We can’t add SharePoint subsite document libraries in the latest Adobe Reader. Top‑level sites work, but subsites return ‘access denied’ despite correct permissions. Others report this issue since around Aug 2025. Any solution?

Hi @dekidejan,

Hope you are doing well. Sorry for the trouble with using Sharepoint with Acrobat.

Adobe introduced modern OAuth-based SharePoint integration starting Aug 2025. This rollout is still phased and inconsistent, and does not handle all SharePoint URL types equally.

More info here: Access your SharePoint files in Acrobat, Acrobat Reader

• As a result:

  • Top-level site collections work

  • Subsites / nested document libraries often fail with “Access Denied”

Additionally, Acrobat requires exact document library URLs + proper app permissions, not just site-level access. Even with correct user permissions, the integration can fail due to authentication scope or API limitations, not SharePoint permissions. More info: Adding SharePoint site as Adobe Acrobat storage fails - Microsoft Q&A

This is what you can try:

Grant Admin Consent in Azure (critical for subsites)

Subsites often fail because API permissions are not fully granted. Steps:

1. Go to Azure Portal > Entra ID > Enterprise Applications

2. Search for Adobe Acrobat / Adobe Document Cloud

3. Open > Permissions

4. Click Grant Admin Consent

Without this, Acrobat may authenticate but still fail to access deeper site structures.

Hope this gives some clarity.

Souvik
