Hello All. I have noticed that when I change my password in windows that exchange 2007 will still let me log-on with both the old password and the new password. However I cannot use the old password to login to windows, only the new password. Is there something in exchange that remembers the last password and still considers it valid? I am running a 2003 environment in 2003 mode and have two DC's that I forced replication on to make sure that wasnt the issue.
