  How to Use GitHub Copilot with Local LLMs in VS Code

  The era of free AI is over . But you can still choose between paying for GitHub Copilot AI Credits, paying for API consumption in Azure AI Foundry, or running local LLMs (large language models) on your own hardware. This article explains the alternatives to just writing a blank check to Microsoft. Background If you're using a personal subscription to Codex (ChatGPT) or Claude (Anthropic), you probably don't need to worry about this stuff.

  How Windows makes returning to work after a vacation a thrilling experience

  Alright, I'm back to work, and the first days have been a bit of a whirlwind (as usual). And the excitement started when opening my trusty Dell XPS laptop. I figured this is a great opportunity to log some real-life experience dealing with my ultra-high-spec Windows laptops, just to add the useful angle of reflecting on my daily work experience on top of the excitement of returning to work after a vacation.

  Summer is here - I'm taking a break, and you should too!

  The summer is finally here, and I'm on vacation. The blog will be quiet for the next 3 weeks or so, as I'm trying to survive the hail, thunder and mosquitoes of the Finnish summer. Out-of-office Alright, so the Finnish summer is nothing to sneeze at, although looking at the weather forecast, I'm not sure which 1-2 days we are calling "summer" this year. Not this week, but maybe 11-12 of July, then?

  How to update an event in a M365 Group Calendar?

  Maybe nobody else needs a note to remember how to update an event in a M365 Group Calendar, but I do. And since I do, I figure it's worth documenting it here. Otherwise I'll be confused about it again in a few months (because that's how often I have to do it - once per a few months!) Background At Omnia, we've got a set-up where we have a bunch of M365 Groups, and each of these groups has a calendar.

  Copilot Cowork failing to update output documents? Easy fix!

  This week, I've had to go back to the basics - but with a twist. I ran into an issue with Copilot Cowork where it was failing to update output documents. And the fix was TRULY a classic one! Anyway - read on to have a laugh. Or maybe weep with me. And POSSIBLY pick up another solution for a problem you might encounter with Copilot Cowork in the future. Problem When Cowork tries to save the document, it fails to synchronize with OneDrive.

  Home Automation - an air quality comparison

  And now for something completely different! I had a disagreement with my wife a while ago. See, I've long suspected that our old house - originally built in the 1950s - has an air quality problem. Just a minor one, but still a problem. I say minor because, according to my measurements, pretty much the only issue is that in two rooms, the HVAC system isn't able to circulate air almost at all (which isn't surprising considering there are neither air inlets nor outlets in those rooms!

  See you at CollabDays Madrid on 4.6.2026!

  If you're anywhere near Madrid on June 4th and enjoy Microsoft 365, Copilot, developer tooling, or just a good tech event with smart people in the room, this is your cue: come join us at CollabDays Madrid 2026 . This week I'm traveling to Spain to speak at CollabDays Madrid, and I'm quite excited - it will be my first time speaking at an event in Spain, and my first time visiting Madrid.

  Are we learning anything from the recent GitHub hack?

  A week ago, GitHub announced they've been hacked. A hacker group called TeamPCP had extracted roughly 4000 private repositories and who-knows-how-much more data from GitHub's internal systems. This sounds like a pretty big deal (and it is!), but I fear we're not taking the right lessons from it. GitHub accidentally open-sourcing their internal systems? Sure, that'll lead to future breaches. But the attack vector?

  The "Canva Button" kerfuffle is everything wrong with software in 2026

  So this week, I'm writing about something completely different. And not something nice. No, this week, I'm writing about licensing. I hate licensing. But I also hate search engines and AI assistants not being able to come up with clear answers about simple questions - and that is exactly what happens when you search for "Canva Button" today.

  M365 Agents Toolkit Azure provisioning failures

  In this article, I'll share the least fun error I've recently had to deal with while building / deploying bots - I mean, agents - with Bot Framework, I mean, Microsoft 365 Agents SDK on macOS. And of course how to get around the issues. Because if I didn't find a workaround, I wouldn't be sharing this, would I? No, I would be crying about it on a GitHub issue or LinkedIn or something. Both of which I kind of did, but I also found a workaround, so here we are.

  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!
