Since move Exchange 5.5 server to new one get some users with the credential window (asking for username, password and domain name)coming randomly even if they have been authanticated successfully when started outlook minutes or hours ago. No error message is display, just the window. If cancel 6 to 8 times logon back. This window comes only if they use Outlook, if open but not use never get it
Use NT Password Authantication
Redo outlook profile, reinstall Outlook98 for few users OK but not all…Again it is a RANDOM scenario and get it with NT4 and Win95
What can I do?
