I am migrating from Exchange 2003 to Exchange 2007 so I am in coexistence mode. Somehow, someone managed to move or delete a public folder containing important contact data. Unfortunately, I did not realize that the setting had not been enabled to allow for the easy recovery of deleted items from the public folder store. So now, I am faced with how to recover this particular public folder. I have several NTBackup files from the Exchange 2003 and Exchange 2007 servers that I could use. I do not understand why Exchange server does not allow public folder recovery using a RSG. Anyway, now I am wondering if I can dismount the current public folder store temporarily, restore the public folder store from ntbackup, copy out the data I need from the public folder store created from backup, then discmount it and remount the current public folder store that was temporarily taken offline. It seems like it should be possilbe, but I thought I would check before I mess something up. Any thoughts?
