The Microsoft Exchange Server 2007 shell commands in the following table will be quite useful when you're initially setting up your Exchange Server and when your company or department organization changes. Keep this list handy to make you job go more quickly and smoothly.

Command Description
Get-ExchangeServer Obtains the attributes of a specified server. The cmdlet obtains the attributes of all the servers in the Exchange organization when you don't provide a specific server name.
Set-ExchangeServer Sets generic Exchange attributes in Active Directory for a specified computer. This cmdlet works only with Exchange Server 2007. You can use this task on only one server at a time. Use scripts to perform bulk management tasks.
Enable-ExchangeCertificate Enables or disables a certificate contained in a local certificate store. Certificates provide the means for secure e-mail communication between client and server.
Export-ExchangeCertificate Creates an external file containing the Exchange Server certificate. You can use this cmdlet to create a copy of the certificate for later restoration.
Import-ExchangeCertificate Places a digital certificate contained in an external file in the local security store. The server can then use the certificate to secure e-mail communication.
Get-ExchangeCertificate Displays a list of Exchange Server certificates in the local security store.
New-ExchangeCertificate Creates a new self-signed certificate you can use for test servers. This cmdlet also makes it possible to create a certificate request for Transport Layer Security (TLS) and Secure Sockets Layer (SSL) services.
Remove-ExchangeCertificate Deletes any Exchange Server certificate in the local security store. This option doesn't provide any form of undo, so make sure you export the certificate using Export-ExchangeCertificate before you use this cmdlet.
