Question details
The user needs to resolve a permission error encountered when trying to create an Office template library in SharePoint.

- Product
- SharePoint
- Device & OS
- not provided
- Scenario
- Creating an organization assets library for Microsoft Office templates using SharePoint and a PowerShell command.
- Observed behavior
- The system throws an error stating that the 'Everyone except external users' group must have read access to the document library before it can be registered.
Ensure you have SharePoint administrator or site owner privileges to modify document library permissions, as well as access to the SharePoint Online Management Shell.
Grant Read Access to Everyone Except External Users
Manually update the document library permissions to ensure all internal users can read the templates before running the registration command.
SharePoint requires organization asset libraries to be accessible to all internal employees. If the library inherits permissions that restrict access, the PowerShell command to register it will fail.
Navigate to your SharePoint site and open the specific document library intended for your Office templates. Click on the Settings gear icon in the top right corner, select 'Library settings', click 'More library settings', and then choose 'Permissions for this document library'.
If the library inherits permissions from the parent site, click the 'Stop Inheriting Permissions' button in the top ribbon. Confirm the prompt to allow custom permission assignments for this specific library.
Click 'Grant Permissions' in the ribbon. In the 'Invite people' dialogue box, type 'Everyone except external users'. Select 'Show options' and change the permission level to 'Read'. Click 'Share' to apply the changes.
Select 'Check Permissions' from the ribbon, type 'Everyone except external users' in the search box, and click 'Check Now'. Verify that the group explicitly shows 'Read' access.
Open the SharePoint Online Management Shell as an administrator and run your `Add-SPOOrgAssetsLibrary` PowerShell command again. The library should now successfully register as an organization assets library.

Frequently Asked Questions
Why does SharePoint require 'Everyone except external users' to have read access?
When you create an organization assets library, SharePoint must ensure that all internal employees in your tenant can actually view and utilize the Office templates stored within it. If this base permission is missing, the registration command will fail to prevent inaccessible templates.
What is the correct PowerShell command to add an organization assets library?
The standard command is `Add-SPOOrgAssetsLibrary -LibraryUrl <URL>`. You must execute this command using the SharePoint Online Management Shell with SharePoint administrator privileges.
Can I use a custom security group instead of 'Everyone except external users'?
No, the `Add-SPOOrgAssetsLibrary` command specifically validates the presence of the 'Everyone except external users' group. While you can add other custom groups alongside it, this specific group must maintain at least Read permission for the registration to succeed.
Where can I download the SharePoint Online Management Shell?
You can download the latest version of the SharePoint Online Management Shell directly from the official Microsoft Download Center. Once installed, search for it in your Windows Start menu and ensure you run it as an administrator.
