I had problems updating from Windows 8 to Windows 8.1. This was resolved today by MS on a remote session but as my Microsoft account was corrupt they had to close it and reopen one using same email address. Everything has been reinstated including OFFICE 365, however if I try to delete an email I get a message "The operation cannot be performed because the object has been deleted".
The other problem is sending emails. I thought they were getting stuck in the Outbox until I received a reply to one. So it appears they are being sent but staying in the Outbox rather than dropping into the sent folder. Not sure which problem is the most serious but really cannot live with either. Support is closed, so wonder if anyone has any ideas what I could try.
