The issue with creating a Course Catalog on a new Tenant

For security reasons, Microsoft has disabled Azure Access Control (ACS) only for new Office 365 tenants by default. This prevents the creation of new catalogs that use an ACS app-only approach to handle permissions on the site collection only. In this case, you receive a SharePoint Online authorization issue "Token type is not allowed".
To enable this feature, you need to connect to SharePoint using Windows PowerShell and then run Set-SPOTenant -DisableCustomAppAuthentication $false.

Run the following commands on PowerShell:

Install-Module -Name Microsoft.Online.SharePoint.PowerShell

$orgName="<name of your Office 365 organization, example: contosotoycompany>"

Connect-SPOService -Url https://$

Set-SPOTenant -DisableCustomAppAuthentication $false

Please note:

  • Fill in the values for the $orgName variable (replacing all the text between the quotes, including the < and > characters).

  • When prompted with the Windows PowerShell credential request dialog box, type the login/password for the SharePoint admin account.
