SharePoint links without access (401 / 403)

If a link points to a SharePoint address and the server answers with code 401 or 403, the signed-in user simply has no access to that site (for example a site that is not in the SharePoint Selection form, or a site in another tenant). The link is then reported as

  • Link not verified (code: 401, access denied)
  • Link not verified (code: 403, access denied)

and it is not counted as a broken link. An address is treated as SharePoint when it is on *.sharepoint.com, on the same server as a site in the SharePoint Selection form, or when the server identifies itself as SharePoint. For other web sites, 401 and 403 are still reported as Broken link.

Results that are not counted as broken links

  • Link is OK / Link OK (code: 200, OK) - the link works.
  • ... - no check! (FTP, mail, SIP, JavaScript links, links without an address) and No check - the link was not checked.
  • Link not verified (...) - the link could not be checked (no access, or the SharePoint check could not be finished - the reason is shown in brackets).

All other results (Broken link ..., Link probably points to other SharePoint site/tenant or does not exist or is internal link, Problem to check link quality!) are counted as broken links, in the number per document and in the total of the result summary.
