Exchange Server 2007

The tables in this section provide build numbers and general release dates for each version of Microsoft Exchange Server 2007.

Note: The version information for Exchange Server 2007 SP1 is displayed correctly in the Exchange Management Console, in the Exchange Management Shell, and in the About Exchange Server 2007 Help dialog box. However, after you apply Exchange 2007 SP1 to an Edge Transport server that's running the RTM version of Exchange 2007, the version information for the Edge Transport server isn’t updated in the Exchange Management Console unless the Edge Transport server is resubscribed to the Active Directory site. This is because the Edge Transport server doesn’t directly update Active Directory by using any configuration information. Instead, the version information for Edge Transport servers is recorded in Active Directory during the creation of an Edge Subscription.

To view the build number of an Exchange 2007 server, run the following command in the Exchange Management Shell:
