Try this, edit /etc/ssl/openssl.cnf

Edit or add this to:

Code: Select all

[system_default_sect]
MinProtocol = TLSv1.2
CipherString = DEFAULT@SECLEVEL=1
Modern systems have set the Seclevel to 2, very old programs can't deal with that.

It may solve it. As Seclevel 2 has a higher encrytion than the level 0 and level 1, still used by old programs.

You could also try edit the TLS version to 1.1 or 1.0.
Greetings Bas.

Outlook before 2019 supports only POP3.
Do not try IMAP.

Don't think so, one of my clients uses it with IMAP.

Hello

1) Have a look into the logs when connecting.

2) As the customer uses outdated software, lower the "Minimal TLS protocol version" here settings: Configuration -> TLS Version & Ciphers and use the appropriate ciphers https://ssl-config.mozilla.org/
Be aware that you are lowering the security of the entire server and all customers and should rather encourage the customer to update, not only for the sake of your other customers / of your server, but also for his own sake.
Mit freundlichen Grüßen / Best regards
