The mail has to sit somewhere before it gets delivered to you. The server that stores this mail and then sends it to your inbox is called an incoming mail server. It may also be referred to as a POP, POP3, or IMAP server. POP is short for Post Office Protocol and IMAP is short for Internet Message Access Protocol.

How do I find out what my incoming mail server is?

In Outlook, click File. Then navigate to Account Settings > Account Settings. On the Email tab, double-click on the account you want to connect to HubSpot. Below Server Information, you can find your incoming mail server (IMAP) and outgoing mail server (SMTP) names.

What should I put for incoming mail server?

Enter the mail server address and port into your mail client. Most ISPs use the standard POP3 port (110) for incoming mail. If your ISP supports Secure POP, the port number is usually 995. For ISPs that support Secure IMAP, the port is usually 993.
