Problem with Exchange 2007 – Authentication Pop-Up box in Outlook

Asked By 0 points N/A Posted on -

Hi all,

Can anyone please help with our annoying Outlook 2007 problem?

When staffs open Outlook, they are being asked to authenticate to our mail server –

If they pop in with their user/password, they can then load outlook and carry on as normal. OR

If they first login to OWA, they can then load Outlook.

Does anyone please know what is going on?

Also, here are the internet requests I captured with putty when they enter their credentials. Should Outlook in school be accessing webmail on https??

Thanks in advance!

If your Microsoft Office Outlook 2007 is configured properly then I think this problem wouldn’t happen. If this is the first time that this happens when accessing Microsoft Office Outlook, try closing the application, restart your computer then try it again.

See if you don’t receive any dialog box popping up after rebooting the system. If it’s the same, try checking the settings of the application. I suspect that the software is really not configured properly.

If it still doesn’t work, you may also try doing a clean installation of the program to fix and clear your system from any corrupted files that may be present in your computer. Uninstall Microsoft Office Outlook 2007 then restart your computer.

If this program is part of the Microsoft Office package installed on your machine, just remove only this feature and leave the rest of the programs as it was. Check your computer for any possible errors.

Use a disk utility application to check the system. Install Microsoft Office Outlook 2007 then check if this fixes the problem. Be sure to supply the application with the correct username, password, smtp address, and or port number.
