Troubleshooting: Anonymous access on a public SharePoint site collection failing

Ah, everyone’s favorite, classic topic! Debugging SharePoint On-Premises configuration issues is the best thing since sliced bread, right? This post is about allowing/enabling Anonymous Access to a site collection – a simple configuration, that “simply works” like once every ten times you try it.


A lot of different ways to hit your head on this one. In any case, your on-premises SharePoint doesn’t allow anonymous access to a site where you are trying to allow it. Most typically, they’ll just encounter 401 error when accessing the site, or they might be missing some of the content or styles, resulting in partially broken site.


Usually incorrect configuration or non-published resources. Multiple reasons can cause this, though, I’ll describe some of them below with the solutions.


A lot of things to check – let’s go through all of the most typical issues here! Continue reading

How to get rid of Foxit Drive in Foxit Reader

The default save location is “Foxit Drive”, and it pops up any time you try to save your document, and at least for me interrupts my workflow. This post describes how to get rid of it, and make Foxit Reader even better!

Description of the issue

Solving error “AADSTS90013: Invalid input received from the user”

I stumbled upon a customer, that complained about some pages in their intranet throwing weird errors with authentication. Those pages seemed to have one thing in common – there was a Yammer embed (or a SharePoint script webpart with Yammer embed script in it, to be precise) there.
