Salient Features of Microsoft Exchange Server 2016
The major change in Exchange Server 2016 is server role. In Exchange 2013, there were three roles, Mailbox server role, Client Access server role and Edge Transport server role. Exchange 2016 have just two server roles, Mailbox server role and Edge Transport server role.
•Mailbox Server Role: Mailbox server role in Exchange 2016 compared to Exchange 2013 includes both Mailbox server role and Client access server role. This simplifies the installation and management of Exchange 2016.
•Edge Transport Server Role: Edge Transport server role is similar to Transport role in Exchange 2013. It is installed in DMZ network and provides anti-virus and anti-spam functionality.
•Outlook on the web (aka Outlook Web App): Outlook on the web is now updated with new web interface with faster email and people search.
•MAPI over HTTP: MAPI over HTTP was introduced in Exchange 2013. It is now the default protocol that Outlook uses to communicate with Exchange server. Exchange 2016 also supports Outlook Anywhere (RPC over HTTP) and is the fall back option for clients that do not support MAP over HTTP. If you are installing Exchange 2016 in existing Exchange 2013 environment then MAPI over HTTP will not be used by Outlook clients, instead Outlook Anywhere will be used.
Document Collaboration: Exchange 2016 with SharePoint2016 allows Outlook on the web users to link and share documents stored on One Drive for business or on premise SharePoint server instead of attaching the files. If you are running Office Online Server on premise, you can edit documents using Outlook on the web.
