  • Blog Post: Generate Exchange Reports using PowerShell

    If there is one thing that has always been lacking in Exchange its a mechanism to inventory and report on your infrastructure.  Personally I think its something that should be in the Exchange Management Console, but that's a different story… The good news is that Steve Goodman has released an excellent...

I am out for most of this week without lab access so I cant test this, however I wanted...
  • Blog Post: Jetstress 2010 – Stress test problem

    Recently one of our partner has highlighted an issue in the current version of Jetstress that means the test may run in performance mode when in fact it should be running in stress mode. What's the difference between performance and stress mode? Put simply, performance mode validates the storage performance...

    All the way back in May 2009 I had just completed my Exchange 2007 Microsoft Certified Master rotation in Redmond, on my return I decided that I would write up my experience… it was actually quite emotional re-reading this post, many of the people I went through this experience with are now good friends...
  • Blog Post: Exchange Server 2010 Service Pack (SP2) is released!

    Last week when the internal announcement was made to say that SP2 had been completed and was scheduled for release, I added a few blog articles onto my “to do” list.  Imagine my surprise this morning when I woke up to find that the internets were crammed full of SP2 news and that most of the articles...
  • Blog Post: Office 365 Hybrid Configuration Certificate Planning–ADFS, Exchange Web Services, OWA, OA??

    I recently wrote about configuring Office 365 hybrid to get cross premises availability working, since that article a number of people have asked me about certificate planning. This is pretty well understood for an Exchange deployment, but what names are required for an Office 365 Hybrid configuration...
  • Blog Post: Database Maintenance in Exchange Server 2010

    If there is one area of Exchange 2010 that was poorly documented and poorly understood it has to be database maintenance.  The problem stemmed from the significant changes that we made in the store for Exchange 2010 and a confusion of terms. This has led many people in the field to get confused...

    I don't usually like posting to other peoples blogs, but the one I will make an exception for is the Exchange Team Blog.  I specifically want to raise awareness of Scott’s HA misconceptions article – not only does it clear up quite a few misconceptions, but its also a highly condensed HA primer...
  • Blog Post: Exchange Server 2010 Technical Video Series

    One thing I often do when I am learning a new area of technology is look for webcasts or recordings from TechED about that topic.  I find that it helps me understand topics much more quickly by watching a presentation and then going off afterwards and reading the deeper technical documentation once...

  • Blog Post: Analysing Exchange Server 2010 Jetstress BLG Files By Hand

    Quite often when I am working through Jetstress escalations I will ask to see the BLG files from the test.
