Ensure Taxonomy Feature In SharePoint site connected to a Private/Shared Channel Sites

Taxonomy feature is not activated by default in SharePoint sites linked to a private or shared Teams Channels. When attempting to add content types with managed metadata columns, you may encounter an error message stating “Taxonomy disabled”.

To resolve this issue, you can enable the taxonomy feature with the ID 73ef14b1-13a9-416b-a9b5-ececa2b0604c using the PowerShell cmdlet Enable-PnPFeature before adding the content types to the sites with the template TEAMCHANNEL#1.

    $siteUrl = <Teams Channel SharePoint Url>
    $FeatureTaxonomy = "73ef14b1-13a9-416b-a9b5-ececa2b0604c" #enabled taxonomy

    Connect-PnPOnline -Url $siteUrl -Interactive
    Enable-PnPFeature -Identity $FeatureTaxonomy -Scope Site -Force
    # Add content types

    $list = New-Object Collections.Generic.List[string]
    $list.Add('0x0101AABBCCDDEEFF00112233445566778899AABB')
    $list.Add('0x0101FFEEDDCCBBAA99887766554433221100FFE')

    Add-PnPContentTypesFromContentTypeHub -ContentTypes $list -ErrorAction Continue

The MS Graph beta endpoint https://graph.microsoft.com/beta/teams/{team-id}/channels?$filter=membershipType eq ‘private’ can be used to find the SP Url of the private channel via the property filesFolderWebUrl made up of the SP url and folder url. Refer to How can I obtain the Sharepoint Site URL of the private channel from the Teams Graph REST API.
