Jaap Wesselius (Jaap Wesselius)
Jaap Wesselius - Exchange Server MVP & Microsoft UC Specialist
I'm working as an independent consultant, primarily focusing on Exchange server, Lync server and Office 365. I'm working with Exchange server since version 5.0 running on NT4 (first implementation in 1997, approx. 1200 seats). Since 1998 I'm also involved in hosting, starting with MCIS (Microsoft Commercial Internet System) which was later on incorporated into Exchange server. I've done all kinds of projects, greenfield, migration, hosting etc.
Besides Exchange server I'm also working with Skype for Business (Lync Server 2010/2013 in the past) and Office 365 (Exchange Online).
Mostly I do consulting work, but also do presentations on major events (MEC, TechEd, Connections, TEC) on a regular basis and I'd like to work as an author as well. I've written two books on Exchange 2010 and two books on Exchange 2013, the latest one on Managing Exchange 2013 with PowerShell.
In the community I'm active on my own blog, but also for the Dutch UC group ( and the Dutch network community (
