Im on a 64bit version of windows 8.1 with office 365.
I had completed email and pressed send but it hung in outbox unable to connect. rebooted the hub and then shut down the pc and rebooted that got the normal message exit without sending send later. when I went to close down the PC it said updates installing, waited for those to complete and then restarted. went to open outlook from a shortcut on the desktop and got a message that the shortcut was no longer connected and asked if i wanted to delete. i deleted as knew i had the main app on the next screen down (not sure what its called old start menu) but when I went there that has gone too. exel app still working but no outlook and more importantly an email that I will not be able to craft as well again.
