My name is Michel de Rooij and I’m a Consultant in the Exchange, Office 365, and PowerShell space.

After my bachelor study Computer Science, I started my professional career as a 3/4GL developer (Clipper, Powerbuilder). I became more interested in infrastructure technology and at some point I got the opportunity to make the professional switch to infrastructure.

Since then, I have participated in many projects that range from client migrations to designing infrastructure architecture, but for years my work experience is now related to Exchange, or more recently Office 365. My background as developer helps with all the PowerShell goodness, as most Exchange projects require a certain amount of scripting, or ideas on how to create tools to support solutions or migration projects.

I currently hold the following IT related certifications (older certifications condensed):

  • MCSE: Messaging on Exchange Server 2013
  • MCSA: Windows Server 2012
  • MCTS: Office Communications Server 2007, Configuration
  • MCTS: Microsoft Exchange Server 2010, Configuration
  • MCITP: Enterprise Messaging Administrator 2010
  • MCTS: Windows Server 2008 Active Directory: Configuration
  • MCTS: Windows Server 2008 Applications Infrastructure: Configuration
  • MCTS: Windows Server 2008 Network Infrastructure: Configuration
  • MCITP: Designing/Deploying Messaging Solutions w/Microsoft Exchange 2010
  • MCTS: Microsoft Exchange Server 2007: Configuration
  • MCSE: Messaging 2000/2003
  • MCSE: NT4/W2000/W2003
  • MCSE + Internet
  • Prince2 Foundation
  • ITIL Essentials

For those examples I could have picked any names, but instead I borrowed them from the comics series Blake and Mortimer, created by the late Edgar P. Jacobs.

What’s with this name, EighTwOne? Well, I had to make up a name as all the variations on mistermail, exchangeguy and deliverydude were already taken. So, used the original RFC number for SMTP, which was RFC 821, and wrote that down: eight two one. Then I noticed matching letters between words, so I left them out keeping only 1 letter in uppercase (for readability). So, RFC 821 became eight two one became EightTwoOne and ended up in EighTwOne. Mystery solved.
