It’s best to access Office 365 email either via the Outlook Web App (OWA) or via the Outlook client, but sometimes you have no choice and must access Office 365 email with either IMAP or POP. Out of those two, my definite preference is to use IMAP because it will sync email changes with the server, while POP is more of a batch download and store interaction. And in the situation where multiple people might be accessing the same email account I definitely recommend IMAP (well, actually using Outlook exchange is best, but this is assuming you have to access the mail via IMAP or POP.)
Finding the IMAP/POP settings to use with Office 365 is actually quite simple – just follow these steps:
- Login to your Office 365 Outlook Web App at: https://portal.office.com
- Click the gear icon in the upper right corner.
- Select Mail under Your App Settings
- Select POP and IMAP under Accounts
