可以使用 EAC 和命令行管理程序以配置用户邮箱的邮件大小限制。这些限制控制用户可以发送和接收的邮件的大小。默认情况下，创建了邮箱时，系统不会对发送和接收的邮件的大小进行限制。You can use the EAC and the Shell to configure message size limits for a user mailbox. These limits control the size of messages that a user can send and receive. By default, when a mailbox is created, there isn't a size limit for sent and received messages.
请记住，Exchange 组织中还有其他设置能确定邮箱发送和接收的最大邮件大小(例如，在邮箱服务器上配置的最大邮件大小)。若要了解有关 Exchange 中邮件大小的限制(包括邮件大小限制类型、作用域和优先顺序)的详细信息，请参阅邮件大小限制。Keep in mind that there are other settings in an Exchange organization that determine the maximum message size a mailbox can send and receive (for example, the maximum message size configured on a Mailbox server). To learn more about the message size restrictions in Exchange, including the types of message size limits, their scope, and the order of precedence, see Message size limits.

还可以控制邮件用户发送和接收的邮件的大小，以及来自共享邮箱的邮件的大小。You can also control the size of messages sent and received by mail users and from shared mailboxes.
