Using Exchange 2007, the Outlook on my PC keeps asking for my password..
The PC is wired to the LAN, it was upgraded from Office 2003.
The problem was found to be cached passwords on a Windows 7 desktop.
>Open Control Panel
> User Accounts
> Manage Your Credentials
> Look under Generic Credentials.
Edit: MS.Outlook:username@domainname:PUT and change the password.
There was another entry for the domain that I completely deleted.
Deleting the entry mentioned above may also resolve the problem? However that was not tested.
