Let’s see how to configure Email Address Policies in Exchange Server 2019. In our last article, we activated our exchange server. The email address policy is required for emails to be sent and received emails. This guide will show how to set up an email address policy in Microsoft Exchange Admin Center and PowerShell.
Email addresses examples, For example, jamil@jamiltech.com is an email address where jamil is the name that identifies the user, an @ symbol, and jamiltech.com is an SMTP domain name. The email address policy provides mailboxes with one or more email addresses. When we install Exchange Server 2019, by default, a default email address policy is created. The default email address policy specifies an email address composed of a user alias and the forest root’s domain name. Before configuring Exchange Server 2019 email address policies, the associated SMTP domain name must be configured as an accepted domain name.
Email address policies explain the rules that create email addresses for recipients in the Exchange organization. An Email address policy in Exchange Server 2019 is basically unchanged from Exchange Server 2010.

Conclusion:
In this article, we have shared details on mail flow (email address policy configuration) after installing the Exchange Server 2019 in your organization. Once done, you can create user profiles and mailboxes in the Exchange mailbox database. Also, allow them access to log in and start using their email account for sending and receiving. If you have installed a new Exchange Server and upgraded to the newer version, you should move your mailboxes from your old server.
