Hi,

Our Network is a single AD domain distributed across two sites (Site 1, Site 2). Each site got One exchange server 2003 with latest patches and SP's on Windows2003R2 Servers. If a new user account is created on Site 1 which got Exch01, every thing works fine. If create user account on Site2 which got Exhc02 I can see user account is created without any errors & all the account properties including emails addresses and every thing else propogated across to Site 1 but the mailbox nevers creates on the Exch02 database not even after a month. That new AD account can logon to domain computers and all the Security Permissions work as mentioned and also appears under GAL, but the Mailbox never creates. I did try sending email and logging on using OWA etc.
And also while creating the new user account on Site 01, Exch01 if select the user mailbox to store on Site 2, Exch 02 database, the above mentioned problem appears. No errors every thing propogates but the Mailbox doesn't create.
The only work around which we are using now is creating a mailbox on Site 1 and using Exchange Tools to move to Site 2.

I did check the RUS by going through Diagnositics Logging, I already gone through RUS rebuild and every thing. No error appears and nothing strange. AD replication and DNS updates propogate no errors. Analysed the traffic between the sites related to LDAP nothing blocked and no errors either. Even the Application event log on both the Exchange and AD sites are pretty clear, even after enabling the Diagnostics Logging for most of the Exchange Related stuff.

Any help appreciated.


Thanks
