I've got an external user who has had access to a SharePoint 2016 site before. He couldn't get in today and keeps getting the 'Access required' no matter how many times i send him a Sharing Request add him to the groups or Approve his requests he keeps coming back to the "Access Required" page. Any ideas?


You could go to user inormation list, delete the external user there. Then add the user in the groups again.

The url of user information list: https://yoursites/_layouts/15/people.aspx?MembershipGroupId=0

  • Ahhhh, he's not in that list so that could be the issue? – darrenfloyd666 Sep 13 '19 at 10:03
  • So if a user wasn't in that group they would be able to gain access or would continue to get the Access request page? – darrenfloyd666 Sep 14 '19 at 11:00
  • If a user isn't in the user information list, he do not have access to the site. When you grant a user permssions, the user would be added to the user information list automatically. – Michael Han_MSFT Sep 16 '19 at 1:03
  • Thanks Michael. What could be causing the list not to be updated and is there a way I could manually add users? – darrenfloyd666 Sep 16 '19 at 8:48
  • You could go to site settings-> site permissions, give this user permissions manually. – Michael Han_MSFT Sep 16 '19 at 8:56
