Microsoft: Teams, no, you can't send anything!

Microsoft Copilot advised me to switch to Slack. Yes, really.
I wanted to send an image to my client. Via Teams. Just like everyone does since people started messaging each other.

No paperclip.

I thought: strange. So I asked Copilot (Microsoft's AI chat). It started talking about settings. Toggles on, toggles off. Admin centres. Half an hour of clicking like a mouse in a maze. Everything was set correctly.
Then the truth came out: your client is in a different Teams environment. And then it's not allowed.

Wait. What?

Is Teams a chat programme or not? I thought we were having a conversation. You just send each other things, right? Text, images, a mood board, a screenshot. Isn't that literally what a chat is?

Apparently not. Microsoft has decided that when you and your client are in separate Teams, you are not allowed to send images to each other. No files. Nothing. But you can record a video clip. Because that's logical.

And no, you can't enable it yourself. No checkbox. No option. No "are you sure?". Microsoft has decided for you that you don't want this.
Thank you, Microsoft. Nice that you're thinking for me. Top thanks...#crazyright

The best part: Copilot, Microsoft's assistant, built by Microsoft, then advised me to try Slack. Or WhatsApp. Or Discord. Or email.
Microsoft's assistant. Sending me away from Microsoft. And when I asked for verification from Claude, it said, yes or indeed WhatsApp (but it's ugly) haha and it was right.

I used to work with fifty women internally. Teams was fine then. Now I work alone and talk to external companies. And apparently, I'm the wrong customer, and MS says no Petertje talking OK, but sharing no no.
As in 1998.

And Copilot? It's actually right, I'm going back to Slack...or something.
Tips?
