Product: Adobe Acrobat, Microsoft SharePoint
Device & OS: Windows
Scenario: Attempting to open, save, or sync PDF documents directly between Adobe Acrobat and a SharePoint library using the Microsoft Edge browser.
Observed behavior: Integration fails and Acrobat cannot connect to SharePoint because modern authentication cookies are blocked or not successfully created.

Before you start

Solution 1Recommended

Allow Legacy Authentication Apps in SharePoint Admin Center

Modify SharePoint access control policies to allow apps that do not use modern authentication, permitting Acrobat to connect directly.

Access the Admin Center

Navigate to Access Control

On the left sidebar, click on 'Policies' and then select 'Access Control'.

Adjust Authentication Policy

Click on 'Apps that do not use modern authentication'. Select the 'Allow' option and click 'OK' to save your changes.

Policy Application Delay: It may take a few hours for the updated SharePoint access control policies to propagate across your tenant.

Solution 2

Enable Modern Authentication in Acrobat via Registry

Force Adobe Acrobat to use modern authentication by adding a specific registry key.

Solution 3

Update WebView2 Runtime and Clear Credentials

Frequently Asked Questions

Will enabling 'Apps that do not use modern authentication' affect my overall SharePoint security?

Yes, allowing apps that do not use modern authentication can slightly lower your security posture by permitting legacy protocols. It is generally recommended to update the client applications to support modern authentication where possible.

How do I fix cookies being blocked for SharePoint in Windows?

You can unblock cookies by opening the Windows Control Panel, navigating to Internet Options > Privacy > Sites, typing in your SharePoint URL (e.g., yourcompany.sharepoint.com), clicking 'Allow', and then clicking 'OK'.
