Hello,
We have an customer where they have hybrid configuration between office 365 and Linux mail server.
- MX pointed to Linux mail Server.
- They have several users migrated to office 365 with forwarding from Linux and connectors from office 365.
They wanted to setup POP3 in Outlook application using below configuration where they wanted to use office 365 as incoming mail server and Linux mail server as outgoing mail server.
Setting Type: POP3
Incoming Server: outlook.office365.com
Port: 995
Type: SSL
Outgoing Server: mail.contoso.com
Port: 25
Type: Auto
But not working. Please request an suggest for the issue.
