Question : Export-Mailbox says pst directory does not exist when it does

I have an Exchange 2010 server running properly on 64 bit Server 2008 R2 and need to export contents of mailboxes for backup.  So, I built a 64 bit Windows 7 box, installed Outlook 2010 64 bit on it and Exchange 2010 admin tools.

When run as an admin who has been granted the "Mailbox Import Export role", Exchange powershell correctly connects to the new Exchange server but when I run the command: export-mailbox -identity peter -pstfolderpath "d:\test", I get the message: "Directory 'd:\test' does not exist, please create it first and try again." when it clearly DOES exist and I have full control of it.  The D: drive is a local hard disk so no networking issues here.  The -verbose switch adds little of value to the error message.

Googling the issue reveals a lot of muddled thinking and out-of-date information concerning 32 bit workstations, Exchange 2007, etc so I thought I'd come here to the real Experts and ask if anyone knows of this problem and a solution?
