No_Oauth_Token: Access token was not returned

Question

Unable to access sharepoint via Files Connect.

1. A user with System Admin Permission created.
2. Enable Files COnnect in my org.
3. Created a permission set to access Files Connect Online and assigned to the above user.
4. Got Consumer Key and Consumer secret, and with them I created Auth Provider in Salesforce.
5. Set Authorize end point url and token end point url.
6. Created External Data Sources

I got my External Data Sources - Authenticated as well.

But when I try to "Validate & Sync" it says "OAuth token expired".

Please advise.

Answer 1

See steps 6-8 in the steps to setup Files Connect

You still need to:

• Define an External Data Source for SharePoint
• Check External Data Source Access on the Permission Set
• Edit the Permission set and add specific data sources to the Enabled External Data Sources list

Answer 2

While setting XML Permission in Sharepoint at appregnew.aspx

Change the Permission XML from "http://sharepoint/content/sitecollection/web" to "http://sharepoint/content/sitecollection"

This change had worked for me.
