What Outlook can provide for sharing calendar information with friends, acquaintances of colleagues, or business associates depends on whether the software is used as a stand-alone application, as part of the Microsoft 365 online service, or in combination with an exchange server.
While Microsoft 365 provides various Office applications as an online service in the cloud, Outlook is a locally-installed desktop application. In the private sector, it is primarily used as an e-mail program that allows users to manage different e-mail accounts through the same user interface. Within an organization, however, Outlook usually acts as a client program for the Microsoft Exchange Server, a central repository for e-mails, appointments, and tasks.
Below, we will provide you with a guide to the different sharing functions the Outlook desktop application provides, as well as the Microsoft 365 App calendar.
