Exchange Online: Desktop Client Setup

Once an Exchange Online account has been set up, it can be accessed from a desktop or laptop computer, tablet, or smartphone. Microsoft Outlook is the preferred client for use with Microsoft Exchange. Microsoft Outlook is available for Windows, macOS, iOS, Android OS, and through a web browser. Some features, such as online archiving, will not work in non-Outlook clients.

Microsoft announced changes to its higher educational licensing in August 2023, effective mid-2024, that will affect Microsoft OneDrive, Exchange email, Teams, and SharePoint storage limits. Please take steps to eliminate large email messages that you don't need from your Microsoft Exchange account.
