The capability to store an email message for later completion and sending is a fundamental feature in Outlook. This allows users to compose emails over time, saving progress and revisiting the message before final dispatch. For example, a user might begin drafting a complex email requiring detailed information. Instead of completing it in one sitting, the user can preserve the current state of the email and return to it when all necessary data is available.
Preserving email compositions as works-in-progress provides several advantages. It facilitates the construction of well-considered and accurate messages, reducing errors and omissions. Moreover, it enables users to manage their time effectively by distributing the writing process across multiple sessions. This practice is particularly useful when dealing with time-sensitive correspondence or when gathering required information from various sources.
