Outlook 2016 for Mac supports several account types. For email accounts, the most common types are Microsoft Exchange account, POP, and IMAP. Some features in Outlook require an Exchange Server account. Exchange Server includes calendaring software, email, and a place to manage your contacts. Many small, medium, and large organizations use Exchange and some email providers have Exchange accounts for home and personal accounts.

To review the type of accounts that are set up, do the following:

1. On the Tools menu, click Accounts.

2. In the left navigation, the type of account is listed and then below that is the email address associated with the account.

   An Exchange account appears as Microsoft.
