We have a SharePoint webserver at our company. We sync contact list updates from the SharePoint server to our users who have Outlook.
Basically, when our users open Outlook, they are met with a login prompt as seen in the attachment to this post.
This is the credential prompt for our SharePoint server so it will sync their contact lists up.
Normally, the window comes pre-populated with a username and password, as seen in the attachment as well. This is because we use the "remember my credentials" feature that comes with that prompt.
However, now about 20 of our users are having problems when they open Outlook. The username and password boxes are completely blank.
To fix this, we go into Windows Credential Manager on their individual computer and add their credentials to the generic credentials section. This fixed the issue temporarily, for maybe a day or two. When they would restart or shut down the computer and power it back on, the credentials would be gone from the Windows Credential Manager. It would just appear to be blank, as if nothing was ever entered there.
This only started happening a couple of weeks ago. It was never a problem until then, so I'm wondering if some Windows update did something to break the credential manager. I have looked up various solutions for this and cannot seem to find one that works. These users are calling me multiple times a day, complaining that their Outlook lost the credentials, even after I've stored them in there several times. I even turned the credential manager service to 'automatic' instead of 'manual', but this did not make a difference.
Is anyone else having this problem? What can I do to fix it?
PS: Sorry if this is in the wrong forum, it just seems to be happening to our Windows 7 users, so I figured it was a Windows 7 issue.
Thanks in advance!
