In some cases when a user with full control clicks the Pending Requests page (/Access%20Requests/pendingreq.aspx) Image 1 below – s/he may receive an error “Sorry, this site hasn't been shared with you” (Image 2).

There are couple of options (see the end for reference) how to resolve this issue – this article walks you through using SharePoint Designer to resolve this issue. I personally find this option easier :-).

Here are the steps to resolve the issue:

  1. Open the site in SharePoint Designer > All Files > Access Requests List (Image 3)

2. Right click the Access Requests > Properties (Image 4)

3. Click Permissions for this list (Image 5)

-          - List permissions page opens in the browser

      -        Add the necessary permission - SharePoint group which has full control to this site.

        Have the owner test out now. This should resolve the access denied error. Hope this help!

        Here is another approach to resolve this issue – even though this Microsoft KB talks about SharePoint Online; I was able to resolve on-premise issues following the approach.

       "Access Denied" to Access Requests list or “Request approval failed” when you process a pending request in SharePoint Online
