Antti K. Koskela - Microsoft MVP, M365 and Azure Solutions Architect, and the person behind Koskila.net
Welcome to Koskila.net. I am a Finnish software developer entrepreneur living in the countryside, and this is my personal professional blog for documenting solutions that are genuinely useful in real work.
The focus is Microsoft technology, cloud architecture, and enterprise software development, but the spirit is broader than any single stack.
The blog has been online since 2009 and in its current shape since 2015. Over the years, it has grown into a long-running notebook of lessons from consulting projects, architecture work, product implementation, and practical troubleshooting that teams can apply quickly.
Latest posts from the workshop
Start here for the freshest articles. Every post is written to be practical, specific, and immediately useful for teams building and operating real software.

Today: See you at aMP Rennes 2026!
I'll be talking about Microsoft Foundry, different kinds of agents, Copilot Studio and of course M365 Copilot with my good friend Michaël Maillot at aMP Rennes 2026 - today! We have a demo, another demo, some tales from the trenches and zero fluffy marketing speak to share. There will be both live coding and a Copilot Studio agent, and a lot of chances for things to go terribly wrong. Again. Background I feel almost endlessly lucky for being able to participate in and speak at different events around the world.

Where did Copilot disappear in my PowerPoint on Mac?
This article explains how I discovered where the Copilot button went in PowerPoint on my Mac. Sounds dumb (and it is), but hey - I've ran into it twice, I've had to google it twice, so the next time it happens, I wanted to have a record of where to look. Let's get to it. Background So, I opened PowerPoint today. And like probably nobody else in the room, I wanted to access Copilot. But there was no Copilot. Nowhere I could see, anyway.

Thanks for attending our session at AI Maitri Global Summit 2026!
This year, I decided to try and participate more actively in different events and widen my repertoire - meaning, I wanted to try and see if there are online conferences, in addition to in-person events, that would be rewarding and useful to submit my sessions to. On a whim, we decided to submit to AI Maitri Global Summit 2026, since we had a great use case to present for the event's Manufacturing track. And boy am I happy we did! Something usual... And something unusual!

How to install the VS Code wiqd extension?
After getting back to consulting, I've been in the lucky/unlucky situation where I get to create and maintain different agent setups for various clients, each with their own unique requirements and challenges. That means I get to build agents with M365 Agents Toolkit, Foundry and even (ewww) Copilot Studio. One of the recurring challenges I've faced is dealing with the quirks and unexpected behaviors of various development tools, particularly when trying to install extensions in VS Code that seem determined to resist my efforts.

How to modify the M365 Copilot Brand Kit?
This article explains how to modify the Microsoft 365 Copilot Brand Kit. Because apparently, YES, you DO in fact need an article explaining how to do it! Especially so since Microsoft is retiring public contributions to their documentation, because AI can update the docs so much faster than a collective of half a billion human contributors. Does anyone else swear at their little AI helpers? I've found myself getting quite irate with every single one of them - perhaps the only one that I rarely swear at is, surprisingly, Siri...

The person behind the posts
I started freelancing as a web developer at 14, and the fascination never stopped. Today I work as a Lead Technical Consultant, helping customers tackle complex Microsoft 365 challenges.
This site exists to document what works, what fails, and what can be improved in Microsoft-focused engineering work. It is intentionally broad because real-world software problems do not arrive in neat categories.
If you value direct examples, tested fixes, and practical patterns over polished theory, this is the right place to browse.
Elsewhere on the web
This is the main home for Microsoft-focused writing, while ThoughtsOnTech.net covers gadgets and consumer-tech observations. The split keeps each stream focused and easy to follow.
