Configuring Exchange Online with the New Microsoft Graph User Configuration API and PowerShell (a.k.a. Microsoft’s Latest Way to Break Your Sanity)

So Microsoft’s gone and done it again — they’ve decided that the *old* way of dealing with Exchange Online user configs via PowerShell wasn’t soul-crushing enough. Enter the shiny new Microsoft Graph User Configuration API! Because obviously, what we all needed was *another* bloody API to learn while juggling a dozen authentication methods, tokens, permissions, and other unholy rituals just to make an inbox behave.

In short, this new API lets you screw… err, “manage” user configuration data (stuff like inbox rules, settings, client configuration, you name it) directly through Graph. The article walks through how to authenticate, request permissions, and script this glorious clusterfuck using PowerShell. Spoilers: it involves registering apps in Azure, handling those evil OAuth tokens, and praying to the debugging gods every two minutes.

Basically, it’s Microsoft’s way of saying: “You thought you understood PowerShell and Exchange Management Shell? Hah! Time to dump that comfort in the trash and worship Graph instead.” The API is powerful, yes, but also a total pain in the arse to set up right. You’ll need to wrap your head around endpoints, JSON payloads, and access tokens that expire faster than your patience.

Still, once the smoke clears and your scripts finally work without throwing 401 errors, you’ll be able to automate configurations like a sadistic Exchange whisperer — pulling data, modifying user settings, and lording your newfound knowledge over the rest of your IT team like the glorious bastard you are.

So yeah, if you want to trade your sanity for fancy modern APIs and slightly better automation, knock yourself out. The detailed steps on registering your app, finding the right permissions, and slapping together your PowerShell scripts are all here in the article. Just don’t forget your aspirin, caffeine, and possibly a small sacrificial goat to please the Graph demons.

And remember, once upon a miserable night shift, I spent three hours debugging why Graph calls weren’t working — turns out I had a missing permission scope. The server laughed, I cried, and I’ve been bitter ever since.
