Microsoft 365 - Choosing a Client

A "client" is an application that you use to access and manage your email and calendar. Examples include Outlook on the web -- the interface you can use to access Office 365 using a web browser -- or desktop clients like Outlook. To better prepare for and interact with Office 365, select a client that meets your needs.

Important: For the best experience with Office 365, Microsoft recommends connecting via Exchange protocol via Outlook M365/O365/ProPlus/2021/2019/2016, Outlook App for iOS/Android, or connecting to Outlook on the web via recommended/supported web browser. In addition to Exchange/Active Sync protocols, Office 365 also supports IMAP/POP3 protocols but with limited functionality. Please refer to the Supported clients/protocols document for further information.

Question: Will you primarily be using Office 365 for email only, calendar only, or both email and calendar?

Based on your answer to the above question, we have the following recommendations regarding which client to choose:

Mail Only	Calendar Only	Mail and Calendar
