  • The administrator can delete such meetings that were organized by members who have left the company.
  • The email ids containing non-English characters can be routed natively.


  • Exchange Server 2019 has less surface area on Windows deployments and hence lower chances of external attacks.
  • The Client Access Rules will allow the administrator to manage the task from the internal network.
  • Now, for client and server connections, Exchange uses TLS 1.2 algorithm and disables the older ones like DES, 3DES, RC2, RC4, and MD5.


Exchange Server 2019 has elevated the properties and features of the existing Exchange Server 2016. It can allocate more space for the database, and the increased features of the security can save complete data securely.
