Learn how to use Outlook Web App to find POP3 and IMAP4 settings for Office 365 for business and Microsoft Exchange-based email.
If you’re using Office 365 for business or other Microsoft Exchange-based email, you can find your Post Office Protocol 3 (POP3) and Internet Message Access Protocol 4 (IMAP4) server settings by using Outlook Web App. Connecting to your Office 365 for business or other Microsoft Exchange-based email account using POP3 and IMAP4 only lets you send and receive email. You can’t access your contacts, tasks, or calendar when you connect to your account using POP3 or IMAP4.
Tip For the best experience, we recommend that you connect to your Office 365 for business or other Exchange email account using Outlook Web App, or through an email program that supports richer connections to Exchange such as Outlook 2013, Outlook 2010, and Outlook for Mac 2011, Apple Mail 10.6 Snow Leopard, Apple Mail 10.7 Lion, or Entourage 2008 Web Services Edition.
