New-MailboxExportRequest - Not Working when selecting specific folder

Hello,

I am using the new-MailboxExportRequest command to export only the "Contacts" folder.  It is not working.

Environment - Exchange 2010 SP3

Powershell command = New-MailboxExportRequest Donald -filepath \\mb01\export\donald.pst -includefolders "contacts"When running the above command, only the recoverable items export.  I tried the above with "#contacts#" with no luck as well.

Am I missing something?

Thanks

Ron
