A client of ours uses Outlook 2007 on a Terminal Server. When he opens Outlook, the "Connect to outlook.office365.com" window that appears defaults to an e-mail address.
This produces an error to where the client cannot get into Outlook. The only way around this error is to hit the drop-down list in that window and for the client to choose his own e-mail address.
So, what steps need to be taken to remove the default e-mail address that prevents getting into Outlook?
