Nodemailer with Office 365

I'm trying to get the nodemailer set up with outlook in office365, however when doing so I'm getting a

connect ECONNREFUSED 146.112.193.27:587

connect ECONNREFUSED 146.112.193.27:587

error message. I think this is due to not being able to set the Encryption method. Here are the connection settings required:

Server name: smtp.office365.com
Port: 587
Encryption method: STARTTLS

Server name: smtp.office365.com
Port: 587
Encryption method: STARTTLS
