How to delete a glitched draft message in Outlook?

Question

Outlook

Good afternoon. Prompt, pzhlst, on such a problem. There are Outlook 2016 and IMAP Mail.ru. Literally last week everything was ok, but now some kind of trouble. Let me remind you that in autgluk it is implemented that if you write a response, but do not send it, it saves a draft, and this draft is visible directly on the message in the Inbox. When replying to any message, the following happens to me:
1. The message is normally sent to the person who wrote it (this is where it should have ended, but ...)
2. Outlook saves the draft of the sent (!) message (i.e. I see the draft in inbox)
3. I'm trying to delete a draft of this message
4. The trash is starting to fill up with copies of this draft, but the draft is still not deleted!
And so it is with every letter. Some people actually delete drafts. But why do they even appear? What could it be?
