Hello Experts,

We are in the process of migrating our mailboxes (exchange 2003) from our remote site and centralizing them in our main data center which will be accessible through a WAN connection. At the same time we will be joining our local clients to the domain of our main data center. When this happens even if the maiboxes are migrated to the main data center, a new .OST file will be created when every user is disjoint from his current domain and joint to the domain of the main data center (since cached exchange mode is enabled). Now the problem is that we do not have mailbox size limits set for our local users, so recreation of an OST file for a user who has a 4 gb mailbox across an 8 mbps wan link will take ages. Is there a way.OST files can be migrated across to minimize the effort?

Actually, I /think/ that unless you're migrating AD accounts you don't need to do a migration. The OST file isn't tied to the local user account, it's tied to the mailbox which is attached to the AD account. The local users have to provide AD credentials so you don't have a problem.

But if you've tested this already and you do have a problem, let me know, because it's obviously working differently than I remember.

As a matter of fact we are migrating AD accounts as well into our main domain at our main data center and thus the problem. Please advise. Thanks very much for your reply, appreciate your help.
