microsoft outlook asks password when ever user change passwords

view full story

http://serverfault.com – I have a 10000 users with different OUs, groups. We have a windows 2008 AD server and a exchange 2010 mail server. clients are using windows 7 64bit OS and outlook 32 bit. When ever users change their password, outlook and lyncs keep on prompting passwords from the user even the users enter the correct user name and password. This causes the account lockout issue. So we are facing large number of tickets on this issue only. What we do is restart the machine, remove the saved password from the vault. can any one have the solution for this.
