Access Your Account Using IMAP or POP Email Programs


Applies to: Office 365 for professionals and small businesses, Office 365 for enterprises, Microsoft Exchange, Live@edu

Topic last modified: 2012-07-31

If your email account supports POP3 and IMAP4, you can choose from several different POP3 and IMAP4 email programs to connect to your account. The features supported by each email program vary. For information about the features offered by specific POP3 and IMAP4 email programs, see the documentation that's included with each program.

If the email program you are using supports Exchange accounts (for example, Microsoft Outlook, Microsoft Entourage 2008, or Apple Mail for Mac), we recommend that you set up an Exchange connection to your account rather than a POP or IMAP connection. Exchange connections support more features than POP or IMAP connections. For more information see Supported Email Programs and Features.

If you don't know if your email account supports POP3 and IMAP4, contact the person who manages your mailbox (sometimes called an email administrator).

Instructions for POP3 and IMAP4 Programs

If the program you're using isn't listed above, use the following information to set it up to get your email:

  • User name   Enter your user name (for example, tony@contoso.com).

  • Password   Enter your password.

  • Authentication   Use the same user name and password to authenticate with the incoming or outgoing (sending) email server. Don't use "Secure Password Authentication".

  • Server names, port numbers and encryption methods   Before you set up a POP3 or IMAP4 email program, you need to look up your own POP3, IMAP4 and SMTP server settings.

    Watch this video to learn how to find your server settings for your POP or IMAP email program.


    To find your server settings, sign in to your email account using Outlook Web App. After you sign in, click Options > See All Options > Account > My Account > Settings for POP, IMAP and SMTP access. The POP3, IMAP4, and SMTP server name and other settings you may need to enter are listed on the Protocol Settings page under POP setting or IMAP setting and SMTP setting.

    If you see Not available next to POP setting, IMAP setting and SMTP setting, your account may not be set up to use POP or IMAP email programs. For more information, contact the person who manages your email account.

What else do I need to know?

  • Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are methods to help secure communications between your computer and the email server. Some email programs refer to SSL or TLS as "encryption". In most email programs, you need to open an "Advanced" setting or tab to set SSL for POP and IMAP connections and TLS for SMTP connections.

  • Your email program may automatically try to use port 110 if you're using POP or port 143 if you're using IMAP. If your email program shows port 110 or 143, be sure to select SSL encryption. Then, enter a port number of 995 to replace the default port number (110) if you're using POP or a port number of 993 to replace the default port number (143) if you're using IMAP.

  • Your email program may automatically try to use server port 25 for SMTP. If your email program shows port 25 for SMTP, be sure to select TLS encryption. Then, enter 587 to replace the default port number, which is set to 25.

  • If your e-mail account is the type that requires registration, you must register it the first time you sign in to Outlook Web App. Connecting to your e-mail account through POP3 or IMAP4 will fail if you haven't registered your account through Outlook Web App. After you sign in to your account, sign out. Then try to connect using your POP3 or IMAP4 program. For more information about how to sign in to your account using Outlook Web App, see How to Sign In to Your Email Using a Web Browser. If you have trouble signing in, see FAQs: Sign-in and Password Issues or contact the person who manages your e-mail account.
