Question Trouble adding IMAP Account on Outlook New

[Lanklan_]

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

18.0.66

Good evening,

I'm having a lot of trouble adding a mailbox in the new version of Outlook (mandatory next month) under Windows 11.

Regardless of the use of the protocol (IMAP or POP3), I always get the same error: INVALID IDENTIFIERS.

No problem under MacOS and/or Outlook Classic (which will disappear under Windows 11)

How to solve the problem?

Thanks

Hi,

Use the same server addresses used by Outlook Classic. The new Outlook might try to use mail.domain.tld even though that server address is not covered by the mail service.
Furthermore, Outlook new will not set up an email account if the server address is not covered by the SSL certificate returned by the mail server.
