  GitHub Copilot's Freemium Era Is Over

  A week ago I wrote about how the all-you-can-eat AI buffet is seemingly coming to an end, and how practically every major AI vendor has been tightening the screws. I noted that Microsoft looked like a relative outlier — still following the all-inclusive (for M365 Copilot) or generous grants (GitHub Copilot's "Premium Requests") models, while competitors were moving to token metering. Well, that didn't last long.

  How to install Copilot Studio Agents in Teams (even when it fails)?

  In this week's article I'm sharing some of my experience with installing Copilot Studio Agents in Microsoft Teams. Namely, how to install them even when Teams says "no". Background So you have built a beautiful Copilot Studio Agent, and now you want to use it in Microsoft Teams. How do you get it there? Well, you of course navigate to "Channels" and select "Teams and Microsoft 365 Copilot" as the channel type.

  No, New Outlook (NEW) still can't subscribe to an online calendar

  This article explores the problematic task of adding an online calendar to New Outlook (NEW), and how to work around the issue by using Outlook on the web (OWA) instead. Background Now, unlike in Windows (at least in theory), on a Mac you can't change the default calendar app to something else than Apple Calendar. So if you click on a calendar link in an email, it will open in Apple Calendar - and if you want to subscribe to an online calendar, you better subscribe to it in Apple Calendar.

  USA - giving strong 'Not This Year' vibes 🥲

  What exactly is happening in the USA? The once-great country seems hell-bent on shooting themselves in the foot again, again and again, and knowing what a bad shot most people are, I've chosen to stay out of the line of fire this time around and canceled my travel plans. It bleeds my heart not to make it to the MVP Summit in person to meet up with all the amazing people, and of course to take the excuse to go on a little road trip to check some of the missing states off the map.

  Happy 25th birthday, SharePoint! 🎉

  This article is my love letter to the 25-year-old workhorse in the Microsoft ecosystem - SharePoint. Let me take you on a wild ride through my personal journey and love-hate relationship with SharePoint! Intro So on March 2nd, 2026, SharePoint turned 25 years old. It can now not only drive, but also vote and drink - hopefully not at the same time, even if drinking and voting DOES sound like a great time! My first day job in 2011 was a SharePoint developer.

  Thank you Cloud Tech Tallinn 2026!

  Ever had one of those conferences that are fun, informative, and did I say - fun? No matter whether you're a speaker or an attendee, Cloud Tech Tallinn 2026 was one of those! For me personally, what started as "hey, we should geek out on this new AI stuff" with Michael Maillot over half a year ago, turned into 45 minutes of pure Microsoft 365 Agents SDK goodness - and chaos! - complete with a demo that actually worked (yes, really!

  What do you do when AKS randomly changes IP address?

  A working service can stop answering overnight when the IP beneath your AKS ingress changes — and when DNS records or firewall rules depend on that address, the fallout can be immediate and painful! This article explains why AKS sometimes changes public IPs, how to tell whether your cluster uses a single address or separate inbound/outbound addresses, and practical steps to prevent surprises or recover quickly when the IP does change.

  Copilot, Blazor, and a Mac Mini in a Pear Tree — koskila.net in 2025

  It’s that end‑of‑year ritual again — a short pause to look back at what actually happened, what broke, and what was surprisingly useful. This year mixed wins with plenty of frustration: Frustration with unreliable hardware and Windows, cold start with macOS, the challenge of balancing family, work, and personal projects with speaking at conferences again; and of course the ongoing learning path with agentic software development.
