Question
How do I change my email address in exchange. I need to change from my oldemail@gmail.com to a newemail@gmail.com. I simply am not able to find this setting in my outlook exchange options

Thanks

AnswerThere are several ways to skin this cat.

1. Change the alias of your account (not recommended unless you are changing the entire name of the account)
2. Add new SMTP address and make it your primary (recommended)
3. Create new account and merge all the Outlook info to the new account (really not recommended)



1. this option has some consequences to note, so read about them here:
http://www.amset.info/exchange/usernamechange.asp

Open Active Directory Users and Computers mmc
Locate your AD account and right click-->Properties
Click on the Mailbox Store tab
Change the alias
Wait for Recipient Update Services to refresh your email address, check the Email Addresses tab in 15 minutes


2.
Right click on user again, and choose Properties.
Click on the "Email Addresses" tab.
Add the new email address in the same format as your existing email addresses. Leave the old address in place.
Change the default (set as primary) address to the new one.
By doing this, any email sent in on the old address will still be delivered, but all new email will go out with the new address.
uncheck auto update email addresses based on recipient policy, or your primary will be switched back to the alias generated address

3.
LOTS of work, but you can do it, if you really want to.
