I am Thomas Stensitzki, and I 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 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”. The second edition, “Exchange – Das Handbuch für Administratoren,” has been available since fall 2022.
