    Hello,

    Has there been any solution yet on this problem. I too am getting this problem recently. I use Microsoft 365, and have tried the responses here, but to no avail.

    This is the kind of error message:

    A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

     ******@name.com (example of email ID)

    Unfortunately no solution yet. I experience the problem continuously but only if I send messages to certain email accounts.

    Good morning Dipta,

    I am not sure for the problem being resolved as I moved to Microsoft 365 Platform for my email but will follow up again for the ticket that I had created with Microsoft and provide an update when I hear back.

    Hopefully Microsoft is still looking at this critical issue and will come up with a solution to it soon.

    Thanks
