Updated on Thursday, Nov. 12 at 12:37 p.m. ET — As of this writing, users in multiple regions are still having trouble accessing Microsoft 365.
Microsoft's latest update to users, posted to X, states, "We determined the elevated load isn't driven by an increase in traffic, but by a number of servers being unexpectedly unavailable; straining the remaining infrastructure. We're working to safely return them to service."
Updated on Thursday, Nov. 12 at 2:29 p.m. ET — According to the latest update on the Microsoft service health status webpage, users may have trouble accessing Microsoft Exchange Online, Microsoft Teams, SharePoint Online, Microsoft Copilot 365, and Microsoft Defender XDR.
The status page stated that the current issues affect Microsoft 365 business and enterprise customers, not Microsoft's consumer tech products.
"We're aggressively pursuing all pathways to reduce impact," the company wrote in an update to users. "As a precaution, we've paused all deployments and configuration changes while we review recent changes for any correlation to this event. We've also moved traffic for some services off the affected infrastructure to further reduce load, with additional traffic moves in progress."
Microsoft customers are reporting problems accessing a variety of the company's software products and services on Thursday afternoon.
What services are affected by the ongoing Microsoft outage?
Downdetector shows sharply elevated reports of problems for the following Microsoft services:
Microsoft Teams
Microsoft Outlook
Microsoft Copilot AI
Microsoft 365
Microsoft Azure
Microsoft Store
The company acknowledged an outage through its Microsoft 365 Status account on X:
This Tweet is currently unavailable. It might be loading or has been removed.
While the initial update indicated the outage was impacting email inboxes "in the Americas," later updates confirmed that other regions and products were also being impacted.
An update posted at 1:07 p.m. ET stated: "We've confirmed the issue may affect Microsoft 365 service connectivity for users in any region, more information will be provided in the Microsoft 365 admin center under EX1550543." The company added, "We've begun redistributing connection traffic across our broader worldwide infrastructure to help balance the load."
The problem was so severe that some customers may not be able to access the Microsoft 365 admin center, as the company wrote on X users should instead refer to the Microsoft service status webpage. However, this page was also down for part of the day, according to multiple Mashable reporters.
Mashable contacted Microsoft with questions about the outage, and we'll update this story if we receive a response.
