'"Failed to read TLS record (2)" connecting to office365 IMAP using Chilcat ActiveX

We used to have internal Exchange and connection worked. Now the Exchange server is migrated to Office365 cloud, and I cannot connect.

EXEC sp_OASetProperty @imap, 'SslProtocol', 'TLS 1.2 or higher'
EXEC sp_OASetProperty @imap, 'Ssl', '1'
EXEC sp_OASetProperty @imap, 'Port', '993'
EXEC sp_OAMethod @imap, 'Connect', @success OUT, 'outlook.office365.com'

It seems that the first handshake is OK, but the second fails. Any ideas?
