Update

All Mesh services are continuing to function normally, however, we are still seeing mail flow irregularities to Australian customers on Microsoft 365. This is not an issue specific to customers using Mesh.

Microsoft are now reporting that they have identified the cause and have put in a fix - https://x.com/MSFT365Status/status/1925482680646357013

We will continue to monitor.
