Claude can only connect to one Microsoft mailbox. That's the wall most people hit, and most of them stop there.
We built a way around it. A second connection that runs on my own laptop, so Claude works in my work email and my personal Hotmail, and always knows which one I mean.
My personal inbox had 2,248 emails in it. One afternoon of talking to Claude later, it had 9. 57 folders became 4, and 23 mailing lists are gone.
It can't send, forward or permanently delete, and it shows me a preview before it moves anything. Those are my rules. Your setup, your rules.
It did make mistakes. I caught them, and everything came straight back. That's why we keep a human in the loop.
If Claude can only see one of your inboxes, send us a message about your email setup. x
