This is an interesting situation we just encountered that I thought others would be interested in.
In our test environment, we recently upgraded one of the E2K servers to SP3. Afterwards, for various reasons, we needed to go back to an SP2 version of the database, so we tried to restore the older databases, but were getting JET errors. After talking with Microsoft, we found out that once an Exchange Server is upgraded to a newer service pack, you cannot recover an older-version database using the later-version Exchange server. This applies to 3rd party backup software, as well as native Win2K backups. This means that if, for compliance or business reasons, you need to keep older versions of your databases archived, you need to know which version of the software that database last ran under. In addition you would need to make sure that when you restore, you must do so on a server that is patched only to that level of Service Pack. Apparently this applies to the Private IS only, and not Public IS. Once you mount the older-version database on its corresponding server, you can then dismount it and move it to a newer version server so that you can use it (if necessary). If you have any other information about this, I'd be interested in reading your responses.
