Microsoft Outlook

Microsoft Outlook is an email program that includes support for calendar, contacts, tasks, and the following key features:

  • MAPI over HTTP Messaging Application Program Interface (MAPI) over HTTP allows Outlook users to connect to Exchange Online mailboxes over the Internet from outside their organization's firewall. MAPI over HTTP, the long term replacement for Outlook Anywhere. This connectivity method offers improved connection resiliency, more secure sign-in, extensibility, as well as enhancements for IT and support. To learn more, see RPC over HTTP reaches end of support in Office 365 and MAPI over HTTP.

  • Autodiscover The Autodiscover service feature automatically configures Outlook to work with Exchange Online. Outlook users can receive their required profile settings directly from Exchange Online the first time they sign in with their email address and password. These settings automatically update the Outlook client with the information necessary to create and maintain the user's profile. An SSL certificate is required to use the Autodiscover service. This SSL certificate is limited to a single primary SSL domain.

  • Cached Exchange Mode The Cached Exchange Mode feature allows Outlook users to access local copies of their Exchange Online mailboxes when they are not connected to the Internet. Cached Exchange Mode retains a client-side copy of users' Exchange mailboxes in Outlook and automatically synchronizes this copy with the email server. We recommend using Outlook in Cached Exchange Mode because it provides offline access and helps to provide a responsive user experience even when network conditions between the client and the server are not ideal.

Mail Support. All the topics, resources, and contact options you need for the Mail app on your iOS devices and Mac. Look up your Mail settings. Follow these steps if the Mail app on your Mac suddenly doesn't send or receive email. Get help with Mail.

By default, Outlook access is enabled for all users. Administrators can disable access for specific users or groups through Windows PowerShell. We recommend using the latest version of Outlook—with the latest service pack installed—to access Exchange Online.

Outlook is not provided as part of the Exchange Online subscription price. Microsoft Office Pro Plus (which includes Microsoft Outlook) is included in some Office 365 plans and can be purchased as a separate subscription. You will see the following limitations if you use POP to connect to an Exchange Online email account: > No calendar information > No free/busy information > No Global Address List > No push email > When connecting through POP, all messages will be downloaded to the client and there will be no synchronization between multiple computers or devices (such as between a laptop and a phone).

Outlook on the web

Outlook on the web is a web-based version of the Outlook email program that is used with Exchange Online. It enables users to access their email, calendar, and contacts through a web browser from wherever they connect to the Internet. For information about supported browsers, see Supported browsers for Outlook on the web for business.

Outlook on the web comes in two client versions, both of which can be used with Exchange Online:

  • Outlook on the web The standard version of Outlook on the web provides Exchange Online users with a messaging experience most similar to that of Outlook users. It supports most newer web browsers and is optimized for use on tablets and smartphones as well as desktops and laptops. Users can read and send messages, organize contacts, and schedule appointments and meetings. The default activity-based time-out is set at six hours, but it can be configured by an administrator in Windows PowerShell from 5 minutes to 8 hours. This time-out depends on user interactions within the web app, such as clicking a button or selecting a message. There is also a separate security-driven time-out, which is not configurable and will occur regardless of user activity. If a user is logged in for 8 hours, OWA will automatically log the user out and ask for re-authentication.

  • The light version of Outlook on the web The light version of Outlook on the web provides Exchange Online users access to the mailbox using almost any web browser. Users can read and send messages, organize contacts, and schedule appointments and meetings. The default activity-based time-out is set at six hours, but it can be configured by an administrator in Windows PowerShell from 5 minutes to 8 hours. This time-out depends on user interactions within the web app, such as clicking a button or selecting a message. There is also a separate security-driven time-out, which is not configurable and will occur regardless of user activity. If a user is logged in for 8 hours, the light version of OWA will automatically log the user out and ask for re-authentication.
