I have a powershell cmdlet (move-IMAPMailboxToExchange) that requires a lot of repetition to enter. I want to call it with another batch/powershell script that just takes two args from the command line. I've tried every calling convention I can think of but I can't make it work.

I want this:

Move-IMAPMailboxToExchange -SourcePassword P@ssW0rd! -allowunsecureconnection -sourceLoginId username -sourceserver source.ser.ver -sourceidentity username@mail.dom.ain targetclientaccessserver "client.access.ser.ver" -targetidentity username@mail.dom.ain -verbose

To be this:

migrate-user username P@ssW0rd!

I've tried $args, but that seems to expand. I've tried $args[0] which works in the bareword password and sourcelogin, but doesn't work next to the @mail.... I've tried %1, etc, from the old DOS days but that doesn't work.

I'm a unix dork and I'm not quite grokking powershell yet.


From what I remember, single-quotes is how PowerShell designates something as 'do not parse'. so...

You might want to do something like this


Move-IMAPMailboxToExchange [all that jazz]

As a way to firmly declare the variables within the context of the script. If you're having trouble constructing the -sourceidentity and -targetidentity variables, you may want to pre-construct them before putting them on the move-imaptoexchange command...

  • Beautiful, thanks! It correctly interpolated the variable next to the @ sign so I didn't need to make temp variables for that. – Jim Zajkowski Jun 5 '09 at 15:19

You should be able to define a function or script file around your cmdlet, like this:

    function migrate-user

Move-IMAPMailboxToExchange -SourcePassword $password -allowunsecureconnection -sourceLoginId $username -sourceserver 'source.ser.ver' -sourceidentity "$username`@mail.dom.ain" targetclientaccessserver 'client.access.ser.ver' -targetidentity "$username`@mail.dom.ain" -verbose
