We are creating teams channels with the MS teams Zap (Zapier App installed in those Teams).  This worked well with the create channel action.  However, very soon we are seeing this error retuned by Zapier:

Error. Maximum number of default channels reached

 

I have looked into this and it appears that it may be caused by the teams being created with the favourite flag as true which forces them to appear to users (show option) and you can only have 10 on show at any one time.  I have gone into the channels, as the Zap user,  to hide all current channels, but this error is still appearing.

I also tried using the API to create a channel (using PAI Request Beta for MS Team Zap), but that returns a 405:Unknown Error from the server.  Other Chat related API calls (both post and get) have worked well through this beta tool.

 

Has anyone else seen this issue and know how to work around it?

Hi @AshleyMorris 

Good question.

Can you post screenshots with how your Zap steps are configured to give us more context?

HI, 

 

Not sure how much info you need as the zap action is only a single item.  Here is a screen of the zap doing the request:
 


As above, this all worked fine, until I started getting the error from with the statement about 10/10 default channels.  I tested without any description and got the same result. 

The API test, returned a 405 error.  This was done using a cut and past of the example on the MS WebSite

I tested with isFavoriteByDefault = False and True, or not present, in the JSON, with no change in results. Still a 405 error.

You may want to try opening a ticket with Zapier Support: https://zapier.com/app/get-help

I just the Zapier AI tool to troubleshoot and it gave me this:

 

The error message you’re seeing is due to a limitation in Microsoft Teams. Each team in Microsoft Teams can have up to 200 channels, but only 10 of them can be default channels. It seems like you’ve reached the maximum limit of default channels for the team you’re trying to create a channel in.

To resolve this issue, you can either delete some of the existing default channels in the team or create the new channel as a non-default channel. If you choose to delete some channels, you can do this directly in Microsoft Teams. If you want to create the new channel as a non-default one, you’ll need to adjust the settings in your Zap step. Unfortunately, Zapier currently does not support creating non-default channels in Microsoft Teams. You might need to create the channel manually in Teams or use another automation tool that supports this feature.

 

If Support can see this; can I request an enhancement, as this make this Zap to create Channels in Teams next to useless!

Best to submit a ticket to Zapier Support with this feedback/feature request for it to be properly logged.
