A repeating Reconnecting message usually means Microsoft Teams cannot maintain its session with Microsoft’s service. Check whether ordinary websites load, compare the Teams web app with the desktop or mobile app, and confirm whether coworkers have the same problem before clearing data or reinstalling anything.
Find out whether the problem is local or widespread
Open two unrelated websites and another internet app. If everything is offline or unstable, fix the network first. If Teams fails for several coworkers at the same time, an organisation or Microsoft service incident is more likely than a damaged app on your laptop.
Try teams.microsoft.com in a supported browser. If the web version works while the desktop app reconnects, focus on the app, sign-in session, or local cache. If both fail only on one network, a VPN, proxy, firewall, DNS filter, or captive Wi-Fi login page may be interrupting the connection.
Sign out and close Teams completely
Select your profile picture, sign out, and close Teams. On a computer, confirm the app is no longer running in the taskbar, menu bar, or background process list before opening it again. Sign in with the correct work, school, or personal account.
If your password was recently changed, complete any new multi-factor authentication prompt in the normal Microsoft sign-in window. Do not approve an unexpected prompt or give an OTP to someone claiming to repair Teams.
Compare Wi-Fi, Ethernet, and a temporary hotspot
If practical, move nearer the router or use Ethernet. A phone hotspot can be a short diagnostic: if Teams immediately works there, the original Wi-Fi or ISP path needs attention. Stop the test after a minute if mobile data is expensive, and do not use a personal hotspot for confidential work if company policy forbids it.
Pause a VPN briefly only if your organisation permits it, then reconnect. Some workplaces require Teams traffic to pass through managed security controls, so changing network settings may make the problem worse. Record the time and exact message before contacting IT.
Clear the cache only after simpler checks
Microsoft’s official reconnect guide recommends clearing the Teams cache when sign-out and connection checks do not help. The exact location and reset method vary between the current Teams app, operating system, and managed installations. Follow Microsoft’s linked instructions for your version rather than deleting similarly named folders at random.
Clearing a local cache should not delete server-stored Teams conversations, but it can remove local thumbnails, icons, display data, and other cached items. If you are unsure, use the safer sequence in how to clear an app cache safely.
Update or reinstall the app
Install pending Teams and operating-system updates, restart the device, and test again. If only the desktop app remains broken, uninstall Teams using the operating system’s normal app controls and reinstall it from Microsoft’s official site or your organisation’s software portal.
Do not download a Teams installer from an advertisement or third-party software site. A managed work computer may require IT to deploy the correct version and security configuration.
Collect useful details for support
Note whether the problem affects chat, meetings, or the entire app; the device and operating system; whether the web version works; the networks tested; and the time the reconnect loop began. Microsoft directs employees to their IT administrator as the first support contact because administrators can see organisation settings and incident information.
If Teams reconnects only when starting a meeting, also check its camera and microphone permissions. For camera-specific problems, use the Teams camera troubleshooting guide.
