When configuring your e-mail application such as Outlook, use these ports.
Notes:
POP3 is a standard mail protocol used to receive emails from a remote server to a local email client. POP3 allows you to download email messages on your local computer and read them even when you are offline. Note, that when you use POP3 to connect to your email account, messages are downloaded locally and removed from the servers. This means that if you access your account from multiple locations, that may not be the best option for you.
IMAP is a mail protocol used for accessing email on a remote web server from a local client. IMAP and POP3 are the two most commonly used Internet mail protocols for retrieving emails. Both protocols are supported by all modern email clients and web servers. Use IMAP if you want to check email from multiple computers or devices. Use POP3 if you want your email always accessible, even when there's no Internet connection. But, be aware that email will only be available on the device to which you downloaded them.
SMTP is the standard protocol for sending emails across the Internet.
