Error Solution for 'Must Have Manage Web Site Permissions Or Be A Tenant Admin In Order To Add Or Remove Sites From The Site Collection App Catalog Allow List'

Introduction

Recently, I was trying to create Site Collection App Catalogue on SharePoint Online through PowerShell, below are the commands that I used:

Connect-SPOService -Url https://Domain-admin.sharepoint.com/ -credential [email protected]
$site = Get-SPOSite https://Domain.sharepoint.com/sites/IMS
Add-SPOSiteCollectionAppCatalog -Site $site

Then I got the below error.

I am the SharePoint Tenant Admin, but then I also came across the article, where it was written that the user was trying to create an App for Site Collection must be a Site Collection Administrator for the Tenant Site Collection App Catalogue.

I made myself the Site Collection Administrator and I was able to create App Catalogue for Site Collection.

The User Rights necessary for creating an App Catalogue for Site are as follow:

- User must be a SharePoint Tenant Admin.

- User must be a Site Collection Administrator for Tenant Site Collection App Catalogue.
