Created a task from the Chat. I did not know it would mess up the post in chat. I can't reverse

Question

I created the task, and then it messed up the chat for the rest of the team. So I delted the task, but the chat is still screwed up. If that is not reversible, this is a bad move MS.

Also in the process I somehow deleted myself from the team.

Hi @Jerry Shelton,

Good day. It’s clear this hasn’t been the smoothest experience, and your concern is heard.

Creating a task from a chat should not normally leave the conversation in a broken state after the task is deleted. To help me better understand what’s happening in your case, could you please clarify the following:

Do other team members also see the same “messed up” behavior in that chat?

Was this a standard Teams channel conversation, or a group/private chat?

In the meantime, here are a few things you can try on your side:

---

1/ Confirm team membership and role

It would be helpful to have a team owner confirm that you’ve been fully re‑added to the team and that your role (Member vs Owner) is correctly set. Membership changes can sometimes affect how chat state appears.

2/ Use Teams on the web

Please check the same chat using Teams on the web

If the chat appears normal on the web but not in the desktop app, this may point to a local client or sync issue rather than a service‑side problem.

3/ Clear the Teams cache

• Quit Teams completely (Quit).
• Press Win + R, enter the following path, and then select OK: %userprofile%\AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams
• Delete all contents inside the MSTeams folder.
• Restart Teams.

4/ Uninstall and reinstall Teams

To uninstall Teams, you need to uninstall two items. Follow the steps below to fully uninstall Teams.

Quit Teams by right-clicking the Teams icon in the taskbar and choosing Close window.

In Windows, click on the Start button > Settings > Apps.

Under Apps & features, search "teams".

Highlight Microsoft Teams, then select Uninstall.

A box will appear, then again select Uninstall to confirm. A new box will appear, asking "Do you want to allow this app to make changes to your device?" > Select "Yes".

• Now select Teams Machine-Wide Installer, click Uninstall. Then follow the same process described in the previous step.

Now you can reinstall Teams via this link: Download Teams Desktop and Mobile Apps | Microsoft Teams

5/ Contact Microsoft support:

If the issue persists after trying the steps above, the best next step would be to have your IT administrator open a support ticket with Microsoft via the admin center. A technical support engineer can then initiate a remote session, review backend settings, and run diagnostics. If needed, they can escalate the case to specialized engineering teams who are well-equipped to perform advanced troubleshooting and provide targeted solutions.
