At Microsoft we have challenges around messaging protection just like other organisations. But unlike other organizations we are the target of many more advanced attacks from outside the company.  So our internal IT department was looking for a solution to help with this increasing problem.  Exchange Server 2007 has been deployed since 2006 and marks the last major upgrade to a traditional messaging infrastructure.  The diagram below shows what this looks like using Hub transfer servers in our corporate forest and Edge transport servers in our Extranet.

So we are constantly looking to stay ahead of the bad guys and moving to Exchange Hosted Services was a step in that direction.  The diagram below shows this a more simple approach with all the necessary protection happening in the cloud using the hosted service.

This is pretty cool and kind of shows where we are going with our Software+Services vision.  To find out more about this check out the Technical Case Study on the IT Showcase website.

  • I would be interested in hearing how you handle the authentication and mail flow between the four different internal Exchange Organizations and also why you continue to use the Edge Transport role alongside EHS.

  • Hi Michael,

    I spoke to our local IT folks and this is what they had to say.

    "It’s primarily to do with us needing to run both in our enterprise so we can give customers real world feedback on how to run either in their environment.  It’s nothing to do with us feeling we need both to have proper protection.  Either one is perfectly affective for filtering spam and virus’ stand alone".

    Does that make sense?

  • Sure does. I had a feeling that was the reason. :)
