After restoring some mail stores, mounting them in the recovery storage group errors out. So far a repair with eseutil (which the log says was successful) and a server reboot has been tried. A defrag is currently running on the mail store
I need to go through this again to post the exact error codes, so I will be updating this question. But I thought someone who does this a lot might have a "More times than not..." answer in the meantime.
