Running Surface pro with win 8.1.  Email app provides email access. System has created a second junk folder and transferred all junk mail to it. Moved all junk mail out to first junk folder and attempted to delete second folder. Got alert that says can't do the action.  When I designate a msg as junk it moves to the second folder.  Megs moved to first junk folder did not appear there although they disappeared from second folder. First folder continuous sync spinning symbol. Have rebooted and restarted system and problem continues. 

How do I kill the continuos sync on the one folder and eliminate one or the other of the junk folders?
