Recently the Exchange hybrid team released the new “stand alone” hybrid wizard called “Microsoft Office 365 Hybrid Configuration Wizard” or HCW.

Today I decided to try it out in my lab to prepare myself for a migration.
I was amazed how easy it went. It was almost “next, next, finish”.
Only one thing didn’t work for me – the mailflow from on-premise to Office 365.
I started to investigate. First I took a look at the que. I could see the message from the outside, to on-prem. This message was supposed to be delivered to the user in the cloud.
Here is another view of the message in the que.
I took a look at the error message. My first thought was that it was a network error. “Connection timed out”.
I decided to test network connectivity. It worked as it should.
I then took a look at the Receive Connector in my Office 365 tennant. I saw the message to the right “How to identify email sent from your email server” and was thinking if it could be somthing with my “Send Connector”.
I went back to the on-prem server and took a look at the Send Connector. I saw that the “Assigned to services” was only assigned to IIS.
I then assigned the certificate to the SMTP service.
Now I did a retry on the que and took a look again, and the mail was delivered to Office 365.
I don’t know it the Hybrid Configuration Wizard – HCW – was supposed to assign the certificate to this service or not, but remember to check.
