Latest Message<\/th>\nTitle: Some users in the United States may be intermittently unable to access some Microsoft 365 services<\/p>\n

User impact: Users in the United States may have been intermittently unable to access some Microsoft 365 services.<\/p>\n

More info: The following services may have been impacted:
– Exchange Online
– Microsoft Teams<\/p>\n

Final status: We’ve confirmed that the service remains healthy after manually reinstating the entire network infrastructure that was slated for active service load and impact is remediated.<\/p>\n

Scope of impact: Some users in the United States may have been intermittently unable to access some Microsoft 365 services.<\/p>\n

Start time: Wednesday, March 18, 2026, at 2:00 PM UTC<\/p>\n

End time: Wednesday, March 18, 2026, at 3:08 PM UTC<\/p>\n

Root cause: A portion of networking infrastructure, slated for reinstatement to active service, had been only partially reinstated, which led to load balancing issues when handling service traffic.<\/p>\n

Next steps:
– We’re continuing our investigation into the partial reinstatement to better understand why this has occurred so we can determine how we can best avoid similar issues in the future.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
