About

My name is Thomas Stensitzki and work as a principal technology consultant focusing on 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, Microsoft 365, hybrid configurations, and modern collaboration.

Since April 2018, I have been an MVP for Microsoft 365 Apps & Services.

I hold Microsoft Master certifications as 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 Microsoft on training and certification topics.

In February 2019, I published my first book “Exchange Server 2019 – Das Handbuch für Administratoren”.
