Common issues syncing Microsoft SharePoint lists offline

This document contains troubleshooting steps for common issues with syncing lists offline.


Sync icon doesn't appear
  1. Open the Windows task manager and look for “Microsoft SharePoint (Microsoft.SharePoint.exe)” under Processes > Background Processes.

    Microsoft SharePoint shows as a background process.

    • If SharePoint is running, continue to step 2.
    • If SharePoint isn't running, List sync isn't running. Your orgnization might have prevented it from synching, see Lists sync policies.
  2. Enable Web App Logging.

  3. Check the console log for a line that includes "Found list". It will look similar to this example:

    Console log line that starts with Found List

    • If there is no log line starting with “Found list”, it might mean the List sync process hasn't synced the list yet. Wait for silent configuration or syncing to occur.
    • If the line with "Found list" shows “unsynced:true", the list is currently unsynced because List sync doesn’t support it. This is by design, and List sync will be extending our support for lists in future versions. See the "Current Limitations of List sync" section in Edit lists offline.
  4. If Microsoft.SharePoint.exe is running, and there is a “Found list” log line that does not show "unsynced", it could be a client issue. See Contacting Support.

Sync icon stays on for more than 10 minutes

The sync icon will often be on for a few minutes, appearing next to the list name:

The sync icon appears next to the list name.

If the icon stays on for more than 10 minutes, first make sure that the client device is online. If it is offline, the sync icon will stay on. If the client device is online, and the sync icon shows for more than 10 minutes, see Contacting Support.

Local changes not synced
  1. See if there are any conflicts or failed uploads. Navigate to View > All items > Items that need attention.

    Conflicts are shown in the menu.

  2. If there are conflicts, refresh the page and try the update again.

  3. If there are no conflicts, or the conflicts continue to appear after step 2, see Contacting Support.

Information needed to open a Microsoft support request
  • Required The email address used to log into the List web app.
  • Required A general time stamp of when the issue occurred (within a few hours is usually enough).
  • Required A description of the issue.
  • Required Browser type (Edge, Chrome, etc).
  • Optional Screenshots of the issue. The more detail in the request, the more likely Microsoft team will be able to quickly assist and won’t need to ask for more information.
  • Optional If you enabled web app logging during debugging, send a copy of the console logs. You can right-click the console in the browser tools and select “Save as” to generate a file.
  • Optional The ticket might require client logs to be collected separately. See “Collect Microsoft SharePoint client logs” below.

Enable web app logging
  1. Open the browser and navigate to the list in question.

  6. Add sharepoint.datasync.nucleus.logToConsole in the right pane by selecting an empty line. Set the value to true.

    sharepoint.datasync.List sync.logToConsole is added with the value set to True.

  7. With the browser tools still open, switch to the Console tab and press F5 to refresh the page.
