We have 3 Global Admins and 2 of the 3 have this problem and the other does not.

When going into Sharepoint online and trying to change the Sharing permissions for the group, we get the following error:

URL: https://sitename-admin.sharepoint.com/_layouts/15/online/AdminHome.aspx#/sharing

Error on loading page: UntaggedErrorWithStatusCode403: No inner error provided

Error when attempting to change permissions with the slider: UntaggedErrorWithStatusCode403: No inner error provided Access denied. You do not have permission to perform this action or access this resource.

I can't see any other issues like in my google searches.

Any ideas?

  • Do all 3 have SharePoint license assigned? – Jussi Palo Jul 26 '19 at 8:27
  • Yep, I have SharePoint licensed for my user. Chris. – Chris Clayton Jul 27 '19 at 9:30

You can compare the difference between the three global admins.

To change external sharing settings, you need to be a global or SharePoint admin and have SharePoint license. In my test, if a global admin doesn't have SharePoint license, he will be unable to access SharePoint admin center.

  • I can access SharePoint admin centre fine. – Chris Clayton Jul 27 '19 at 9:31
  • I have 3 Global Admins, all 3 have sharepoint licenses, all 3 can access Sharepoint admin pages, only 1 can access and change global sharing within Sharepoint online. – Chris Clayton Jul 28 '19 at 21:04
  • When testing the 3 accounts, did you use a same machines or different machines? Please try to clear your browser cache and test again. If this issue still exits, you can try to change the 2 problematic global admins roles to others and revert it again, then test again. – Kally_MSFT Jul 30 '19 at 8:23
  • I needed to download the Sharepoint Online Management Shell (microsoft.com/en-us/download/details.aspx?id=35588) Connect using: connect-sposervice Enter my site URL mysite-admin.sharepoint.com Run: Set-SPOUser -Site mysite-admin.sharepoint.com -LoginName myuser@mydomain.com -IsSiteCollectionAdmin $true This resolved it. – Chris Clayton Jul 31 '19 at 20:26
