SharePoint connection failed: UnauthorizedAccessException

Posted on by Jack13

Hi,

I have build a flow which generates an excel export using excel online in Sharepoint folder. The flow has worked fine up to now but since this morning I am getting the following error:

{

"917656; Access+denied.+Before+opening+files+in+this+location%2c+you+must+first+browse+to+the+web+site+and+select+the+option+to+login+automatically.",

}

How and where can I enable automatic login for the sharepoint folder for all users of the power app.

Hi @Jack13 , Account used in the "Get file content" action connection should have access to the SharePoint library. Make sure the file that you're trying to access do not have unique permission, otherwise it should work without any error

Hi @Jack13

Problem seems like it was permissions related in the sharepoint datasources. One of my flow I upgraded the permissions and the flow automatically reran itself.

Hi @JojiCherian

You may directly use "SharePoint" cloud connector in PAD as those are available in latest version.

Here is the list of cloud connector supported in PAD:

Hi @ManishSolanki ,
Thank you for your prompt response .Before attempting the PAD Web Service , I tested it with cloud SharePoint connectors , that went well.
However , the current requirement is to exclusively use the PAD Web Service.
