Hi Rajnish, This is what I know. I'm not quite sure about a a E2K server being backend of a E5.5 OWA server. But, you could accomplish the same with E5.5 only. Your mail didn't specify some details, but I assume when you say Site, you didn't mean E5.5 sites but two different remote locations. If so, I assume you have only one E5.5 site. If this is true, you just have to add a new E5.5 server to that site. This server automatically will receive a copy of the existing directory of that site. Remember that E5.5 don´t work with Active Directory and it has its own directory. Once you added the new E5.5 to that site, your existing OWA server will be front end server of the newly-added E5.5 server. That's why OWA 5.5 queries E5.5 directory to find out which server on the site contains the requested mailbox contents. Since your newly-added server will be part of that directory, this will work.

I have 2 site named Site A and Site B On Site A I have the following servers:- Srv1 --> Having ISA, Exchange 5.5 (Mailbox & OWA, mainly used as SMTP), IIS, acting as domain controller Srv2 --> Having Domain controller (Master) Srv4 --> Having windows 2000 and Exchange 5.5 IMC (All in coming mails & Archiving) Site B:- Srv5 --> Windows 2000 Replica Domain controller for site A, Exchange 5.5 server- member of same site as of Site A. Solution required:- We need to install a new Server on Site A which will be exchange 2000 server. This server has to be a member server to existing domain and will maintain user's mailbox but has to act as a backend server for Srv1 in Site A If I use Microsoft Swing method to move the mailboxes. What will be the effect on existing exchange servers? Will Srv1 act as a front end server? If not, how can I configure the existing exchange 5.5 to act as a front end server for the newly installed exchange 2000 server?
