Microsoft 365 users worldwide faced a significant disruption today as a system outage impacted key services, including Office web applications and the Microsoft 365 Admin Center. Users attempting to access web-based tools such as Outlook and OneDrive were greeted with error messages stating, "We're experiencing a service outage. All of your open files have been saved. It may be some time before the outage is resolved."

What Happened?

Microsoft identified the root cause as a token generation issue within their authentication infrastructure. This malfunction disrupted access to several web-based services, leaving businesses scrambling for workarounds.

What’s Affected?

The outage primarily impacts:

• Office web apps such as Outlook, Word, and Excel
• The Microsoft 365 Admin Center
• OneDrive for web

If your team relies heavily on these tools, this outage can be frustrating and disruptive. However, desktop versions of Microsoft 365 applications remain functional, provided your licensing supports them.

A Recurring Issue?

This isn't the first disruption of its kind. Just two weeks ago, another outage caused widespread downtime across Microsoft 365 services, including Microsoft Teams and Outlook. These recurring incidents highlight the importance of having contingency plans in place for such scenarios.

What Can You Do?

1. Switch to Desktop Applications: For users with licensed desktop apps, continue your work using these local versions while Microsoft resolves the issue.
2. Monitor Updates: Keep an eye on Microsoft’s service status page or rely on BMIT for timely updates.
3. Contact Support: If your workflow is severely impacted, Boston Managed IT is here to assist with guidance and alternatives.
