We are pleased to announce that we worked with Adobe to improve access to PDF files. You can now open PDF files directly in Adobe Reader - and the PDF file will remain connected to SharePoint Online. You can also edit and save your changes to SharePoint Online from the desktop. And further, you can now use versioning (check-in and check-out) with PDF files for better management and review. We have improved the experience while maintaining the level of security you expect from Office 365.
To take advantage of this update, do the following steps.
This SharePoint Online update is currently being rolled out worldwide along with several other new features.
Thank you for your feedback and patience,
The SharePoint Online Team
