Exchange 2007 RAM recommendations updated

Microsoft has updated the recommended amount of RAM for Exchange 2007 mailbox servers.

Minimum: 2 GB of RAM
Recommended: 2 GB of RAM per server plus 5 megabytes (MB) of RAM per mailbox

This was previously 10MB per mailbox. Unlike Exchange 2003, though, more RAM will improve performance by reducing the IOPS requirements. More on this after the Exchange Connections conference, or if you are there, attend the keynote.
