Hundreds of Microsoft Teams users across the UK reported problems this morning, with many saying they could not properly use video or audio calls. Downdetector data showed the disruption beginning at around 9:30am and easing later in the morning.
More than 300 people had logged issues by around 10am, and Downdetector showed 359 reports shortly after that. By 10:30am, at least 320 users had flagged problems, before reports started to ease from 10:40am. As of 10:50am, 65 users were still facing issues with the platform.
The biggest share of complaints involved audio quality, which made up 42% of reports. App issues accounted for 28%, while video quality made up 22%. Those figures point to a broad disruption rather than a single isolated fault, and they left users struggling to connect, speak and stay in meetings.
The reports were spread across the UK, with the largest concentration coming from London and Manchester. Users in Bournemouth, Bristol and Cardiff were also affected, along with people in Sheffield, Birmingham, Nottingham, Leicester and Luton. Downdetector was the main tracker for the outage, and its map showed the problem reaching multiple cities at once.
Microsoft Teams has become a default workplace tool for meetings, calls and day-to-day communication, so even a short disruption can interrupt work quickly. The pattern seen on Downdetector also mirrors other recent service complaints, including the outage that left thousands asking whether Claude was down. The unanswered question now is whether Microsoft can keep the issue from returning as the day goes on.
