I fixed a client’s Outlook many years ago with telnet. The app just wouldn’t download email. No error.

So, with the guy looking over my shoulder, I telnet to the email server, list his messages, and discover that there’s an email with an attachment that’s too big for Outlook to handle. Read some basic info from the message so he could confirm that deleting the message was fine - deleted the message, and Outlook worked again.

Dude was thrilled. Fun times.
