Microsoft Defender for Office 365 Licenses for Shared Mbx
Shared mailboxes might need Microsoft Defender for Office 365 licenses, but how do you identify how many licenses? We use PowerShell to do the job.

Just a friendly reminder as we go into the holidays:
Folks don't have to explain to you why they don't drink.
If you offer them a drink and they decline, don't ask them why. It's not your business.
Just offer them something without alcohol to drink instead. And move on.

It's on apt. It's literally on Cargo. It's on DockerHub with ads. It's literally on nuget. You can probably find it on snap. Dude it's on portage. It's a Homebrew original. It's on pacman. You can download it on nixpkgs. You can go to pkgsrc and watch it. Log onto the Windows Store right now.

Well, it happened for the first time in my career. I've found an #ActiveDirectory user object that is too large to sync to #EntraID. Interesting. Many, many thousands of users I've had in my tenants and am just now coming across this.

Nah, that's completely reasonable. There are plenty of well-known orgs with process and systems issues that allow stuff like that to happen. With all the complexity of technology and such, people and process are somehow always the most difficult part to get completely right.

I don't like a lot of the decisions Microsoft makes about stuff with their products how stuff works, etc.
But I tell ya what. Everything MS makes is bliss compared to having to administer a Google Workspace tenant. This garbage shouldn't cost money.

#Intune finally supports native PowerShell scripts for Win32 app installs. No more wrapping scripts inside .intunewin files. You can update scripts without repackaging and choose 32 or 64 bit. Way cleaner and easier to manage.
PowerShell Script Support Added for Win32 Intune App Deployment
PowerShell script support has been added directly to the Intune app deployment Wizard. Learn why this is a great improvement.
