I'm using Outlook 2010 on Windows 10. Two things have happened in the last 48 hours to my Outlook Inbox:

-all Read messages left in my Inbox over 14 days have disappeared. (This hasn't happened to anything moved to Trash or to Folders or to anything marked as Sent).

- Messages in my Inbox that I have marked as Delete appear with a strikethrough until, periodically during the day, they are moved to Trash, but not by me.

I haven't Auto-Archived anything, not have I created any Rule.

Does anybody have a clue as to what may have happened and, especially, if there's a way I can recover the Read messages?



Thanks.
