Recently, I have developed many problems with Outlook 365. The most serious problem, discovered just today, is that when I delete a message in my Inbox, it disappears; it does not go into the Trash folder.. There are many other problems. Another example is the Rules mechanism has stopped working. Rules are not being followed and it does not allow me to add new rules. There are many pther problems.
I have updated Office 365 as one Microsoft message suggested. No change,
