Hi Experts, Just observed one problem when trying to change password in Exchange Server 2007 on Windows server 2008-R2. An old password still works after you change it in Outlook Web Access. After 20-30 min its fixed and only new passwords are working. I tried to follow some articles still not any success. Checked replication by command and created deleted objects, they are immediately in effect. Followed : http://support.microsoft.com/kb/267568 but no go. Any suggestion please. Regards Suman B. Singh

Hello Suman, This behavior is by design. We can change the password in AD, and it will work immediately, but there will be a 15 minutes delay before OWA changing this password. Which means that during this 15 minutes period, we can log on OWA by using both old password and new password. Try that link to change the default interval.Thanks Mouzzam Hussain Visit to my Blog mouzzamh.wordpress.com
