The msExchMailboxGuid that is attached to a user object is the same for the main store and the RSG. If you edit msExchMailboxGuid, then the user will become detached from their mailbox - IIRC Exchange will just create a new empty mailbox next time it should be accessed using the whatever msExchMailboxGuid is set to as a reference.

Restoring a store to the RSG will not overwrite the main store. Users will continue to access the main store. What I would suggest is that you take all the msExchMailboxGuid exmerge doesn’t recognise from the RSG and create dummy accounts so you can dump the mail out then re-import it to the actual accounts.

The RSG is referenced totally seperately from the main store - a user will still connect to their mbox on the main store.

Does this mean that when I edit the GUID using the AD editing tool, I’m only editing it *for the RSG* and not for the main store? I have a situation where a server had to be rebuilt from scratch and users have been using the new system for several weeks. I have a backup from before the crash (from the OLD server) and want to extract mail from it, but I don’t want to break the new server and the accounts on it (and I really don’t want to lose all their new email that has come in during the last few weeks). Can I do this? (Sorry to ask general help questions here, just hoping someone will stumble upon it as this is the best information I’ve found online about actually using exmerge!)

Very nice work, helped me recover several boxes that were deleted months ago. I ran this several times without issue but all of a sudden I can’t do this anymore. I can get the user’s mailbox to show up in exmerge using the guid trick but when I try to export the data to a PST I get the following error:

“Error opening message store (MSEMS). Verify that the Microsoft Exchange Information Store service is running and that you have the correct permissions to log on. (0×8004011d)”

Any idea’s?

I checked all my permissions and that doesn’t seem to be an issue.
