Hello All,

I am almost at the end of an upgrade from Exchange 2007 to 2013. I have a handful of Room Resources that I had migrated to 2013 during the upgrade. Data was there and readable. We had an issue with our VM environment that corrupted the database these mailboxes were in.

I've recovered the Exchange 2007 database from a backup and it is mounted. I've tried migrating the mailbox back to 2007 then logging on to the calendar but it still shows blank. I also tried just re-homing the mailbox back to 2007, and the calendar still is blank. Both of these worked in the sense that the mailboxes were looking at the 2007 DB, confirmed by logging on to OWA as the resource.

Anyone have any idea how I can get the calendar info back? Also, any idea how I can look into the 2007 DB to see if the calendar is actually there but possibly not being accessed by the mailboxes?

Thanks,

Travis

Hi Travis,

Please create a new resource mailbox in Exchange 2007 and compare the Attribute in ADUC between new mailbox and old problematic resource mailbox.

Please confirm if the permission is configured correctly in AD and Exchange. We can assign mailbox Full Access permission to a regular user and open this resource mailbox in OWA to confirm whether the items are existing in Inbox and Calendar folders.

If the items are still invisible, please consider to export this mailbox to PST file and import it to the new resource mailbox to have a try.

Regards,

What I found yesterday is that no matter how I moved the mailbox back into 2007 (migration, or rehome) a temporary, or alternate mailbox with the same name was created in 2007. This is why everything was blank. When I tried the Microsoft tool in shell to export the mailbox to PST, it errored due to there being two mailboxes with the same alias.

I was able to use a third party software to access the database and export the correct mailbox to PST. I'm sure I could have used shell to remove the temp mailbox, then export to pst, but the software let me see what was in the mailbox quick and easy.

Thanks for the help,

As I told you, when you move the mailbox back, it ereases whatever was there.  You must do the mailbox back before copying the content from a recovery storage group.

I tried that method as well, with the same results.
