Please note that our forum is a public platform. Kindly ensure that you hide any personal or organizational information to protect personal data.
Just a quick note that this forum is a peer-to-peer community where members and advisors can share suggestions, troubleshooting steps, and experiences based on similar situations. However, community members do not have access to Microsoft's internal support systems and therefore cannot view the status of support tickets, communicate with the assigned support engineer, or provide updates on active cases.
Since this is a support ticket being handled directly by Microsoft Support, the best course of action would be to reply to the most recent email from the assigned Support Engineer or contact Microsoft Support again and reference your ticket number. They will be able to provide the latest information regarding the investigation and any next steps.
If you are experiencing issues sending messages to the domain, you may want to check whether you are receiving any bounce-back or non-delivery messages, as these can provide useful clues about the cause of the issue. Sharing any error codes or messages with Microsoft Support may also help them investigate more efficiently.
In the meantime, while waiting for an update from Microsoft Support, please check whether you receive any bounce-back or non-delivery report (NDR) messages. If so, sharing the complete error message with Microsoft Support may help them investigate the issue more efficiently.
If the issue affects a business domain such as demariamitsubishi.com.au, the domain administrators or Microsoft Support would typically be responsible for reviewing domain-level settings and mail flow configuration as part of their investigation.
You may also wish to review any recent support-related emails from Microsoft, as updates or requests for additional information are often sent to the email address associated with the support case.
I know that waiting for an update can be frustrating, especially when email communication is affected. Unfortunately, the community is unable to access or expedite support cases, so contacting the assigned support team directly remains the best way to obtain the latest status.
I hope this information is helpful. If you have any further questions, please feel free to post back in the comments section.
