Start Provisioning of private channel site

Hi Team,

I am having below scenarios looks like it is the same issue for me as well.

• Created a team via Graph API.
• Created Channel associated with team.
• Start conversations by members into channel
• now I want to archive the channel by teamId and channel ID:
• To Archive channel I am using below URL:
• URL: https://graph.microsoft.com/v1.0/teams/<team-id>/channels/<channel-id>/archive
• Request Method: POST
• Request Body: { "shouldSetSpoSiteReadOnlyForMembers": true }
• But I am getting below error:
  { "error": { "code": "BadRequest", "message": "Could not update Sharepoint folder permissions / archival state because the channel site url is not available.", "innerError": { "code": "Unknown", "message": "Could not update Sharepoint folder permissions / archival state because the channel site url is not available.", "date": "2025-08-06T16:35:02", "request-id": "2987b9a3-e515-46a2-8925-240e6825f362", "client-request-id": "2987b9a3-e515-46a2-8925-240e6825f362" } } }
• If I do manual click on file and after provision the folder, if running same archive request it's getting success. Could you please guide me how can I achieve this by code , not by manual asking user to click on File tab under channel.

Same issue here.

Calling the FilesFolder using Graph API (https://dori-uw-1.kuma-moon.com/en-us/graph/api/channel-get-filesfolder?view=graph-rest-1.0&tabs=http) doesn't start the private channel SharePoint site provisionning.

I've been trying for more than one hour (every 120 sec) and nothing happens.

As per July 22, 2025 this workaround is not valid anymore, or maybe it has been blocked.

Hi System,

Thanks for reaching out on Microsoft Q&A!

Normally, a site for a private channel is only provisioned as soon as one clicks the ‘Files’ tab. Basically the same behaviour applies to a channel folder in ‘standard’ channels.

However, when it comes to API calls, clicking the ‘Files’ tab isn’t something you can do. But, there is a possibility to mimic this by calling the ‘filesFolder’ API after you’ve created the private channel, triggering provisioning of the site.

Please find the details for the ‘filesFolder’ API through the link below:
