Signing out and signing back in refreshes your authentication tokens and resolves federated credential conflicts causing the freeze.

Often, the freezing issue occurs because the background authentication token for Adobe Acrobat has become invalid or expired. Manually forcing a sign-out clears the stalled session.

Open the Integrated Viewer

2
Access the Menu

Click on the user profile or menu icon located in the upper-right corner of the Acrobat viewer.

Frequently Asked Questions

Why does Adobe Acrobat freeze on a spinning circle in SharePoint?

This typically happens when your federated sign-in credentials or authentication tokens become invalid or expire. The integration stalls in a loading loop while failing to verify your license.

Does this issue affect users who have the same enterprise license?

Yes. Even if multiple users share the identical enterprise license tier, individual authentication tokens expire or conflict locally, meaning the freezing issue can affect specific users randomly.

Can I merge PDFs outside of SharePoint to avoid this freeze?

Absolutely. You can download the necessary files to your local device and use a desktop PDF editor like WPS Office to merge them without relying on active web authentication.

How do I know if my authentication token has expired?

Usually, an expired token will automatically trigger a new sign-in prompt. If this prompt fails to appear due to a browser or integration glitch, the system freezes, requiring you to manually sign out and sign back in.
