It was very odd at my company. We were a Google Workspace company. Gmail, Meet, Drive, etc with our own servers for messaging, gitlab and some other things. Sure being Google based isn't great either, but generally people were fine with it. Then the C suite said we were moving to Microsoft. Lots and lots of complaining, asking for justification, but no reason was given (not even cost). Today people are still cursing teams 18months later. We're not in control of our own data (things get **deleted** every time somebody leaves, and permissions are generally a mess).
