Hi Everyone, I'm sure this has been asked in the past so I do apologize for duplicating it but it’s rather difficult to put this into a search for me so I thought it best to start this general discussing. Anyway, I'm looking for a KB article or whitepaper that outlines what the difference between Exchange 2003 and Exchange 2010 and more specifically how they handle password replication. What I mean by this is when a users password changes on the AD side it does not prompt the user to enter a new password on a mobile device in an Exchange 2003 environment unless the Information Store service is restarted "at least not in ours" it simply locks the user out after the companies password policy threashold has been reached for number of failed attempts. I'm told Exchange 2010 fixes this problem, but really just would like to see some literature to support that fact if such material is out there. Any guidance is appreciated Thank you in advance Michael Thanks Michael Cronin
