November 2, 2016 - https://www.reddit.com/r/MicrosoftTeams/s/XdeeSgeNcM · It happened again today for no apparent reason and just like before was resolved by uninstalling and reinstalling the application. How can I troubleshoot in more detail why this is occurring? I don't know if there are logs stored anywhere but if there are I'm happy to look? ... Need some help with tracking down an issue with a 3rd party app deployment to Teams.

r/sysadmin on Reddit: Teams outage this morning
January 26, 2024 -

Starting just a short while ago, we started seeing the following behaviors in Teams:

  • Delayed responses

  • Web app showing only old chats

  • Photos not loading

  • Can't hide some chats

As I sent a notice to everyone, Microsoft created an incident on this: https://imgur.com/a/JSaHi91

Some users may experience multiple issues with their Microsoft Teams

r/sysadmin on Reddit: Microsoft Completely Down?
March 3, 2025 -

Hello, my fellow sysadmins. Anyone else having a fun time with Microsoft Services right now? I know they were having issues with Outlook over the weekend, but it's looking like everything is inaccessible i.e, Team, Outlook, even their Service Status Center. Anyone else affected by this?

Edit: We're located in Canada.

Edit #2: The Issue looks to be an ISP issue with Rogers routing to Microsoft here, specifically in Canada.

Edit #3: It looks like things are coming back "online" in Canada. Current Status from Microsoft:

Issue IDMO1022159

"We're investigating user reports of issues accessing various Microsoft 365 services. We've detected a potential authentication token problem, and we're further examining this pathway to confirm it as the cause of impact and determine our next troubleshooting steps."

Looks like http://office.microsoft.com/, Microsoft.com, and Entra sites are all down for the UK and I can access a UK based VM in Azure and that's seeing the same problems...

Oh... and Azure? Or is it the same issue?
https://www.theregister.com/2025/10/29/aws_us_east_1_more_problems/?td=rt-3a

Yes could be Azure US-EAST-1
https://www.tomshardware.com/news/live/aws-outage-strikes-again-colossal-internet-breakdown-strikes-again

Hmmm our VMs are running in Azure but the portal isn't, Microsoft Graph is running in the backend, but the Entra admin center is not.

UPDATE:
Starting at approximately 16:00 UTC, we began experiencing DNS issues resulting in availability degradation of some services. Customers may experience issues accessing the Azure Portal. We have taken action that is expected to address the portal access issues here shortly. We are actively investigating the underlying issue and additional mitigation actions. More information will be provided within 60 minutes or sooner.

It's a new day and the clock has been reset... 0 days since outage.

We didn't have any problems with out site yesterday which is on Azure so quite happy with that probably because we use hosted VMs that weren't affected.

January 25, 2008 - There seems to be a pattern at Microsoft that has become impossible to ignore. It's a cycle we've seen too many times: Build something bold. Undermine it from within. Watch it collapse, and pretend it was part of the plan. This time, its Xbox who has writing on it walls... We saw it with Windows Live Messenger - quietly killed and replaced by products that never had its heart. We saw it with Skype - once a world-dominating verb, now a ghost of lag and bloat. We endure Teams - a Frankenstein forced upon us by mandates, not merit.

Is anyone else experiencing weird issues with O365 today? Microsoft shows a health status for Microsoft Teams. We are seeing a lag in Exchange Online emails (about 10-15 minutes from hitting send, to when it actually sends).

r/sysadmin on Reddit: Teams Machine wide installer and “Microsoft Teams Heap Buffer Overflow Vulnerability (Sep 2023)”
3 days ago -

We need to mitigate the flagged in our vulnerability scans.

After tracing the affected files, we found they reside in the Teams folder under the user’s AppData. Further investigation showed this folder is left behind from previous Teams updates—the Teams installer does not fully clean up old versions.

The source of the issue was the Teams Machine-Wide Installer. Actions taken so far:

  1. Removed the Teams Machine-Wide Installer via an Intune script

  2. Disabled Teams in the Office 365 app deployment in Intune

  3. Currently deleting the leftover Teams AppData folders

  4. Created a new Teams deployment via the Microsoft Store (new method) – not yet deployed

Despite this, the vulnerability continues to reappear, and more devices are now being flagged.

Questions:

  1. How can we prevent future Teams installations from recreating the AppData Teams folder?

  2. Is deploying Teams via the Microsoft Store the correct long-term approach?

  3. Why is Microsoft Teams installation/uninstallation so inconsistent and difficult to manage?

Thanks
