I have Exchange 2000 (for POP in branch) and a Exchange 2007 (for Outlook in HQ) in Data Center, and using a 4M Site to Site VPN connect to HQ with same AD HQ Outlook User always lost the connectionto Exchange, especially when user download a big attachment. I am considering that Move the Exchange 2007 to HQ, user can direct connect the server by LAN, but incomming email will arrive the data center and pass to HQ by VPN is it agood senario?

Hi, Of course, it is a good scenario. You can implement it. Thanks Allen
