In the following example the first command uses the Set-User cmdlet to set the
Manager attribute on user account John Doe to his manager Jane Doe . -ma is enough information for
the shell to interpret the parameter name Manager so the command succeeds. In the second command,
-po is being used to refer to the PostalCode parameter. However, -po is ambiguous and also matches
parameter PostOfficeBox . In this case the command fails with the error shown Figure 1 - 10 .

The solution is to provide enough of the parameter name to make it unique, in this case posta would be
enough to disambiguate PostalCode from PostOfficeBox .
Discovering Commands and Getting Help
Now that you have learned the basic concept of using cmdlets, we ??™ ll discuss how to go about
discovering cmdlets and learning how to use them.
Even with more than 500 cmdlets in Exchange Management Shell, finding the right cmdlet to accomplish
a task is easier than you might think. Earlier in this section you learned that a cmdlet ??™ s name is typically
descriptive of the cmdlet ??™ s purpose. Using this knowledge along with some simple commands, you can
quickly and easily find any cmdlet.

Windows PowerShell provides powerful built - in help information available directly from the command
line.
