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.
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.
For information about which Outlook clients are supported by Exchange 2016 and Exchange Online, see System Requirements for Office.
Office 365 is designed to work with the latest browsers and versions of Office. If you use older browsers and versions of Office that aren't in mainstream support:
- Microsoft won’t deliberately prevent you from connecting to the service, but the quality of your Office 365 experience may diminish over time.
- Microsoft won’t provide software updates to resolve non-security related problems.

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 lets users 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 selecting 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 selecting 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.
Outlook on the web also is available in mobile versions. For more information, see this page.

Exchange Online supports the Microsoft Exchange ActiveSync protocol, which synchronizes mailbox data between mobile devices and Exchange Online, so users can access their email, calendar, contacts, and tasks on the go.
A wide range of mobile devices work with Exchange ActiveSync, including Microsoft Windows Phone, Apple iPhone and iPad, and Android phones and tablets. In addition to mobile phones and devices, the Mail application in Windows Phone uses Exchange ActiveSync to connect to Exchange Online. A complete list of current Exchange ActiveSync licensees is available at the Exchange ActiveSync Licensing site.
For more information about Exchange ActiveSync, see Exchange ActiveSync.
Important
The maximum number of Exchange ActiveSync devices per mailbox is 100.
Applications developed with Exchange Web Services (EWS)

Applications developed using Exchange Web Services (EWS) or the EWS Managed API let administrators access data stored with Exchange Online from applications that are running on-premises, in Azure, or in other hosted services.
For more information on applications developed with Exchange Web Services, see Web Services in Exchange.
POP and IMAP
Exchange Online supports mailbox access through both POP3 and IMAP4 protocols. POP and IMAP access requires encryption using SSL. POP is enabled by default for all users. Users can view their POP and IMAP connection settings in Outlook on the web. Administrators can disable POP and IMAP access on a per-user basis.
For more information about POP3 and IMAP4 connectivity, see POP3 and IMAP4.
SMTP
Simple Mail Transfer Protocol (SMTP) is used to send outbound mail for clients that connect to Exchange Online through IMAP or POP. It is the primary protocol for routing and delivery through Exchange Server. Exchange Online supports two types of SMTP relay services for authorized internal customer applications that require SMTP mail submission:
SMTP message submission to users inside the managed environment.
Authenticated SMTP message relay to addresses outside the managed environment.
Important
IP addresses for authorized source servers are required to allow SMTP relay. Transport Layer Security (TLS) encryption and authentication is required when using SMTP to send email.
BlackBerry® devices
Office 365 email is available on BlackBerry® devices via Exchange ActiveSync. To find out what your options are, see these topics:
For more information, see BlackBerry.
