I installed my new PC and in outlook I have this problem. I made my account as on the old pc but I have two the same datafiles now -firstname.lastname@example.org. The one under backup is in use now. Now I wanted to move all the subfolders from the acount (above back up ) but I get always that error. Cannot move the items. This folder cannot contain subfolders ..... see attached jpeg ! anybody knowss what's wrong ?
