Exchange 2007 Message Size Limitations

In the Exchange 2007 organization environment, we can limit the message size to three tiers, organizational level (Global Settings), server level, connector level, and user level. In this article, I will use the Exchange managment Shell (EMS) for the related configuration.

Global Settings:

Global settings can be compatible with the Exchange 2003/2007 mixed environment. These settings are saved in Active Directory. When an organization is in this mixed environment, if the global configuration of E 2003 conflicts with the E 2007 setting, it depends on the strictest.

If you want to view global settings on the Exchange Transport server, you can run the following command under EMS: Get-transportconfig

If you make changes relative to this setting, you can use the following command: Set-transportconfig. For example, if you want to limit the maximum accepted message size, you can use the following command:

Set-transportconfig–maxreceivesize

Connector restrictions:

We can also make message size restrictions on Send connectors, accept connectors, and external connectors.

If you want to see the configuration that accepts connectors, use the following command:

Get-receiveconnector | List

If you want to see the configuration of a Send connector, use the following command:

Get-sendconnector | List

If you want to make message size settings for connectors, use the following command:

Set-sendconnector–identity raus–maxmessagesize Messagesizeyouwant

Note: If you have multiple send connectors on your server, use the –identity parameter to identify them.

Server Restrictions:

We can view the transport server settings through the following command

Get-transportserver | LIST

If you want to configure the server, you can use the following command:

Set-transportserver, of course, also need to add the appropriate parameters.

User restrictions:

Exchange can limit the following user levels

Mailbox-user

Mail-contact

Mail-user

Publicfolder

Distribution Group

Mailbox-user:

If you want to view an Exchange mailbox setting, you can use the command:

Get-mailbox–identity Janas | List

If you want to change the maximum send message size setting for a mailbox, you can use the command:

Set-mailbox–identity janas–maxsendsize 1038400

Mail-contact:

If you want to see a contact setting, you can use the command:

Get-mailcontact–identity Janas | List
