In this post, we will learn the steps to create a new Mailbox Database in Microsoft Exchange Server 2019.

After installing the Exchange Server, the next step is to create a new mailbox database to store different types of mailboxes and related data.

What is Mailbox Database in Exchange Server?

A Mailbox database is a storage to store mailboxes and related data in Exchange Server 2019. Mailbox databases store data that is private to an individual mailbox and contain mailbox data and folders for that mailbox.

A mailbox database is stored as an Exchange database (.edb) file. However, .edb is not the only file related to the mailbox database. Exchange Server uses the set of data files to store and maintain the mailbox database like log files, reserved log files, and checkpoint files.

With the Fresh installation of Exchange Server 2019, a default mailbox database is created automatically in default Exchange installation location.

We can use the Exchange Admin Center (EAC) and Exchange Management Shell (EMS) to create the Mailbox Database in Exchange Server 2019.
