  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

You can try this:
1. Log in the server via GUI.
2. Navigate to Tools&Settings > TLS versions and ciphers management > Settings
3. Update cipher by clicking on sync now
4. Re-try to configure outlook or mobile client.

or this:

1. Access the server over SSH.
2. Open the following file in text editor: /etc/dovecot/conf.d/11-plesk-security-ssl.conf.
3. Change ssl_min_protocol=TLSv1.3 to ssl_min_protocol=TLSv1.2.
4. Save the changes and close the file.
