Good day. My Outlook 2007 connected to our Exchange server has started requesting my network password every few minutes, and I must enter it 3 times in a row before the window goes away. Selecting the Remember My Password check-box has no effect. There are no changes to my OS or Office/Outlook 2007 that should have caused this to happen. This problem only just appeared as I've been using Outlook 2007 with our exchange since installing Win7RC 5 weeks ago. I have deleted my password entry to our network proxy from the vault, then reentered the password when attempting to access the internet so it would be recreated. I've deleted my exchange account from Outlook 2007, reentered it via Mail in Control Panel, started up Outlook 2007 and all was good for about 2 hours, then the Username and Password box started appearing every few minutes again. Any suggestions how to correct this most annoying problem? This proxy authentication box has appeared 12 times while typing out this message, and it only appears when Outlook 2007 is connected to the exchange server. Thank you.
