Logon to a PC as the new user. Create the profile in Outlook. Verify name etc. When I come to fire up Outlook for real, I get "The logon credentials supplied were incorrect. Make sure your username and domain are correct" . I then confirm the box displayed with username, domain and password and I get rejected again. This happens on two different workstations. Having trawled about I can find no helpful advise. Any idea's ?
