Shulou(Shulou.com)06/02 Report--

I had a discussion with my partner about whether Exchange Server 2016 is the end point of the mail system version in terms of local mail solutions. Most peers think it is gone, the final version of Exchange 2016. After all, we are now advocating a "mobile first, cloud first" strategy.

Exchange 2019 is released to Exchange product lifecycle extension.

Exchange Server 2019 is now available and can be downloaded from the Volume Licensing Service Center

As with the previous release of the latest version of Exchange Server, it provides some new features, services and technologies. In this article, we will discuss the new features and technologies brought about by Exchange 2019.

Security.

From a security perspective, the most obvious change is that Exchange Server 2019 supports Windows Server Core. Support for the server core means more secure deployment and less risk.

Exchange Server 2019 also allows you to block external access to the Exchange Management Center and the Exchange Management Shell (Shell).

Performance

Exchange Server 2019 has a new search infrastructure that can index larger files and improve search performance. In addition to better search performance, management is easier.

Exchange Server 2019 also provides faster and more reliable DAG failover services. For large deployments and large databases, this improvement is more obvious and has advantages.

Exchange 2019 now supports up to 48 CPU cores and up to 256GB RAM.

Dynamic database caching (DDC) applications ensure that database DB installed by active nodes gets more allocation caches while reducing allocation to passive database caches, which is significantly different from previous Exchange Server versions, which allocated the same number of caches to both active and passive databases.

End user

1) No forwarding function, which is used to prevent calendar invitation attendees from forwarding invitations to others. Instead, only the meeting organizer can invite others.

2) Calendar out-of-office features, such as the ability to add events to the calendar, can show you leaving or leaving the office, and you can quickly cancel or reject meetings that occur when you are out of the office

3) add remove-calendarevents cmdlet, which allows administrators to cancel meetings scheduled by users.

4) Exchange 2019 also introduces Add-FolderPermissions cmdlet. Using this cmdlet, it is easier for administrators to assign delegate permissions through PowerShell.

5) by merging email address internationalization (EAI), Exchange 2019 can now route and locally deliver e-mail messages to addresses that contain non-English characters (multinational organizational structures are useful)

The Exchange Server 2019 prerequisite requires the installation of the Windows Server 2019 OS system, and it is officially recommended that Exchange Server 2019 be installed on the Windows Server 2019 Core. Windows Server 2019 Core provides a more secure platform for mail systems. However, there are some problems with uninstalling at present, so it is recommended to use the command to uninstall.
