Hi I have just migrated from sbs Exchnage 2003 to sbs Exchange 2007. Out of a sudden, the outlook 2007 client keep prompting for user name and password. Even i have entered the correct username and password, it will prompt again immediately.
i have went to the below article and make some registry change and still not working.
i am not too sure what i did for a while it was working and it happen again after i rebooted the server.
Please kindly help.
