The framework for legally deploying and using Microsoft Exchange Server or Exchange Online, based on server and client access models.
Exchange Online Plan 1 is designed to work with various clients, including the Outlook desktop client. However, the Microsoft 365 Family Plan is primarily intended for personal use and does not include the rights to connect to Exchange Online. Therefore, while you have the desktop version of Outlook, you would not be able to connect it to Exchange Online using a Microsoft 365 Family Plan license.
