Migrating an on-premises Exchange environment to the cloud can be complicated, it can be time-consuming, and there are a variety of factors that prompt companies to keep some portion of their Exchange environment on-line – i.e., they deploy a hybrid configuration. Hybrid configurations are popular, especially with larger customers.

There are some things to keep in mind, however.
First, users typically have to choose one means or another – i.e., an on-premises Exchange user can’t have archives both in the cloud and on-premises (but they can choose cloud).
Finally, any enhancement tools that customers choose – such as compliance archiving, email security, or backup – need to work with hybrid environments. Barracuda products do, but the same isn’t always true with other vendors.
