There are several service benefits of Microsoft 365 that can entice users to migrate from Exchange 2019 to Office 365:

Cloud-based Infrastructure: Microsoft 365 is a cloud-based service, meaning that all of your emails and data are stored in the cloud, rather than on your local servers. This provides several benefits, including reduced costs for hardware and maintenance, as well as increased scalability and flexibility.

Anywhere, Anytime Access: With Microsoft 365, you can access your email, contacts, calendar, and other data from anywhere with an internet connection. This means that you can work from home, on the road, or anywhere else, and still have access to your important data.
