My name is Jaap Wesselius and I’m working as an independant consultant in The Netherlands, focussing on Microsoft business productivity solutions with Microsoft Exchange server, Office 365, Skype for Business/Teams and identity management solutions.

After getting my Bachelor Degree in 1990 (Applied Physics) I accidentally got a job in IT on a helpdesk at Turmac Tobacco Company which later became Rothmans (if I recall correctly). Later in the nineties I worked at the Delft University of Technology and Akam Expertise. In those days I also did a part-time study ‘Informatiekunde’ at the Haagsche Hogeschool in The Hague.

Both at the University and Akam Expertise I was involved in Windows projects (NT 3.51 and 4.0) but thing really started to fly when I joined Microsoft in 1997. At first in Premier Support and later on at MCS, but in both departments I did mainly Exchange related projects. Early 2006 I left Microsoft to become an independent consultant.

Because of my work for the (Exchange) community I was awarded with an MVP award for Exchange Server in 2007, and award I still hold in 2020. I wrote a book on Exchange 2010 (A practical approach) and two on Exchange 2013 (via Apress) and one was coauthored by fellow MVP Michel de Rooij.

In the past I also did presentation for TechEd, MEC, the Quest Experts Conference and Connections, but at this moment I only do local community events which we organize ourselves (although difficult now with these Corona times).
