Outlook 2010 continuously prompts for username and password

I am having a problem where Outlook 2010 continuously prompts users for username and password. I have verified that the network connection to the domain and exchange is stable. I have 30 users on the network but only about 10 have reported as having a problem. The problem occurs intermittently during the day.

Check your DNS

Also if you create a new user on an affected PC does it also have the problem/prompts ?

Have you tried repair/reinstall of office
E-Z-D

have these users recently changed their password?

if yes: have them enter their old password first (dont save credentials)
when outlook asks again, type the new password (and save credentials)

if no: open a cmd /admin and type "control /name Microsoft.CredentialManager" without quotes

the credential vault will open.
look for anything that looks like MSoutlook:emailaddress ... and remove them from the vault.

restart outlook and type in the credentials one more time, save credentials.

When ever you get the OL prompting, close all browsers run netstat -a and check which servers is your OL trying to connect.

Some times, it may be connecting to wrong IP Address or port - you never know.

Resetting password can only be checked/worked upon if webmail too doesnt allow you to login and browse emails.
