Fix SharePoint Online PDFs Not Opening in Adobe Document Cloud
Question details
Users are unable to open PDF files using the Adobe Document Cloud integration in SharePoint Online, as files continuously open in the default SharePoint preview.

- Product
- SharePoint Online, Adobe Document Cloud
- Device & OS
- not provided
- Scenario
- Attempting to open and view PDF files in SharePoint Online using the integrated Adobe Document Cloud viewer.
- Observed behavior
- PDF files default to the native SharePoint preview window instead of Adobe Document Cloud, despite clearing caches, checking Azure AD permissions, and waiting for deployment.
Ensure you have administrative access to both the Microsoft 365 Admin Center and the Adobe Admin Console to verify app deployments and license assignments.
Verify Adobe Entitlements and Clear Session Data
Confirm that users are properly licensed for Adobe Document Cloud and force a clean session connection between Microsoft 365 and Adobe services.
Often, integration failures happen because the required licenses are not properly assigned in the Adobe Admin Console or old session cookies are forcing SharePoint to use its default behavior.
Log into the Adobe Admin Console and ensure the affected users are actively assigned the required Adobe Acrobat or Document Cloud licenses.
Go to the Microsoft 365 Admin Center, navigate to Settings > Integrated apps, and confirm the Adobe Document Cloud application is fully deployed to the correct user group.
Instruct affected users to go to their browser settings and clear their cache, specifically focusing on clearing all Adobe and Microsoft 365 session cookies.
Have users sign out of all active Microsoft 365 and Adobe accounts, restart their web browser, and sign back in to establish a fresh connection.

Escalate to Adobe Support with Diagnostics
If the integration still fails after verifying settings, collect necessary tenant data and contact Adobe Support for advanced troubleshooting.

Frequently Asked Questions
Why do my SharePoint PDFs keep opening in the default previewer instead of Adobe?
This typically happens if the Adobe Document Cloud integration is not fully propagated in your Microsoft 365 tenant, if the user lacks the proper Adobe license, or if the user's browser has cached the default SharePoint document handler.
Do all users need an Adobe license to view PDFs in SharePoint?
Yes, to utilize the Adobe Document Cloud integration features within SharePoint Online, users must have the appropriate Adobe Acrobat or Document Cloud entitlements assigned by an administrator.
How long does it take for the Adobe SharePoint integration to take effect?
App deployments in Microsoft 365 and SharePoint Online can sometimes take up to 24 hours to fully propagate across the tenant and reflect for all end users.
What web browsers are supported for the Adobe Document Cloud integration?
The integration is fully supported on modern browsers like Microsoft Edge, Google Chrome, Mozilla Firefox, and Safari. Always ensure your browser is updated to the latest version for the best compatibility.
