Rename a folder that has subfolders
I have a mail folder that contains subfolders. I can rename any subfolder by right-click->Rename Folder. However, I cannot rename the parent folder that contains those subfolders (e.g. <College> contains subfolders <Year 1>, <Subject A>, etc. <College> cannot be renamed. "Rename Folder" menu item is disabled.) Now I can't move the order of the folder to the bottom (aka, put a Z in front of the name, so that more recent folders are shown higher in the forced alphabetical sorting of all my folders. I have 19 subfolders in that folder, so it is a hassle to move all subfolders out before renaming.
