Eli5 active directory (What is active directory?)

Let’s talk about Active Directory like you are 5. Why? Because according to google, for whatever reason people keep searching eli5 active directory and ending up here. So we go.

Unable to sync Sharepoint library, and then you get a dreaded: “You’re already syncing a shortcut from this shared library:” error.

I had an end user getting this error today. He was “syncing” a Sharepoint folder (library?) to his computer, but somehow stopped and instead had created a shortcut to it within his onedrive and he didn’t know what the deal was.

Like this: (Note the weird oval icon on…

Deciphering mysterious Microsoft error codes with err.exe tool

We’ve all been there. There is some big problem, everyone’s mad at you and all you’ve got is some useless looking hexadecimal error code. That is where the err.exe program comes in (go ahead and go download/install it from that link I just gave you, or use chocolatey my preferred method) For example:  Let’s say you got this error in eventlog:  Automatic registration failed.

I had a user the other day ask to stop getting this message. Long story short, you don’t/can’t whitelist single email addresses from getting this (at least as far as I could find). Nor should you. The message should start going away as you get a few more emails from the person. So tell your user to sit back, relax, and not worry about it, and enjoy the fact they are less likely to be the cause of a million…
