Evolution auto moves mails from Inbox to Junk

Evolution 3.20.5 from official repo

It’s working with Exchange via https://exchange.domain.ru/EWS/Exchange.asmx.
When I start Evolution, I can send/receive emails, but after some time (10-20min) it moves all mail from Inbox to Junk folder (without marking it as spam). After that, when I move all mails from Junk to Inbox, in a 10-20min Evolution moves all mail from Inbox to Junk once again.
I’ve no any filters in Evolution.

Any help?
