SharePoint Trigger Unauthorized Error

Posted on by Community Power Pla...

Hello,

I am currently having an issue with a flow I have that triggers from a SharePoint site. The flow was working fine previously and had many successful runs, but all of a sudden the connection to the SharePoint site is now unauthorized. It seems like the issue was addressed back in May in this post: Microsoft Flow - SharePoint Connection - Unauthorized? The issue was said to be resolved a few days after the post was made and similar issues were reported. However, this seems to be happening once again!

Does anyone know how I should go about resolving this? Any help is greatly appreciated.

Have you verified that permissions haven't changed on the Site/list that the Flow Trigger is connected? That's the first thing to check.

Thanks for the prompt response. The permissions for the SharePoint site have not changed. I was previously an owner, and I am still an owner of the site. Would deleting and re-creating the connection be my next step?

I might try a quick test Flow with a new connector before I delete the existing connector, but that's probably the next step yes.

Hi @Anonymous ,

MS Flow Support does not currently display any messages about SharePoint services that are not working properly.

I have been testing with SharePoint connector-related features today, and everything is fine.

Please try clearing the browser cache and re-creating the connection for testing.

Best Regards,
