This article is part of my migration from my old Office 365 to my new Microsoft 365 Tenant. It is also about setting up Office 365, the other Microsoft 365 topics will follow later. I also have written this article intentionally so that it can also be used for setup outside of a migration scenario. Part 1 was about choosing the right edition, setting up the account and configuring the domains and DNS.
