This morning, Windows Live Mail opened with over 2000 incoming messages, dating back to 2011. Several 'Other Folders' had disappeared. Shaw technical support took a look but could not come up with any firm answer. It looks as if all of the content of the 'Other Folders' plus a huge backlog from the server?? were dumped back onto my Inbox. This is a Dell laptop running on Windows 8.1. I have a second laptop running on Windows 7 that booted up as left last night. Since there are automatic updates by both McAfee and Windows, and this only occurred on the Dell with Windows 8.1 it raises a question whether this is a problem with Windows 8.1 updates. I had to spend over three hours re-saving selected emails and deleting the rest.
