03 Dec: Syncing Global Address List (GAL) to personal contacts and between Office 365 tenants with PowerShell

Hey there! Today, I wanted to introduce you to one of the small but excellent module I’ve created called the O365Synchronizer. This module focuses on synchronizing contacts and users. If you’ve ever been tasked with synchronizing Global Address Lists (GAL) across different Office 365 tenants or just wanted to sync GAL with user mailboxes so they can access contacts directly on their phones, this tool is for you.
Optimize Your Active Directory Health

08 Oct: Active Directory Health Check using Microsoft Entra Connect Health Service

Active Directory (AD) is crucial in managing identities and resources within an organization. Ensuring its health is pivotal for the seamless operation of various services. Today, I decided to look at Microsoft Entra Connect Health (Azure AD Connect Health) service, which allows monitoring Azure AD Connect, ADFS, and Active Directory. This means that under a single umbrella, you can have an overview of three services health. But is it worth it?

Removing Comments from PowerShell files/scripts

20 Aug: How to Efficiently Remove Comments from Your PowerShell Script

As part of my daily development, I create lots of code that I subsequently comment on and leave to ensure I understand what I tried, what worked, and what didn’t. This is my usual method of solving a problem. Sure, I could commit it to git and then look it up, and I do that, but that doesn’t change my behavior where I happen to have lots of “junk” inside of my functions that stay commented out. While this works for me, and I’ve accepted this as part of my process, I don’t believe this should be part of the production code on PowerShellGallery or when the code is deployed.
Function cannot be created because function capacity 4096 has been exceeded for this scope

01 Aug: Function cannot be created because function capacity 4096 has been exceeded for this scope

I had a long day today when my long-running script (10 hours) gave me weird errors with Microsoft Graph for Teams. Finally, I solved my mistakes and reran the hand to see if the report would be complete this time. Surprisingly, it gave me an error I’d never seen before. “Function cannot be created because function capacity 4096 has been exceeded for this scope”. The error is at least weird because it’s shown on a production server where I’ve just a handful of PowerShell modules installed, and I’ve never seen it on my development machine where I’ve over 200 modules.
Microsoft Graph API Connect-MGGraph Error

20 Jul: Connect-MgGraph: Keyset does not exist

I had this little issue today when I tried to schedule the Microsoft Graph script to run as a service account on a certificate. To my surprise, even tho I had all permissions required, I was getting this error message: Connect-MgGraph: Keyset does not exist. Something that didn’t show up for my user.
Password Quality Scan

28 May: Strengthening Password Security in Active Directory: A PowerShell-Powered Approach

PasswordSolution uses the DSInternals PowerShell module to gather Active Directory hashes and then combines that data into a prettified report. If you have ever used DSInternals, you know that while very powerful, it comes with raw data that is hard to process and requires some skills to get it into a state that can be shown to management or security.
Unifi Stock

16 Apr: Track Ubiquiti Unifi Stock, and get notified of changes

I am a pretty big fan of Ubiquiti and their Unifi products line. Whether it’s network equipment or their camera systems, Unifi Protect, I have it all, and I’m pretty happy with how it works. However, over the last two years, some of their stocks in the store were very hard to find. For example, I’ve searched for Unifi Protect G4 Doorbell Pro for over six months. I’ve tried local shops all around Europe, even in the Ubiquiti Europe store, to never found any of them.
