Cannot create a channel in a team (Created one previously in that team)

I am a User Administrator for our account.

A couple of months ago, I created a team, and I was able to add channels. A week ago, I tried adding a new channel and got the error:

We're having trouble creating your channel. Please try again later.

I tried again later — I've been trying daily for the past week.

I have verified that I am still listed as an Owner of the team. As a User Administrator, I removed and re-added myself.

I created a new team and tried to add a channel there, again with that error message — in the freshly created team.

There are no deleted channels in either team. The name of the channel I've tried is "Blog" and "BlogDev" (I tried to see if I was hitting a secret reserved name).

I'm not sure what else to check. Thank you for any insight you can provide!

Hi @IsaacEilandHall-5194

Do you have the same issue in Teams web client?

Does anyone else have the same problem in your organization?

Hmm, thank you, I hadn't thought to try in the browser. It works there. Is there anything I can check for why it might not work from the app? I can use the browser as a workaround, of course.

Thanks for the reply, for sure! :)

If you could create a channel normally in Teams web client, I think this issue may related to your Teams client itself.

In this way, could you try to clear Teams client cache file to see if it could be fixed?

Awesome, that worked!

For anyone who finds this thread - I googled, but to boil it down:

Close Teams by right-clicking the taskbar icon and choosing "quit"

Start → Run → %appdata%\Microsoft\Teams

Delete the contents of that folder.

The article I found says to reboot, but I had success without that - just restarted Teams, signed in, and I could create channels again. :)

Yay!
