User mailboxes in Exchange are associated with real users, with one mailbox for each. Each mailbox has an associated Active Directory account that gives the user access to the mailbox for sending and receiving email messages and create tasks and appointments.

So, when administrators create a new user mailbox in Exchange, they also create a corresponding Active Directory user at the same time. Now, there are multiple methods to create user mailboxes in Exchange.

In this article, we will discuss the methods to create a new user mailbox in Exchange. But, there are some points that you need to know before creating user mailboxes in Exchange.

Things to know before creating a user mailbox in Exchange Server

• You need assigned permissions from administrator to perform this procedure. You can check the Recipient Provisioning Permissions to know what permissions you need.
• The overall time to complete this procedure will be between 2 to 5 minutes.

Manual methods to create a new user mailbox

There are generally two ways to create user mailboxes in Exchange – using EAC and Exchange Management Shell. Let’s have a look at both these methods:

Method 1: Using Exchange Admin Console (EAC)

To create a new user mailbox, follow the below steps:

1. In the EAC, go to Recipients and select Mailboxes.
2. You’ll see a (+) sign, click it and select User mailbox.
   
3. The New user mailbox page will appear on the screen. Configure the settings on this page, such as Alias, New User, First name, Initials, Last Name, Display name, Name, Organizational Unit, and User login name.
   Note: The options marked with (*) are required to be filled.
4. Enter the New Password and confirm this password by entering again. Make sure the password length complies with the organization’s standards and requirements.
5. Check the box “Require password change on next login” to force users to change the password at the first sign in.
6. Click the Save button to create user mailbox and the Active Directory account associated with it. You can configure the following settings for user mailbox by clicking More options.
   • Mailbox database: click Browse to select the mailbox database that holds the mailbox.
   • Create an on-premises archive mailbox for the user
   • Address book policy: it defines an address list for the user

   After configuring the user mailbox settings, you can click Save. The user mailbox has been created successfully.

Method 2: Using Exchange Management Shell

Exchange Management Shell is another viable option to create user mailboxes in Exchange Server. It involves using various commands to create a new user mailbox.

Use the below syntax to create a user mailbox with Exchange Management Shell.

The parameters required to create a new user mailbox with the Exchange Management Shell are as follows:

• Name: (Himanshu), the same name will also be added to the display name, as we are not using DisplayName parameter.
• UserPrincipalName: the active directory account name will be as follows himanshug@contoso.com.
• Password: Pa$$word4

Apart from these, there are some optional parameters as well.

• FirstName: Himanshu
• LastName: Goyal
• The alias value will be himanshug as we aren’t using the Alias parameter.

These are the easiest methods to create a new user mailbox in the Exchange environment. After creating the new user mailbox, you can verify whether it’s created or not by going to EAC or EMS.
