Whole message size limits : Specifies the maximum size of a message, which includes the message header, the message body, and any attachments. Exchange uses the custom X-MS-Exchange-Organization-OriginalSize: message header to record the original size of the message as it enters the Exchange organization.
Whenever the message size is checked, the lower value of the current message size or the original message size header is used. The size of the message can change because of content conversion, encoding, and transport agent processing. For any message size limit, you need to set a value that's larger than the actual size you want enforced.
This accounts for the Base64 encoding of attachments and other binary data. For example, if you specify a maximum message size value of 64 MB, you can expect a realistic maximum message size of approximately 48 MB. Attachment size limits : Specifies the maximum size of a single attachment in a message.
The message might contain many smaller attachments that greatly increase its overall size. However, the attachment size limit applies only to the size of an individual attachment. While you can't limit the number of attachments on a message, you can use the maximum message size limit to control the maximum total of attachments on the message.
Recipient limits : Specifies the total number of recipients that are allowed in a message. This includes the total number of recipients in the To: , Cc: , and Bcc: fields.
A distribution group counts as a single recipient. Message header size limits : Specifies the maximum size of all message header fields in a message. The size of the message body or attachments isn't considered. Because the header fields are plain text, the size of the header is determined by the number of characters in each header field and by the total number of header fields.
Each text character consumes 1 byte. The following tables show the message limits at the Organization, Connector, Server, and Mailbox levels, including information about how to configure the limits in the Exchange admin center EAC or the Exchange Management Shell. Organizational limits apply to all Exchange servers, Exchange servers, Exchange Mailbox servers, and Exchange Hub Transport servers that exist in your organization.
On Edge Transport servers, any organizational limits that you configure are applied to the local server. Organizational limits also apply to external senders and external recipients anonymous or unauthenticated senders or recipients :.
For inbound messages from external senders, Exchange applies the organizational maximum send message size limit the maximum receive message size limit as described in the Recipient limits section is applied to the internal recipient. For outbound messages to external recipients, Exchange applies the organization maximum receive message size limit the maximum send message size limit as described in the Recipient limits section is applied to the internal sender.
