Secondary authentication for Outlook 2010
Posted on 2012-03-15
We are getting a pop up window asking for a user name and password when opening Outlook 2010. We have Exchange 2010 and just changed our email addresses to a new domain name.
Both the new and old email addresses work but it is annoying having to click on cancel on the pop up and click on need password on the lower right of the Outlook window.
Any help will be appreciated.
