Issue:
You would like to change the limit for an e-mail's message size in Exchange.
Solution:
2007 Exchange:
In MS Exchange Server 2007 SP 1, changes to the organization limits are automatically copied to the corresponding global limits below. In Exchange 2007 SP1, you can modify the organization limits (and thereby the global limits) via the Exchange Management Shell Set-TransportConfig command. The limits can also be edited in the GUI again.
The organization Set-TransportConfig has the following parameters you can set:
MaxReceiveSize
- default value in 2007 SP1 = 10 MB
MaxSendSize
- default value in 2007 SP1 = 10 MB
MaxRecipientEnvelopeLimit
- default value in Exchange 2007 SP1 = 5000 recipients
AttachmentSizeOver
- not yet configured
Examples:
Start --> All Programs --> Microsoft Exchange Server 2007 --> Exchange Management Shell
Get-TransportConfig (displays current limits)
Set-TransportConfig -MaxSendSize 20MB -MaxReceiveSize50MB -MaxRecipientEnvelopeLimit 1000 (sets 20MB for received messages, 50 MB for sent, and 1000 as number of recipients limit).
Get-TransportConfig (redisplays current limits to verify changes okay)
For Exchange Server 2007 SP1, Microsoft put the settings back in the GUI (Exchange Management Console):
1. Expand Microsoft Exchange
2. Expand Organization Configuration
3. Expand Hub Transport
4. Within Global Settings tab, right-click Transport Settings and select Properties.
5. In the Transport Settings Properties dialog, set Maximum receive size (KB) and Maximum Send Size (KB) fields.
6. Click OK and Save the dialog.
To update the Send Connectors limit:
1. Follow steps 1-3 above.
2. Click the Send Connectors tab.
3. Right-click the desired Send Connector, and select Properties.
4. In the connector settings properties dialog, under the General tab, set the Maximum message size (KB) field.
5. Click OK and Save the dialog.
