( ps i did a screen dump but could figure out how to insert it, you would think after all this time I would have learnt by now :-) )
n00dy: there is only one profile lieted, i even deleted complete profile and email account etc but when i created a new one it is still there. I tried resetting all form data in IE ( as i thought it might have been a saved form ) but still no success
xpd: Any 3rd party Outlook plugins etc that were being used ?
Hiamie: If what you describe is a normal drop down box, you just highlight the name with the mouse (no need to click- it should highlight with a blue background when you hover the mouse over it), and press 'delete'.
It has an option to delete remembered entries in various parts of windows.
