Premature time-out on Office documents

Question

I am on on-prem setup using ADFS, Office Online Server and SharePoint Server.

Screenshot taken from online, but is the same as what I am encountering.

I opened a Word document from SharePoint and was working on it with the Desktop Word app. While working on my Word document at around 40min mark, the error message "Upload Failed - You are required to sign in upload your changes to this location" appeared.

However, my session timeout and ADFS token expiration are set at 60min.

Shouldn't session hold till 60min? What other mechanism is at work that caused this error?

Is the Desktop Word app having other authentication method? If yes, what is it and what is default timeout and how to configure that?

Hi @Robin Chen ,

We can work together to narrow down and resolve the situation. This could be caused by several factors, such as network connectivity, Office application settings, or authentication methods. Here are some possible solutions that you can try:

• Check your network connection and make sure it is stable and reliable. If possible, use a wired connection instead of a wireless one.
• Delete the cached files in Microsoft Office Upload Center.Reference: https://answers.microsoft.com/en-us/msoffice/forum/all/how-to-fix-upload-failed-you-are-required-to-sign/c02b9e8a-1021-4da1-8c8d-0ba4a9486cb9
• Update your Office application to the latest version via File > Account > Update Options > Update Now.

Hope the information can help you. And if there have any unclear or misunderstanding, please feel free to post back and we’ll continue to help you all the time!

Your understanding and patience will be highly appreciated! Hope you have a good day and keep safe!

Answer 2

Hi @Robin Chen ,

I see your situation. Let's try something else. I suggest you try the steps below.

1. Exit all Office applications.
2. Go to Control Panel > User Accounts > Credential Manager > Windows Credentials.
3. Remove all credentials there(This will remove your stored passwords.).
4. Run regedit as an administrator to open Registry Editor.
5. From Registry Editor,

for Office 2016, browse to:HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\Identities.

6. Check to see if there are any folders listed under Identities. If yes, delete them.

You can save the files to see if the issue can be solved after performing the steps above.
