Hello and welcome to Apple Support Communities, dzmitry144!
I understand you're seeing duplicate messages appearing both in inbox and trash. I'd be happy to provide information to help you address this.
You may want to check if the same behavior occurs in webmail for those accounts. If it doesn't, try rebuilding the mailboxes: Rebuild mailboxes in Mail on Mac
Let us know the results.
Have a great day!

Web iCloud seems to work fine.
Rebuild was helpful for Mail Desktop App.
Thanks.
Mail displays same messages in different boxes.
