You do this by keeping the limits the same in all locations, or by configuring more restrictive limits where messages enter your Exchange organization. An exception to the order is message size limits on mailboxes and messages size limits in mail flow rules. Exchange checks the maximum message size that's allowed on mailboxes before mail flow rules process messages. For example, your organization's message size limit is 50 MB, you configure a 35 MB limit on a mailbox, and you configure a mail flow rule to find and reject messages larger than 40 MB.

If an external sender sends a 45 MB message to the mailbox, the message is rejected before the mail flow rule is able to evaluate the message. Recipient limits between authenticated senders and recipients typically, internal message senders and recipients are exempt from the organizational message size restrictions. Therefore, you can configure specific senders and recipients to exceed the default message size limits for your organization. For example, you can allow specific mailboxes to send and receive larger messages than the rest of the organization by configuring custom send and receive limits for those mailboxes.

However, this exemption applies only to messages sent between authenticated senders and recipients typically, internal senders and recipients. For messages sent between anonymous senders and recipients typically, Internet senders or Internet recipients , the organizational limits apply.

For example, suppose your organizational message size limit is 10 MB, but you configured the users in your marketing department to send and receive messages up to 50 MB. These users will be able to exchange large messages with each other, but not with Internet senders and recipients unauthenticated senders and recipients. At the protocol level during email transfer where the Receive connector MaxRecipientsPerMessage is enforced. There is also the mailbox level RecipientLimits , which overrides the Transport level MaxRecipientEnvelopeLimit and is also enforced during message categorization.

If the mailbox level RecipientLimits is set to unlimited the default value , then the maximum number of recipients per message for the mailbox is controlled by the Transport level MaxRecipientEnvelopeLimit. However, if the number of recipients exceeds the limit, the message is not rejected; the connection receives the error, 4.

Most mail servers understand this error and they will continue to resend the message in another connection until the message is delivered to all recipients. However, when an Exchange server relays email through another Exchange server in the same organization, the Receive connector MaxRecipientsPerMessage is bypassed.

When the message is accepted and email is sent to the categorizer, the mailbox level RecipientLimits if it is not set to unlimited or Transport level MaxRecipientEnvelopeLimit are checked. If the number of recipients exceeds this limit, the message is rejected and a bounce message is sent with the error 5. RecipLimit; too many recipients. Now, if someone sends an inbound email to recipients, the email will typically be accepted because the Receive connector limit will force the sending server to send email in 10 chunks with recipients on each message, which is lower than the transport categorizer setting MaxRecipientEnvelopeLimit.

The following list shows the types of messages that are generated by Mailbox servers or Edge Transport servers that are exempted from all message size limits except the organizational limit for the maximum number of recipients that are allowed in a message:.
