Here is what some users are doing:
- Checkout a document from SharePoint
- Edit the document in Office (e.g. Excel or PowerPoint)
- Save the document.
- Check-in the document
The document library is versioned, so SharePoint creates a new version of the document. However, when the users open up the document again, the changes they made are not there. It is as if they just uploaded a copy of the previous version. What could be casuing this, and how can we fix it?
Other details:
- Approval is required on the list, but all users editing documents have the ability to see documents in the draft state.
- It seems to only happen to certain users on certain documents
If you’ve enabled “Only users who can edit items” for “Who should see the draft items in this document library”, users without edit item permission cannot see the updated version of the document until the major version has been published.
It turns out somebody in our organization messed something up in the Microsoft Project 2003 installation file, so anybody with Project 2003 had this bug. That installation file must have changed a DLL, modified permissions, or did something to mess up shared components with other Microsoft Office applications. I had no idea that installing Project 2003 could actually prevent somebody from saving a document from Microsoft Word into SharePoint, but it can.
