I work for a web design and hosting company for doctors, and through that we manage their emails through the same hosting.
Client: I can’t sign in to my email, you guys changed my password for no reason.
Me: We did not. What is the password you’re using for which email?
Client: The password is ******* and the email is client@domain.
Me: Dot com or dot net?
Client: I’m trying to sign in to my email, not go to my website, are you an idiot?
After twenty minutes of me trying to convince him to add the .com to the end of his email, I finally signed in to it myself to show him it was working, and when he tried it himself he spent a solid three minutes of signing out and signing in again muttering about how that didn’t make sense. I left him with an outlook set up guide and a passive aggressively extensive guide on how to type in the correct email and password.
For the record, this guy is also a doctor.
