Solution 1Recommended

Reset the Co-Authoring Setting via PowerShell

Use PowerShell to explicitly disable the co-authoring setting on the backend before re-enabling it through the portal interface.

Sometimes the portal UI gets out of sync with backend policies. Manually turning off the feature using PowerShell clears the synchronization error, allowing you to successfully enable it again.

1
Open PowerShell as Administrator

Search for PowerShell in your Windows Start menu, right-click the application, and select Run as administrator.

2
Connect to Security & Compliance

Type the command Connect-IPPSSession and press Enter to connect your PowerShell session to the Microsoft Purview environment.

3
Disable Co-Authoring for the Policy

Run the command: Set-LabelPolicy -Identity <policy name> -DisableCoauth $true (make sure to replace <policy name> with the actual name of your label policy).

4
Re-enable in the Compliance Portal

After the command successfully executes, return to your web browser, navigate to the Compliance portal, and try enabling co-authoring again.

Evaluate Policy Impact: Disabling this setting may temporarily affect how labeled content is handled in OneDrive and SharePoint. Review potential consequences with your team before proceeding.

Frequently Asked Questions

What is the Connect-IPPSSession command used for?

Connect-IPPSSession is a PowerShell cmdlet that connects your local shell to the Security & Compliance Center in Microsoft 365. It allows administrators to run backend configuration commands for Microsoft Purview.

Why does the Compliance portal fail to enable co-authoring?

This usually happens due to a backend synchronization glitch between the UI and the server policies. Disabling the policy forcefully via PowerShell acts as a reset, clearing the blockage so the UI can enable it properly.

What should I do if I don't have PowerShell admin rights?

If you do not have administrative privileges on your machine or global admin rights in Microsoft 365, you will need to contact your organization's IT department or Microsoft 365 administrator to run the commands or submit a support ticket on your behalf.
