Found this:

But it doesn't even begin to touch on the intricacies of where things need to be placed in order to run the restore operations.   It is also misleading as to where you execute these operations from.   Says to select the domain, first and then use the "..." to get to those options for what to restore.   But the what to restore is actually at the Full List of domains level only, doesn't matter what domain is selected as you have to specify the emailbox you are dealing with.   For such a critical (and common) operation, this documentation needs a severe overhaul.

Hey Rod! The instructions you linked are detailing the restoration process for the backup of an entire user account, an entire missing folder, or an entire missing domain - so that is why these instructions aren't lining up with what you're expecting. If you're just restoring specific mail data that went missing the easiest way to do that is: 

1. Create a folder called Restore and drop the missing GRP files into it. 

2. Move the Restore folder into the user's mail data pathing. 

3. In SmarterMail from the Manage page; click ...>Attach Folder then complete those settings including the username and folder path location.

That will cause SmarterMail to index that folder and attach it in webmail so the user can move the missing email back to where it belongs. I hope that helps!

Thanks for the update Kyle.

This one is a bit more involved... the client has probably 4 dozen folders that need to be restored as well.

So do I just create them all under that Restore location with however the .grp files are organized and then execute the Attach Folder on that same Restore folder with the Recursive option active?  Will that handle all those folders then ?

I can't believe in all the years we've run the SM server we've never had to do this before... lol

Hey Rod, sorry for the delay on this one. That should do the trick yes! If you have CFGs present in the backup subfolders you should be okay to leave those in there as well, and we should update them as needed. If you want some help testing that restore beforehand please don't hesitate to submit a ticket.
