Is the Exchange Server Quota Message Service tool which is available for Exchange 2003, available or compatible with Exchange 2007. The functionality provided by the new Set-SystemMessage command for customising the quota messages does not appear to give us the same depth of customisation as the Quota Message Service. Or are there parameters that can be entered in the text string that would allow the message to include the variables for "Current Mailbox Size", "Difference if any between warning threshold and current mailbox size" etc. Any help or insight greatly appreciated Regards IAn
