File Handler
3 TopicsPersistent OneDrive File Handler Cache After Removal
I’m a developer supporting an Azure AD application that was previously registered with a File Handler for PDF files (used to display the "Open with Lumin PDF" option in OneDrive’s context menu). The File Handler configuration was removed on June 19, 2024. However, some of our customers are still seeing the "Open with Lumin PDF" option in their OneDrive UI. This is causing confusion and additional support overhead on our side. I understand this is likely a caching issue, so I’ve asked our customers to: Clear the server-side cache by following https://learn.microsoft.com/en-us/onedrive/developer/file-handlers/reset-cache?view=odsp-graph-online Clear their browser cache, re sign-in in a new browser profile I’ve already tried all possible solutions within my control to resolve this caching issue, but none have been effective. What else can I do to address this?77Views2likes1CommentCreate a SaaS Offer for FileHandler App registration confirmation
Recently I have researched to develop FileHandler Add-In in App registration. I want to publish a SaaS offering to the marketplace (App Source) for my app registration. Or at least we can publish it to gallery Microsoft Entra Gallery. But, I see that Microsoft isn't onboarding new applications to Microsoft Entra gallery in FY25 (Ref: https://learn.microsoft.com/en-us/entra/identity/enterprise-apps/v2-howto-app-gallery-listing#submit-your-application) For publishing a SaaS offering, Does Microsoft allow us to publish a SaaS offering for App registration in 2024 and 2025? I didn't find any documentation about such restrictions like publishing to Microsoft Entra Gallery. Please help me confirm this.280Views0likes0CommentsChanging file extension in SharePoint behaviour when copying/moving file from different site
We are trying to modify the file extension in a document library in SharePoint. Our use case is to encrypt the file and change its extension to html. We are observing unexpected behavior when a file is being copied/moved from another site. In this case, certain SharePoint functionality is breaking such as FileHandler, etc. Refer the following screenshot for more details: Here, both files are converted into html but only the file that was uploaded is correctly detected by the FileHandler. Steps to reproduce: 1. Upload a docx file in any document library in Site1. 2. Move/Copy the docx file to a document library in Site2. 3. Upload a docx file in the document library in Site2. 4. Rename the docx file to html file using REST API. 5. Verify the behavior difference between both the files. Expected behaviour: There must be no difference in the behavior between uploaded files and moved/copied files. Queries: 1. This issue has been observed recently. Has something changed that might have caused this? 2. Is there any API to force change the type of the file.1.5KViews0likes1Comment
