Microsoft's Exchange Server 2019 Enterprise

Microsoft's mail server Exchange Server 2019 is aimed at companies and self-employed persons who want to optimize the exchange of messages by e-mail internally and externally. It is important that users have a uniform e-mail address and that security-relevant points are set up, such as the maximum number of e-mails to be received and sent per user. Also adjustable are folders and their permissions for Outlook. With the Exchange Server 2019 Enterprise, Microsoft is primarily targeting small and medium-sized companies. The additional support of all common output devices such as smartphones and tablets gives companies and freelancers an unbeatable competitive advantage in the field of communication, which is otherwise reserved for corporations. With a planned configuration there is no need for permanent maintenance. Exchange is designed for continuous operation. The versions from Exchange 2008 and 2010 onwards have proven that this works reliably.
