In theory a great tool...
We have been using it to automatically update our virtual unified inboxes and sent folders over different accounts and growing user subfolders. But we keep having problems with our virtual folders now either showing no mails at all (this happens mostly in virtual folders of "sent items") or duplicate mails showing (apparently while updating subfolders the plugin checks parent folder AND all subfolders)...
Deactivating the tool solves those problems immediately.

Unfortunately we now have to update new folders manually again...
