I am getting a message saying;
“A dialog box is open. Close it and try again.”
This happens when I try and create a new mail message. However there is no dialog box open.
This can happen when there is no user information specified for your version of Office. To resolve, you must fill in the user information.
Tools-> Options…-> tab Mail Format-> button Editor Options…-> tab Popular-> section: Personalize your copy of Microsoft Office
Outlook 2003 and previous
You’ll have to do this via Word
Tools-> Options…-> tab User Information
