SharePoint 2019 + Anonymous Access + Microsoft Edge = CSP issues

Occasional Contributor

I do not know if this also occurs for SharePoint Online, if someone can test this for me, I would appreciate it.


When accessing my SharePoint 2019 site on Microsoft Edge as an anonymous user, I get paraded by a bunch of login dialogs asking for credentials. Every time a cancel is hit, it continues trying to load the page until the page is more or less finished loading. See below screenshot for a snippet of the logs appearing in DevTools.




The anonymous users have the following permissions:

  • View Items
  • View Pages
  • View Versions
  • View Application Pages
  • Use Client Integration Features
  • Open

This works on all other browsers (including ironically Internet Explorer).


Does anyone know how to resolve this issue? Is there a web.config, or permission setting that I am missing?
