Lionel Traverse

After studying mathematics at the french University of Paris-Saclay, I switched to the world of IT with Microsoft to become a Microsoft certified trainer on Windows Server, Active Directory, and above all, Exchange Server since the first version of the product.

I then began a career as a consultant/expert on Microsoft topics, working as a subcontractor for COMPAQ and HP Services for many years. In 2015, I switched to Microsoft 365 Cloud topics, covering Exchange Online, Azure AD Entra, security and application interoperability.

Passionate about these technological topics, migration aspects, security, and the services provided to users, I have participated in numerous projects for large accounts in military, telecom, health and especially banking sectors.

In addition to my professional activities, I write articles here on concrete topics I have encountered during my service delivery assignments, which I believe deserve detailed explanations to help anyone who may face the same challenges.
