Sending Messages to Microsoft Teams from PowerShell just got easier and better

Christmas time is upon us, and I’ve decided that my PSTeams module needs some love. I wrote it in late 2018 and updated it a few times at the beginning of 2019. This release hopefully is worth of having 1.0 version number. I don’t do that often and usually go for build numbers changes only, but Microsoft Teams message cards have their limits on functionality. Therefore, there are not many things that can be added unless Microsoft opens up and gives us all the cool features of Adaptive Cards. PSTeams module uses Webconnector to send messages to Teams. That method only supports Message Cards, which even Microsoft calls Legacy. But legacy doesn’t mean fully functional with some cool features of their own. If you’re new to PSTeams you may want to read those 2 posts below to get information how to set it up.

Getting Azure Health by parsing HTML using PSParseHTML

Some time ago I’ve wrote PowerShell way to get all information about Office 365 Service Health, and if you were thinking that I would try the same concept for Azure Services you were right. However, I failed. This is because Office 365 Health can be gathered using Microsoft Graph API, and Azure Health information, as far as I know, is not available in the form I wanted it. Azure Status is available as part of Azure Status website. Contrary to Office 365 health you don’t have to login to your Office 365 tenant to read it.

What do we say to health checking Active Directory?

Setting up a new Active Directory is an easy task. You download and install Windows Server, install required roles and in 4 hours or less have a basic Active Directory setup. In an ideal world that would be all and your only task would be to manage users, computers, and groups occasionally creating some Group Policies. Unfortunately, things with Active Directory aren’t as easy as I’ve pictured it. Active Directory is a whole ecosystem and works well ranging from small companies with ten users to 500k users or more (haven’t seen one myself – but so they say!). When you scale Active Directory adding more servers, more domains things tend to get complicated, and while things on top may look like they work correctly, in practice, they may not. That’s why, as an Administrator, you need to manage Active Directory in terms of its Health and Security. Seems easy right? Not quite. While you may think you have done everything, checked everything, there’s always something missing. Unless you have instructions for everything and can guarantee that things stay the same way as you left them forever, it’s a bit more complicated. That’s why Microsoft delivers you tools to the troubleshoot your Active Directory, such as dcdiag, repadmin and some others. They also sell monitoring solutions such as Microsoft SCOM which can help and detect when some things happen in your AD while you were gone. Surely there are some 3rd party companies give you some tools that can help with a lot of that as well. Finally, there is lo of folks within the community creating PowerShell scripts or functions that help with some Health Checks of your Active Directory.

Comparing two or more objects visually in PowerShell (cross-platform)

For the last few weeks I’m working on a small project, that should be released within next few weeks (it is open source so don’t worry – you’ll get to play with it). This project requires me to compare two or more objects and tell if those are equal and if those aren’t to what degree. Of course, PowerShell offers built-in functionality via Compare-Object command. It’s mighty but it leaves comparing differences, different properties to you. While there are probably other solutions that help users compare objects, I haven’t found anything that would meet my requirements. After I’ve written Compare-MultipleObjects function, I thought it could be interesting to implement visual comparison – you know human-readable – and I had the perfect place to apply it.

Formatting and minifying resources (HTML, CSS, JavaScript) with PowerShell

When you work with HTML, CSS, and JavaScript, you often meet three versions on how those are stored in files – minified, formatted, somewhere in the middle (usually a total mess). I have all three versions in my PSWriteHTML module. Some are minified 3rd party resources, some are generated by my PowerShell commands (and are a total mess when it comes to formatting), and finally, some are formatted resources by using built-in VSCode features. In whatever form they are, they generally have no impact on how browsers display them. Browsers will read them in any kind and not care for how they look.

Working with HTML in PowerShell just got better

Last few weeks, I’ve been working on making creating HTML based Dashboards, Reports, and Emails better. PSWriteHTML already allows fancy looking reports or emails without much effort, but this release makes it even more helpful. I will be mixing three PowerShell modules in this blost post – PSWriteHTML (responsible for creating HTML/CSS/JS code), Emailimo (simplifies creating emails based on PSWriteHTML) and Dashimo (simple dashboard building). If you’ve never heard of those modules before I encourage you to start from earlier blogs about them to understand the concepts before you dive into this one. Hopefully, those will give you some ideas that will match what you will learn today.

Sending HTML emails with PowerShell and zero HTML knowledge required

I saw this article by Altaro tweeted Building PowerShell Tools for MSPs: HTML Tables for Reporting, and it describes how you can create HTML emails with just a few lines of code. Luke created that article in 2018 (tweets from the archive I guess), but I just saw it now so thought I would make a slight comparison. In 2018 I would probably go the same way as shown by Luke Orellana, who takes a simple example of querying WMI to get disk drive sizes and send them over, formatted via Email.

All your HTML Tables are belong to us

Last few days, I’ve fulfilled my little dream related to building HTML tables. You know I’ve been using HTML based scripts for a long while for Microsoft Exchange from multiple people like Steve Goodman or Paul Cunningham (and others) and when I was going thru their PowerShell building code on how they create an HTML table with multi-row titles I thought Those guys are crazy. The effort to build an HTML table for a report for a person who has no clue how to do it is not something one can easily digest and understand. Sure I’ve learned how to build HTML tables at some point, but there was one final piece that I was missing – multi-row headers. If you don’t know what I mean, and how they look like the below image from Steve’s Goodman script should give you a hint.

Meet Emailimo – New way to send pretty emails with PowerShell

When reading this blog post, you may be thinking that there’s nothing new one can add to emailing with PowerShell as there were tons of articles in recent years covering this subject pretty good. It’s all known, and people have used it since the early days of PowerShell. You can even send an email with just one line using Send-MailMessage. Now, this post is not about that. This post is about sending HTML based emails. You see when you want to send an email that is just text based that’s pretty trivial. Things get complicated when you want your emails to have some colors, some tables, some links or some lists. This is where you have to involve HTML and CSS. Since I’ve been working with PowerShell for a while now, I’ve seen my share of scripts/modules or blog posts that cover this but one thing that usually hit me – it was sometimes tough to understand what is happening, what the author is doing, and what happens if I change this or that. While I’ve seen people dismissing programmers doing HTML / CSS or JavaScript for not being real programmers, I disagree entirely. You have to know what you’re doing if you want your stuff to look good. I’ve spent days or even weeks playing with HTML/CSS/JS, and I must admit half of what I do I don’t even understand until I see the output. So before you go and tell people that HTML/CSS is easy, think again.

Out-HtmlView – HTML alternative to Out-GridView

One of the most comfortable output’s in PowerShell to work and analyze data is Out-GridView. It’s handy as you can search, sort and have things done quicker than trying to do things in the console. However it’s currently not available in PowerShell Core (PowerShell 6+), and when it is available in PowerShell 7, it will NOT be cross-platform. Since I had released Dashimo a few days ago, I thought it was trivial to make a simple command out of it that could solve this problem.
