Trouble with received S/MIME messages - cannot be decoded

when receiving an encrypted email or even when sending an enrcypted email and receiving response on this email, the mail cannot be read in eM Client. However, if opening outlook for the same account and email, I can read this mail.

The S/MIME certificates are known ind imported to eM Client.

I’m using WIN 10 
eM Client 7.2.36908.0
and IMAP account for my inbox
