Warning: The retired, out-of-support Internet Explorer 11 desktop application has been permanently disabled through a Microsoft Edge update on certain versions of Windows 10. For more information, see Internet Explorer 11 desktop app retirement FAQ.
Symptoms
Consider the following scenario:
-
You have Microsoft Office applications and Internet Explorer 10 installed on a computer.
-
You browse a website by using Internet Explorer 10, click a link, and then click Open to open an Office file that is stored on a server.
-
After the file is opened by the corresponding Office application on the computer, you edit the file and then save the changes.
-
You open the same file by clicking the link on the website.
In this scenario, the changes that you made may not be saved.
Cause
This issue occurs because temporary Internet files are cleaned up by the system.
A file is saved as a temporary Internet file when you click Open to open the file. If the file is served with a Content-Disposition:attachment header, the Read-only attribute is not set on the file. Then, a corresponding Office application opens the file from the Temporary Internet Files folder. The changes that you made are saved to the file that is located in the Temporary Internet Files folder. However, the temporary Internet files are periodically cleaned up by the system. Therefore, the file that contains the changes may be deleted.
Note If a server does not send the Content-Disposition:attachment header together with the file, the Read-only attribute is set on the file, and the issue does not occur.
