I am having trouble with changing email addresses. Its exchange 2003 running on Windows2003 server. Question one: With exchange 2003 I have a user who logs onto the domain with the user name hind. His email is currently hind@shallweek.co.za I want to change his email address to SmithH@shallweek.co.za without changing his domain logon user name. In the AD interface, I double click on hind to access hind properties on the tab E-mail addresses just below the tab it says Each e-mail address type has one default reply address. To change the default, slect an entry in the list, and then click Set As Primary. there are options buttons below new edit remove. I tried adding SmithH@shallweek.co.za. Here and setting it to primary. But mail to that address fails. How do I change his email address to SmithH@shallweek.co.za???? Question two: In the same screen on another account the primary reply address is set to the following domain. Joe@haalmotors.co.za. Also listed in the same screen is Joe@motorworld.co.za. If I select joe@motorworld.co.za as the primary, and send mail to that address, it fails, how do I correct this so that people can send to joe@motorworld.co.za???? Thanks in advance for your help.

Hi For question one: It should work if you added a SMTP Email address. Did you add the SMTP address or other address type? For question two: If changing another email domain like this, It still works for sending emails in internal. But for external mail flow, you should make email domain name resolved, otherwise, internal message sending to this address will not locate the mail server and NDR would report. -Jason
