My company uses Outlook 2007 connected to an Exchange 2003 server with auto-discover. The user profile will auto-connect to the exchange and find the mailbox, configure all settings and launch the Mailbox. However, after the initial setup, it will prompt for login credentials. Whether you put them in, incorrectly or not, or simply hit Escape to close the window the mailbox will send/receive email, but it will say "Need Password" down in the status bar. After you close the login window, you can right click on "Need Password" in the status bar, choose "Enter exchange password and connect" and without a login box popping up, it will say "Connected to Microsoft Exchange" and all is well for a few hours.
- I have found that if "Cached Exchange Mode" is turned off, the problem disappears leading me to believe it's based around the Global Offline Address List. This however will not work for all of our users so I need to find a solution.
- Exchange 2003 was moved from one server to another that was recently freed up and had better hardware
- After the move, the RUS was found to be pointing to our old exchange server so mailboxes were not being created. That has been resolved.
- IIS is set to use Windows authentication on everything but "Default Web Site"
Thank you all in advance for whatever help you can provide.
