Usługa hostingu i synchronizacji plików firmy Microsoft.
Hello Maciek,
Thanks for reaching out to Microsoft Q&A forum Support.
I understand that the person you are sharing files with via OneDrive is unable to open them using the desktop app. This issue could be caused by several factors, such as permission settings, account conflicts, or other configuration problems.
I recommend trying the following troubleshooting steps:
1.Reshare the File with Edit Permissions
- Use OneDrive Web → Share → “Anyone with the link can edit”
- Or share directly to their Microsoft account email with “Can edit” enabled
- Ask the Recipient to Use the Same Account Across Apps
- Sign out of other Microsoft accounts
- Use the same account for OneDrive, Office, and browser login
- Try Opening in Microsoft Edge
- Some features like “Open in desktop app” work best in Edge
- Avoid Mixing Business and Personal Accounts
- If the recipient is using a business account, try sharing to their personal Microsoft account instead
Best wishes,
