The benefit of using this command is that it enables organizations to manage and optimize their email communication by imposing size limits on outgoing messages.

When customizing the maximum send size on a per-mailbox basis, administrators can prevent the transmission of excessively large attachments, which can impact email server performance, network bandwidth, and recipient mailboxes. This helps maintain efficient email flow, prevents unnecessary resource strain, and ensures that email services remain responsive and reliable.

By tailoring the maximum send size to individual mailbox requirements, organizations can strike a balance between facilitating effective communication and safeguarding system performance.
