Compare PowerShell

PowerShell – Comparing advanced objects

Two years ago, I wrote a blog post on how you can compare two or more objects visually in PowerShell that works on Windows, Linux, or macOS. I've been using that for a while, but it had a specific flaw. Comparing more advanced objects that you often see (for example, returned by Graph API, two config files) wasn't working correctly, often throwing errors. The reason for this was that having nested hashtables arrays require more advanced logic. Today I've updated my module to use the ConvertTo-FlatObject function, which allows the Compare-MultipleObjects function to compare suitably more advanced objects hopefully. Of course, it should not throw errors anymore.

Office 365 Health Service

Office 365 Health Service using PowerShell

Two years ago, I wrote a PowerShell module called PSWinDocumentation.O365HealthService. The idea was simple – replicate Health Service data Microsoft offers in Office Portal so you can do with data whatever you want and display it however you like. I've written about it in this blog post. A few weeks back, someone reported that the module stopped working, and  I've confirmed it indeed no longer works! Initially, I thought that maybe some data format changed, as it changed multiple times, or perhaps the date format was wrong again, but no. Microsoft has deprecated Office 365 Service Communications API reference and instead tells us that Service Health is now only available via Microsoft Graph API. Is it only me who didn't get the memo about this?

Difference between GetTempFileName() and GetRandomFileName() that got my ass kicked

Today's story is about me making assumptions on how things work based on the method's name. As the blog post says, I want to focus on two similar methods – GetTempFileName() and GetRandomFileName(), when using PowerShell. Still, since those methods are .NET based, it applies to a whole range of other languages – C#, F#, VisualBasic, and all others that I've never used.

Mentioning users in notifications using PSTeams PowerShell Module

Microsoft Teams over the last few years have grown into an excellent and flexible tool for both small and big companies. Having the ability to chat with users, store files or have all sorts of data in one place makes it easy and functional. Of course, it has its fair share of issues, but it's getting better. One of the cool features of Microsoft Teams is being able to send notifications to Microsoft Teams Channels using WebHook Notifications. In the beginning, this feature was pretty limited, but after a few years, it got much better with support for Adaptive Cards, List Cards, Hero Cards, Thumbnail Cards, and Office 365 Connector Card.

Duplicate SPNs

Finding duplicate SPN with PowerShell

Duplicate SPNs aren't very common but can happen in any Active Directory as there's no built-in way that tracks and prevent duplicate SPN's. One has to either know all SPN's in the environment, track them or check each time whether it already exists or not. Things get more complicated with larger Active Directory environments as people change, new apps are added, old apps are forgotten, but SPNs prevail.

ConvertTo-HTML

Solving typo problems with Fuzzy Search in PSWriteHTML

One of the everyday use cases with PSWriteHTML is to create a simple view of PowerShell data in a table. While PowerShell comes with a built-in cmdlet ConvertTo-Html, it's basic in its functionality. It makes an HTML representation of PowerShell data, but it brings no CSS, JavaScript, or other functionality. While for some use cases, it's enough, the other times, you need to make an effort to make it usable.

Active Directory Domain Services could not replicate the directory partition – The replication operation encountered a database error

If you ever encounter an error while trying to create a new domain within a forest saying, “The replication operation encountered a database error,” it makes you sweat a bit. Your brain tells you it will be a nightmare to fix, do I have proper backups to make it happen, and the question “why now” shows up.

Office 365 Org Settings

Configuring Office 365 settings using PowerShell – The non-supported way

Office 365 is a huge beast. It has so many services that it's hard to track all of them. It's even harder if you want to manage Office 365 using PowerShell. Microsoft makes many different PowerShell modules available for you, such as AzureAD, AzureADPreview, ExchangeOnline, MicrosoftTeams, and recently, Microsoft.Graph. But even with so many different modules, there are still tasks that Microsoft won't let you do from PowerShell. But it doesn't mean that it's not possible to do it. I've spent some time tracking how Microsoft does things while you click thru the interface and created an O365Essentials PowerShell module that can do it in an automated way.
