MVP Office Servers and ServicesMy name is Thomas Stensitzki and work as a principal technology consultant focusing on the Microsoft messaging and collaboration technologies. I am the owner of Granikos GmbH & Co. KG. My company provides enterprise consulting and training services for Microsoft Exchange, Office 365, Hybrid Configurations, and Modern Collaboration.


Since April 2018 I am a MVP for Office Apps & Services.

I hold Master certifications as Microsoft Certified Solutions Master Messaging and as Microsoft Certified Master for Exchange Server 2010. This makes me a subject matter expert for any messaging topic related to Microsoft Exchange, Exchange Online, Microsoft 365, and hybrid configurations. When not working as a consultant I teach Microsoft technology courses as a Microsoft Certified Trainer.

I am an MCT Regional Lead, supporting the MCT community in Germany, and working closely with Microsft on training and certification topics.


In February 2019 my first book "Exchange Server 2019 - Das Handbuch für Administratoren" was published.
