Mail Level Backup must be utilized in conjunction with full Information Store Backup as Mail Level backup for Microsoft Exchange Server is not designed to fully protect an Exchange Server, but to facilitate easy backup and fast restoration of individual emails, contacts, calendars or public folder, etc.
%edition_name% supports standalone backup option and Database Availability Group (DAG) backup option for Exchange server mail level backup.
This advisory will explain the supported protocol for the Microsoft Exchange Server 2013. It will also discuss the difference of the old and new protocol to allow users to understand more effectively.
Microsoft Exchange Server 2013 mail level backups which uses the protocol Messaging Application Programming Interface (MAPI) will no longer be supported as of MS Exchange 2013 Cumulative Update 23 and later due to limitations and functionality issues with MAPI, instead this will be replaced by EWS API.
MAPI is a client protocol that lets users access their mailbox by using Outlook or other MAPI email clients originally designed by Microsoft in 1987.
EWS API is a newer protocol that allows programmers to access Microsoft Exchange items such as calendars, contacts, and email.
Both are protocols introduced by Microsoft intended for client applications to access information stored in MS Exchange. However, due to limitations with MAPI, it will be replaced by the EWS API.
