This article will help you change the username of a profile where the exchange settings haven’t changed but the username/default email account has been changed on the exchange server or in the hosted exchange portal.

To do this please follow the below steps. In this example we will be changing the address livetest@domain.com.au to testing@domain.com.au:

1. Close Outlook and re-open Outlook.

2. Once Outlook opens up you should be prompted with a Windows Security pop-up. Select Use another account.

3. Enter the new email address and your password. Ensure that you tick the box Remember my credentials. Click OK.
