Microsoft confirmed early Wednesday that customers may have been unable to use multiple Microsoft Teams features, then said its monitoring showed the problem was largely under control.

The latest customer note, posted at 7:26 a.m. IST on August 26, 2026, said the company would continue monitoring the service for the next 15 to 30 minutes to ensure the fault did not return.

The advisory is the kind of short, high-impact collaboration outage that immediately shows up in help-desk queues, missed stand-ups, and delayed incident bridges.

Teams Outage – Meetings Failed First

Microsoft 365 users may have trouble using several features in Microsoft Teams. Some users reported issues joining and creating Teams meetings, which aligns with these complaints.

ITmedia reported that Japanese users began posting shortly after 9:00 a.m. local time that they could not enter meetings, and that some who did get in could not share screens. “Teams” trended on X, while some people said one-to-one calls still worked, a split that usually points to a meeting-service problem rather than a total client collapse.

That distinction matters for security teams. When join, create, and in-meeting tools fail together, tabletop exercises stall and on-call engineers lose the channel they expected to use.

Organizations that treat Teams as the default emergency path should treat this as a continuity event, not only a productivity glitch. A full client restart, a switch from desktop to web or mobile, or a fallback conference bridge is more useful during a live vendor incident than chasing a local policy change.

Microsoft 365 Status issued a tight sequence of updates at 6:56 a.m., 7:11 a.m., and 7:26 a.m. IST. The last of those said monitoring indicated the issue was largely mitigated and that engineers would continue watching for 15 to 30 minutes to prevent a recurrence.

The Microsoft 365 Status account on X pointed administrators to the same advisory. Microsoft did not include a detailed public root-cause explanation in that latest customer-facing note, and no incident ID was quoted in the information available at the time of writing.

We have determined that maintenance related activity had unintended impact on the Microsoft Teams service and resulted in degraded functionality for users in Asia-Pacific. We have halted the maintenance activity and our service has returned to standard availability levels.…

Microsoft Teams is operational after the morning disruption, with only a handful of user-submitted reports over the previous 24 hours and the outage marked resolved. A short watch window still leaves room for a relapse, which is why Microsoft’s wording stayed at “largely mitigated” instead of “service restored.”

This was not an isolated Teams week. Microsoft only recently closed a screensharing video-quality degradation, and a separate advisory still warns that some shared-channel “Copy Link” URLs are malformed after an update meant to improve link generation. ITmedia also noted that Teams meetings and calls in the Asia-Pacific region failed on July 24.

Cyber Security News separately documented a Microsoft 365 network incident days earlier that interrupted Teams along with SharePoint, OneDrive, and Copilot for customers whose traffic crossed North America, and a later South America degradation that again hit multiple suite services at once.

Until Microsoft closes the advisory, administrators should watch the Microsoft 365 admin center service-health blade and confirm that meeting create and join work on desktop, web, and mobile.

Log any SOC huddle or tabletop that could not start because Teams was down, and keep a secondary bridge in the incident runbook. Users who are still blocked should retry after a full quit and relaunch rather than assuming a tenant misconfiguration while the vendor is still in a post-mitigation watch.

If the 15-to-30-minute window ends without a replication, the advisory should move from mitigated to restored. If symptoms return, the same status page and the Microsoft 365 Status account will be the first official signal.
