The new Exchange tries to simplify the software's architecture while still adding new features and working better with other Office products. You can now use links from Sharepoint 2016 and OneDrive for Business as email attachments, instead of having to upload the actual file, leading to more robust file sharing and editing. Add-ins have been introduced, which allows extensibility similar to extensions on a web browser. Microsoft is providing a 180-day trial for free.
