Sharepoint Open in Application

Gaetan_France 

Hello,

I understand the challenge you're facing with opening non-Microsoft files like PDFs from your SharePoint drive in their respective local applications, especially since you’ve mentioned the volume of data makes OneDrive replication unfeasible.

Unfortunately, SharePoint’s native “Open in app” feature is primarily designed for Microsoft Office files (e.g., Word, Excel, PowerPoint). For non-Microsoft files, like PDFs, the default behavior is to open them in the browser, as you've noticed.

That said, here are a few potential workarounds:
1. Browser Settings
2. Adobe Integration
3. Mapped Network Drive
4. Power Automate

Unfortunately, there is no built-in feature to extend “Open in apps” to non-Microsoft files in SharePoint Online, but these workarounds may help with your specific needs.

I hope this provides a helpful solution, and if you need further assistance or details on any of these approaches, feel free to reach out.
