Exchange server 4.0 was the first version that was supposed to be the successor to Microsoft mail 3.5. Exchange server uses a proprietary protocol called MAPI to talk to email clients, but later added support for POP3, IMAP, and EAS Microsoft charges a monthly service fee instead of the client access licenses customers purchase in the on-premises form. Microsoft had sold a number of simpler email products before, but the first release of Exchange was an entirely new X.400-based client–server groupware system with a single database store, which also supported X.500 directory services.
Microsoft recommends that active-active mode shouldn’t be used anymore because of performance issues. Active-active mode clustering is no longer supported with Exchange Server 2007. Despite Microsoft’s description of this set-up as a “Shared Nothing” model, the data can be seen as a single point of failure. This void has been filled by “site resilience” solutions, such as asynchronous data replication.
Exchange server 2007 introduces new terminology and configurations that address the weaknesses of the previous shared data model. This type of cluster can be deployed in a single data center for protection against site-wide failures such as natural disasters. It is intended to provide protection against local storage failures by allowing for data replication to an alternative drive attached to the same system. There is an additional high-availability feature called SCR in the service pack.
The database availability group is a concept introduced by Microsoft. Evolution, Hiri and Microsoft Outlook are capable of using Exchange server’s proprietary features. POP3 and IMAP4 protocols can be used to access e-mail hosted on an Exchange Server.
Outlook Express supports email standards that are better than Windows Messaging, so it was discontinued. Push email is supported by Exchange server 2003 Service Pack 2, but not by Apple’s native Mail app on macOS. There are hybrid implementations that allow for staggered email migration and are popular for organizations that are unsure of the need to do a full transition to Exchange Online. In addition to using replica data to report cloud user experience, hybrid tools can cover the main stack of Microsoft Exchange.
The vulnerability was discovered and exploited in February 2020 using a default setting that allowed attackers to run arbitrary code with system privileges, only requiring a connection to the server as well as being logged into any user account which can be done throughcredential stuffing. The View State is used to temporarily preserve changes to an individual page as information is sent, and the exploit relied on all versions of Microsoft Exchange to use the same static validation key.
By requesting the session ID of the user and the correct View State from the server, the correct View State can be deserialised and then modified to include arbitrary code. Thousands of organizations have been affected by hackers who use these techniques to steal information. The email systems of an estimated 250,000 global customers, including state and local governments, policy think tanks, academic institutions, infectious disease researchers and businesses, were affected by the attack. In a separate incident, an ongoing brute-force campaign from mid-2019 to the present, attributed by British and American security agencies to the GRU, uses publicly known Exchange vulnerabilities, as well as already-obtained account credentials.
Can I run Exchange 2016 on a Server 2019?
Exchange 2016 is not supported to be installed on Windows server 2019. Exchange deployment assistant can be used to deploy Exchange on a Windows server.

What are the 7 new features in Exchange Server 2019?
- Key Exchange 2019 features. Meta Cache Database (MCDB) Dynamic Database Cache (DDC) Search index. Windows Server Core. Calendar extensions. E-Mail Address Internationalization (EAI)
- Remote functions in Exchange 2019: Unified Messaging.
- More Microsoft enhancements to Exchange 2019.
- Requirements for Exchange 2019.
Exchange can be used in combination with Windows server core to provide more protection against attackers. For example, admins can block access from outside directly using the server without having to use an additional firewall, because they only allow certain addresses. Microsoft has provided better support for modern hardware since the Exchange changes focus on improving memory.
What are the features of Microsoft Exchange?
- Collects Your Contacts in One Place.
- Data Loss Prevention Features.
- Apps for Office Integration.
- Single Interface for eDiscovery.
- Quick Management of Messaging Systems.
- Save Most Important Data in One Place.
- Move to the Cloud Your Way.
- User Collaboration.
It can lead to a decrease in productivity, compromised data security, and wasted time and budget spent on IT if email communications are disorganized. It allows users to find the same person across networks and collect their data on a single card. Users can’t send sensitive information to other people if they use the DLP features.
An extension model allows users to use a more powerful communication tool. This will speed up the process of managing Microsoft Exchange by allowing your specialist users to perform specific tasks. Exchange Archiving, large mailboxes and retention policies allow you to control your storage and compliance demands while keeping your users productive. You can either on-board to the Cloud overnight or manage a hybrid deployment with mailboxes on-premises and online.
Microsoft Exchange gives your users touch-enabled inbox on the Outlook desktop, as well as the browser and mobile interface.
What are the new features in Exchange Server 2016?
- Improved search experience.
- New cloud-focused architecture that supports mobility.
- Easier collaboration on SharePoint and OneDrive.
- Faster failover and failure isolation.
- Outlook on the web and Outlook app feature enhancement.
According to Microsoft Technet article, Exchange server 2016 has been made to be more efficient and effective in failure isolation compared to its predecessor. The protocol that Outlook uses to communicate with Exchange changed to MAPI over HTTP, increasing the connection reliability and stability. When a user of Exchange 2016 receives an email with a document attachment, it will be saved to a cloud-based storage service.
Exchange 2016 improves the way users saving and uploading files to OneDrive for Business and it supports editing of the attachment directly if it is integrated with Office Online server. Exchange 2016 has reduced the time required for failover due to improved transaction log code and the passive database.
Monitoring and recovery features are more than just a way to keep up component uptime, they’re also a way to alert the administrator to restore services if the server goes down. With a single click of a button, the inbox panel now has the most optimal view for reading and easy to take actions such as archive, deletion or moving a message.
Iperius can back up all calendars, activities, and contact lists, and also restore them, keeping all attributes.
