Exchange 2007 RTM's

Exchange 2007 released to manufacturing on Friday.  

Previously known as E12, the product delivers some great new technology including:
 
- Unified Messaging that delivers voice mail and fax messages to the Exchange inbox
- Greater mobility support – for example, IT administrators can enforce security policies on mobile devices with greater control and granularity and end-users get full fidelity HTML mail
- 64-bit architecture that allows organizations to increase the number of users per server or allow larger mailbox quotas while reducing per-mailbox storage costs
- Anti-spam that ensures mail from your contacts gets through, while keeping the bad stuff out

With over 500,000 beta testers who helped shape and strengthen it, Exchange 2007 is our most tested Exchange release ever. Hundreds of early-adopter enterprise customers are already using this product and realising great productivity gains for their information workers along with simplified management and reduced costs for IT. Internally we are running over 125,000 mailboxes on Exchange 2007 with greater than 99.95% availability.
