I feel the opposite. I'm on Teams all day at work and have reluctantly opened Telegram recently to try a Claw despite having an account for years.
I've been surprised how little support there has been for Teams in the whole AI ecosystem. It seems all developers assume that the whole world is at startups working on Slack when most businesses are on Microsoft 365.
Compared to operating on text files (which is relatively very simple and something Claude Code is great for), I have a feeling it's kind of a disaster dealing with Microsoft integrations and the different file formats
Just the fact how much Microsoft lies when you click the "keep me logged in" button should tell you why nobody bothers with Teams integration with anything.
Looking forward to seeing AI ranting about pesky bullets in Word.
The main reason is just how hard it is to actually create anything that integrates with Teams. You have to jump through so meany hoops, wade through so many deprecated APIs, guess through so many half-way-wrong-by-now documentation pages.
After building a proof of concept, we decided that we will only continue Teams integration if anyone is going to pay serious money for it.
