchange 2003 was working but using the 'wrong' "@company.com" tag on outgoing emails. During the course of trying to correct this I found several other items that wern't working right so I've disabled the SMTP and POP3 connectors, (I think) until I can figure out how to resurect exchange as our primary mail, contacts and calendar tool. I'm looking for the best, fastest, cleanest way to either scrub what's there or repair/rebuild exchange 2003 to work like it should. Any particular 'Exchange for Dummies' publication or Online lab or web event that I can look up would help. Thanks!

There are many, many, many Exchange books and articles in circulation. You said you used SBS to upgrade your operations. What does that mean? Did you have an existing Active Directory environment? If so, how did you migrate into the SBS environment? Are you saying that Exchange worked fine with the exception of working under the incorrect SMTP (email) domain name? Or did you mean you didnt like the name of the internal Active Directory domain name? If you just want exchange to send and receive email under another SMTP domain, this is an easy task that does not require adjustment to the POP or SMTP connector. If you simply re-run the connect to the internet wizard you can specify additional domain names here. Please let me know if this accurately describes your issue. If I can help you through that process as well as fix the POP and SMTP connectors which are likely not working anymore.

Well, we 'upgraded' operations alright, from peer-to-peer to SBS 2003. And yes, I have been to the book store and online here in TechNet for some general tutorial type stuff. No previous Active Directory environment.I did pick up a book on SBS 2003, so far it looks good, but it will take some going through to see how some things do and don't relate.I didn't origianlly use the wizards for initial setup of Users and Computers and when I went through the Exchange Wizard it did appropriately update the user profiles I had made. A name change for the company also accompanied the network upgrade and that is where the problems began. I know I can rerun the Wizard but wasn't sure if that would change the base name for outgoing SMTP. I also know that I can generate specific changes to certain users, (I believe through their mailbox properties). I'm just not sure which is easiest, most complete and fool-proof. (I need that one the most, :).Thanks for the answer thus far!
