Exchange Management Shell

It may first appear as if the Exchange Management Shell is nothing more than a standard command prompt. But if you look at its prompt, you will notice that the letters "MSH" appear in brackets just ahead of the path.

The [MSH] tells you that you are not running in a true command prompt environment, but rather within a Microsoft Scripting Host shell. The Exchange Management Shell is nothing more than a Microsoft Scripting Host environment that has been extended to support Exchange Server commands.

There are many management tasks that are only performed on the Exchange Managament Shell and CANNOT be performed in Exchange Management Console. Some of them are:

• All Public Folder management.
• Give permissions to user's mailbox, entire database or the server.
• Advanced database, mailbox and recipient management.
• Advanced Transport Settings like setting a maximum message size limit for incoming and outgoing messages on the organization or connector, Set advanced SMTP connection settings etc.
• Certain Client Access settings also like set connection time-outs for POP3/IMAP4 servers (Set-IMAPSettings / Set-POPSettings), Prevent previous versions of Outlook from connecting to Exchange (Set-CASMailbox –MAPIBlockOutlookVersions), Enable/disable POP3 or IMAP4 for a user (Set-CASMailbox) etc...

Here is some collection of scripts for managing Exchange Server 2007 that are very useful for day to day operation and management.
