Posted by [Systems Engineering](https://blog.systemsengineering.com/blog/author/systems-engineering)

Systems Engineering is aware of a Microsoft 365 service degradation currently affecting email services, including our own ability to send and receive email. This is a Microsoft-side issue and is not isolated to any single client environment.

You can see more information, including live status updates at Microsoft's service status page [here](https://status.cloud.microsoft/).

All of our internal platforms — including our service desk, remote monitoring and management, and security operations — continue to operate as normal, and our teams are closely monitoring the situation as Microsoft works to mitigate the issue.

We are not recommending any changes to your environment at this time. We urge patience while Microsoft restores service; unnecessary changes made during a provider-side outage can complicate recovery.

As always, please reach out to us via phone for urgent issues, we anticipate email flow resuming shortly, and are awaiting guidance on Microsoft should there be a need to re-send any emails sent during this service disruption.

Thank you for your patience.
