Issue Plesk with office 365

[ALI Zawawi]

Hello ,
this is my first question in the forum , we are using plesk for arround 2 years and we was able to solve all problems as far .
now we are forcing the following issue:
customer have his own plesk hosted on our dedicated server as virtual machine installed postfix mail server and customer have 2 main domain and multi subdomains.
only main domain have email addresse , we have configured 2 email addresses from this 2 domains on office 365 ,
so [email protected] and [email protected] are now in office 365 and the rest of emails are local in plesk .
i build 2 connectors in office 365 to mail flow between office 365 and on premise (plesk) as far we can send email to office 365 [email protected] and [email protected] and we can also send from this domain to external .we can also send from plesk emails to external , we can recieve emails from externla to internal over the office 365 connector, and we can send from office 365 to intern over the connector ,
the olny issue is we cannot send from plesk intern to office 365 like from [email protected](plesk) to [email protected](office 365) .
i tryed the following instruction in the link How to configure postfix relay to Office365 on Ubuntu 14.04 without success.
have any one a idea how to complette this cofiguration on the plesk side.
thank you
sorry for my bad englich

DNS is causing mail to stay local, the internal messages are staying in the local boxes.

Split Domain Routing is what you are looking for.

Example; You need to create o365.domain1.de as an alias domain in Office365. The email accounts in Plesk then need to be setup as Forwarders to the same user at the alias domain.

This link explains it well; Split Domain Routing: Getting Email for Your Domain at Two Providers - LuxSci

Hello Ali,

I want to achieve the same as you but, I already have problems with the office 365 connectors. I have a domain and some emails are on office365. Do you have a tutorial you followed for setting up the differnt things?

Currently I have

• [email protected]
• [email protected]

hosted with Office 365 and

• [email protected]
• [email protected]

on Plesk.
From my web application I am using [email protected] to send e-mails to both: [email protected] and external e-mails (e.g. [email protected]).

But from Plesk I cannot send e-mails to my office 365 users.
Also I cannot create the office365 connectors as it always tells me some errors I can't find anything and microsoft support was not helping at all (
401 4.5.4 Invalid arguments - possible version mismatch [BE0DEU01FT004.eop-deu01.prod.protection.outlook.com])

Best regards
Michael

Hello Ali,

Can you describe how set up the connectors? I have the same issue as Michael. Thanks.

Hi,
the other possibility is, point the MX to plesk and setup Forwarder to the @Tandent.onmicrosoft.com Address. Is not the nice one, but it depends on your need.
In generell I highly recomend to not try to make Hybrid with Office 365 an Plesk. If you would like to read mor about Plesk and Office 365, take a look to my Blog: https://www.infrastructureheroes.org/microsoft-infrastructure/microsoft-exchange/preparing-the-mail-flow-for-the-office-365-migration/

Kind regards
