Microsoft 365 Engineer: better Exchange Online message trace guidance
Microsoft 365 Engineer
The M365 advisor now walks through message trace in a clearer sequence and cites the Microsoft Learn pages it relies on.
Improvements
- Reordered the message trace troubleshooting steps so the first check is the most common cause.
- Added guidance for extended message trace retention and how it differs by plan.
- Every M365 answer now includes the Microsoft Learn sources it draws on.
