Syncing issues with Office 365

UPDATE Dec 14: Please let us know if you have seen improvement and you’re now able to open your apps.

UPDATE: Per Microsoft twitter feed: “We corrected an issue with a third-party networking provider and have validated through monitoring that service has been restored.” You can verify that this is working for you by signing in with your Microsoft account. If you continue to encounter issues, please post to this thread.

AppSheet users with data hosted in Office 365 may currently be experiencing issues syncing their application data. It appears that the source of the issues may be with the Office 365 API. O365 admin users can check the outage status in their Microsoft Portal Admin page - instructions are included below:

  1. Go to OneDrive or SharePoint and click on the menu button on the top left to open the menu
  2. Click on “Admin” in the menu to go to the admin portal (note: only admin users can do this)
  3. In the admin page, open the Service Health page to view all incidents
  4. Click on the incident for more details

We will give future updates in this thread.

Non-admin users might want to check Microsoft Status twitter feed for updates. The tweets might not be up-to-date, but Microsoft is now aware of the situation.

This issue has not yet been resolved on the Microsoft side. We will continue to post additional information in this thread.

Adding this to the thread for reference if you continue to encounter issues:

If you are experiencing syncing issues (failed syncs, but also degraded performance), we are recommending that you refrain from using the apps. There is a risk that retries will result in conflicts or duplicates in the data.

If you continue using the app, or if you have already made a number of changes since the outage started, it’s a good idea to go through the spreadsheet to check for missing or duplicate rows. You can also verify their data against the app’s audit log.

According to Microsoft the issue has been resolved.

However, I’m still unable to sync my app.

I am having these same issues. This began this morning and has not cleared up. Denver, CO.

Me, too

Microsoft has stated that they have corrected the issue on their end. We’re currently investigating the issue to provide better information as soon as we possibly can.

For those experiencing errors, is it a different error message than what you were receiving before or still the same?

Microsoft says fixed, but apps still not working?

Times out when syncing

Thank you for that information. I’ll post more information when it becomes available.

What is the error message you are getting now?


The QualityGate-622224 app did not load successfully. Please contact the app creator.

Unable to fetch app definition. Error:Error: Data table ‘QualityGate_Records’ is not accessible due to: Timed out waiting for a resource. The reason is usually a very large/slow loading table or a cross-table cycle in AppSheet formulas…/n

Same problem here

Thank you for reporting the exact messages. We are still looking into it.


It seems that the Microsoft servers are taking some time to recover after their outage. We’re monitoring the situation.
Thank you

any new, I am still down
