The quantity of data that can be transferred through electronic messages is a critical consideration for efficient communication. Within the Microsoft 365 ecosystem, a specific parameter dictates the maximum size of attachments and the overall message itself. This parameter ensures system stability and optimal performance for all users. For instance, attempting to send a message exceeding this established value will result in delivery failure, and a notification will be sent to the originator.
Adherence to this data transmission boundary is essential for several reasons. It prevents mail servers from being overloaded with excessively large messages, contributing to a smoother user experience for everyone. Furthermore, it discourages the practice of transmitting large files via email, which is generally less efficient than utilizing dedicated file-sharing services. Historically, such limitations have been necessary due to bandwidth constraints and the processing capabilities of email servers.
