Setting up Outlook Email with IMAP or POP3

Table of Contents

Setting up Outlook to work with IMAP or POP3 involves several steps.

IMAP leaves the email on the server and is designed to share email among devices (desktop and phone).

POP3 downloads the email to the device and isn’t designed to be shared.

In most cases at NAS, the incoming and outgoing server is mail.domain.com and servers use SSL. For outgoing email, we use SMTP user authentication to send email.

Secure Email
IMAP Incoming SSL Port: 993
POP3 Incoming SSL Port: 995
IMAP/POP3 Outgoing SMTP Port: 25 (with SMTP Auth)

NO SSL? (May work on older servers)
IMAP Incoming Port: 143
POP3 Incoming Port: 110
IMAP/POP3 Outgoing SMTP Port: 2525 (with SMTP Auth)

Here’s a brief guide for each – note that this is generic and the port numbers for NAS are included:
