Add-SPOOrgAssetsLibrary : Attempted to perform an unauthorized operation

Question

I need your help. I am trying to create an assets library and always get the following error:

Add-SPOOrgAssetsLibrary : Attempted to perform an unauthorized operation.

I am already registered as site admin and everyone except external users has read permission, I just don't know what to do. Does anyone know what to do?

Answer 1

You have to use an account with Global Administrator or SharePoint Administrator role in Microsoft 365 to create an organization assets library in your SharePoint tenant.

Check this documentation for learning more about these roles: About the SharePoint Administrator role in Microsoft 365.

Only site admin / site collection administrator (SCA) permissions are not enough for creating an organization assets library.
