A family of Microsoft word processing software products for creating web, email, and print documents.
Hi,
Sorry for the inconvenience the problem caused for you.
Based on your description, when you try to share Word files within Word application, an error "unable to prepare file for sharing" will occur after updating Office app. I tested it on my side, there was no problem.
You can try to fix Office client, by performing a repair. Try a quick repair first, and if that doesn't work, try the online repair.
If the problem persists, could you please provide some information for me?
- Please provide a screenshot of your Word version(open PowerPoint > File > Account > capture a screenshot of the full Product Information column)
- If you click the "Share" button in the ribbon, will the same error occur?
- If you go to your OneDrive Online to share the file, can you share it successfully?
- Does the problem happen on other Office applications, such as: PowerPoint, Excel?
Best regards,
Jazlyn
