Yes, I face exactly the same. Was always able to do it. Don't know who to connect about this, the Microsoft case is closed because dev tenants are out their support.

      Jack_Chen1780this is a piss poor response from Microsoft. According to their own documentaiton (Option 3) you need to create an inbound connector.

        vand3rlinden We had the same issue. we used 2 dev tenants to test very complex scenarios, we were in the middle of doing a very complex migration. Microsoft by turning off this feature with no notice not only pushed our project back with huge costs but also literally leaves no options for consultants like us to test different scenarios. hard to believe that a tech giant like Microsoft had to resort to this option to resolve 'SPAM' issues, and had no other smart technical solution.
