Microsoft Exchange’s Internal Workings


         Microsoft Exchange operates in conjunction with an Exchange server and a computer used to create individual users’ Exchange accounts. An enterprise can administer its Exchange server on-premises or in the cloud via a Microsoft 365 account. If ever, you use a Microsoft Exchange account, email messages, calendar information, and other Outlook details are typically kept in sync between your Outlook client on a computer or mobile device and the Exchange server.


           Exchange ActiveSync

This is most frequently performed via a technology called Exchange ActiveSync. When you reply to, delete, or move email on your PC, for example, the action is immediately reflected on the Exchange server and then synchronized with any additional devices you may use, such as Outlook on a mobile device. With Microsoft Exchange Server, you (or your IT support business) have complete control over the hardware and infrastructure; but, with Office 365, you do not have direct access to this. The distinction can affect your level of control over system configuration, upgrades, and alterations.

Obviously, Microsoft Exchange Server is a Microsoft-developed platform for email, calendaring, contact management, scheduling, and collaboration. It is installed on the Windows Server operating system for corporate use (OS). Microsoft designed Exchange Server to enable users to access the messaging platform via mobile devices, desktop computers, and web-based systems. Exchange Server’s telephony features support voice messages.

Thus, the exchange users can collaborate on projects by exchanging calendars and documents. So, Organizations may leverage the platform’s storage and security capabilities to archive content, execute searches, and manage compliance. Exchange Server has evolved through time to become a critical component of Office 365, a software-as-a-service product hosted in the Microsoft cloud.


Exchange Server: What Is It, and How Does It Work?


            The Exchange Server is a commercial communication tool that focuses on sending, receiving, and storing email messages. So, Exchange Server manages message traffic in addition to performing many collaborative features such as calendaring and tight integration with other Microsoft Office applications. The exchange Server is well-known for its high availability (HA) features, which assure continued service in the case of a breakdown. This section discusses how to construct paths that will allow services to continue operating even if a single server fails or the data center goes down.


What Edition of Exchange Server Is Available in 2016?

             Exchange Server 2016 includes two components: an edge transport server and a mailbox server. Using an edge transport server centralizes message flow. As a result, it protects the system from cyber threats, including spam and malware. Additionally, the mailbox server manages mailboxes and client access. Client access is responsible for security (such as authentication) and message data transfer. In contrast, Mailbox is responsible for active mailbox content and administration, the transport service, and mailbox databases.


Which Exchange Server Will Be Used in 2019?


            Exchange Server 2019 Microsoft, while Office 365 and remote working have become trendy terms in recent years, Microsoft hasn’t forgotten those of us who continue to work on-premises. That’s why Microsoft just unveiled Exchange Server 2019. In addition to this, Microsoft Exchange Server 2019 has been purpose-built to improve previous excellent editions. It features a variety of security and performance changes to improve the end-user experience.


What Differences Exist Between Exchange 2019 and Exchange 2016?



         Support for Windows Server Core:

Running Exchange on a Windows deployment with a smaller surface area means fewer components to maintain.  Whereas, a smaller attack surface area. Prevent Internet access to the Exchange administration center (EAC) and the Exchange Management Shell: Rather than complex network and firewall restrictions, you can use Client Access Rules to limit Exchange administration to the internal network.

Furthermore, Exchange Server 2019 contains substantial security enhancements for client and server communications. By default, TLS 1.2 is enabled. The default encryption configuration utilizes TLS 1.2 and disables older techniques ( DES, 3DES, RC2, RC4, and MD5). Additionally, it will prioritize elliptic curve key exchange procedures over techniques that do not utilize elliptic curves. Exchange Server 2016 and later inherits all cryptographic configurations from the operating system. Additional information is available in Exchange Server TLS Guidance.



 The Exchange 2019 offers a freshly rebuilt search infrastructure optimized for cloud scalability and dependability, similar to what is available in Exchange Online. So, this new search of architecture enables, indexing a higher number of files, easier maintenance, and faster search results.


        Significantly Quicker and More Reliable Failovers

The search architecture changes result in significantly faster and more reliable server failovers. Along with the database of Meta Caches Exchange’s, database engine has been enhanced to enable increased overall performance and the usage of cutting-edge storage technology such as larger drives and SSDs. On contemporary technology, Exchange now supports up to 256 GB of RAM and 48 CPU cores.  Dynamic database cache: The information store process allocates memory cache to match active database usage to available memory.



Calendar – Do Not Forward: This is similar to Information Rights Management (IRM) for calendar items but without the IRM configuration requirements. Nevertheless, attendees may not send the invitation, and only the organizer may invite additional guests.


Calendar – Improved Out of Office: Provides additional options for times when you are not at work. Add a Gone/Out of Office event to your calendar, along with a simple option to cancel or deny meetings scheduled during your absence.


Calendar – Remove-Calendar Events cmdlet: Indeed, it allows administrators to cancel meetings planned by a departing user. Previously, canceled meetings remained on the calendars of conference rooms and meeting attendees. Subsequently, email address internationalization (EAI) enables the routing and delivery of emails that contain non-English characters.
