If other mailboxes on the old BE are working fine via OWA, then check the new BE config..
Yes I am using a FE/BE topology. This issue is occurring after I have moved one test user to the newly added backend exchange server. OWA only resides on the FE server. However I am able to login while accessing the backend server directly.
Thanks & Regards
are you having a FE/BE topology..? or you are accessing owa on each of the two server..?
We have added a new Exchange backend server in the current setup and tried moving a test user mailbox using ESM. The process was completed successfully. However when we are trying to check the same using OWA it is giving “HTTP/1.1 503 Service Unavailable”. Please help me on this.
Thanks & Regards
1. Make the new server Exchange 2007
· Read: http://www.msexchange.org/tutorials/Transitioning-Exchange-2000-2003-Exchange-Server-2007-Part1.html or similar articles that cover migrating to E2k7 and retiring your E2k7 servers
· Recommend going with a CCR cluster, which requires at least 3 E2k7 server (CCR node 1, CCR node 2, HUB & CAS server)
o If you call all-in-one then HUB, CAS, & MBX roles can be on one system
· If you don’t go CCR then at least setup LCR
· If you do goto E2k7, you will need to replace your FE with a E2k7 CAS server before you move mailboxes to E2k7
2. Recommend adding at least one addition DC.

Since there is only 1000 Mailboxes in the Organization, new Back end server should be a well versed solution.
I will recommend you to distribute the mailboxes, so everything should go ok.

No cons really; this is the correct step. The only con is probably to considering migrating to 07 which will give you a that significant IO reduction via incremental memory.

The Current Exchange Setup is as follows:
# Frontend – Backend Setup
# 1 Frontend Server (with RPC over HTTPs proxy) + 1 Backend Server (1000 mailboxes) + 1 Domain Controller
# Windows 2003 Enterprise Server (SP2) + Exchange 2003 Enterprise Server (SP2).
We are planning to add an additional backend server with higher disk and I/O capacity and move the mailboxes on the new server.
The steps are broadly outlined as below:
1. Additional Server joining the Existing windows domain
Can somebody please guide me through the pros/cons of this setup or pre-defined checklist that one needs to take care of in this kind of migration.
Thanks & Regards
