Office 365 – Hybrid Configuration Wizard (HCW)

Whilst working on a few O365 engagements over the last month or so I have seen various issues that have been caused by on-premise infrastructure/setup and which have not allowed the HCW (which was introduced in Exchange 2010 SP2) to complete successfully. These issues range from not correctly publishing autodiscover to not having the correct…

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 about what…

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 during a migration? Certificate Requirements in Office 365…


Microsoft Certified Master Exchange Server –2 years later…

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, which…
