Exoprise CloudReady provides early detection of mission-critical mail outages. On March 15, Microsoft had a service outage worldwide that impacted its services such as Teams AV, Yammer, OneDrive, and Azure Active Directory. As a result, end-users reported not being able to login into either of these services and were getting timeout messages. Services were down!
But check this out.
Exoprise detected the issue earlier at 3 pm EST (40 mins before Microsoft reported it). In addition, we were able to immediately relay the news to our customer base.

Preliminary Root Cause Analysis of the Microsoft 365 Outage M0244568
Microsoft recently updated the root cause for this outage and its to do with
- Ongoing, enhanced security protection with Azure AD
- Rotation of security keys
This is an excellent goal to pursue but, obviously, getting there can be a challenge. Read on for more insight into the cause and more detail can be found here: https://status.azure.com/en-us/status/history/
Preliminary RCA – Authentication errors across multiple Microsoft services (Tracking ID LN01-P8Z)
Summary of Impact: Starting approximately 19:00 UTC on March 15, 2021 customers may have encountered errors performing authentication operations for any Microsoft and third-party applications that depend on Azure Active Directory (Azure AD) for authentication.
The Azure Portal, Microsoft Teams, Exchange, Azure Key Vault, SharePoint, and other applications have recovered. Other applications are in the process of recovering and impacted customers will continue to receive updates regarding these.
Preliminary Root Cause: The preliminary analysis of this incident shows that an error occurred in the rotation of keys used to support Azure AD’s use of OpenID, and other, Identity standard protocols or cryptographic signing operations. As part of standard security hygiene, an automated system, on a time-based schedule, removes keys that are no longer in use.
Over the last few weeks, a particular key was marked as “retain” for longer than normal to support a complex cross-cloud migration. This exposed a bug where the automation incorrectly ignored that “retain” state, leading it to remove that particular key.
Metadata about the signing keys is published by Azure AD to a global location in line with Internet Identity standard protocols. Once the public metadata was changed at 19:00 UTC, applications using these protocols with Azure AD began to pick up the new metadata and stopped trusting tokens/assertions signed with the key that was removed. At that point, end-users were no longer able to access those applications.
Next Steps: We understand how incredibly impactful and unacceptable this is and apologize deeply. We are continuously taking steps to improve the Microsoft Azure Platform and our processes to help ensure such incidents do not occur in the future.
