New-Mailbox -Name "Jane Smith" -UserPrincipalName jsmith@example.com -FirstName "Jane" -LastName "Smith" -Location "Office"
This command creates a new mailbox for the user Jane Smith.
- Creating a Shared Mailbox:
New-Mailbox -Name "Support" -DisplayName "Support Team" -Shared

Common Errors and Troubleshooting Tips
Common New-Mailbox Errors
As with any command, you may encounter errors while using New-Mailbox. Some frequent issues include:
- The user already exists: This error suggests that the specified User Principal Name or another identifier already exists in the directory. You may need to verify whether the user already has an associated mailbox or consider a different identifying name.
Troubleshooting New-Mailbox Issues
To troubleshoot potential problems effectively, consider these best practices:
-
Check Permissions: Ensure that the account you are using has sufficient privileges to create mailboxes.
-
Verify Existing Users and Mailboxes: Use the `Get-Mailbox` cmdlet to review existing mailboxes and avoid conflicts.
-
Use Verbose Logging for Information: The `-Verbose` switch can provide additional details about the command's execution, helping identify issues:

Customizing Mailbox Settings
Adding Mailbox Features
Once a mailbox is created, you can customize various features and settings to enhance functionality. Common configurations include setting mailbox size limits and managing mailbox permissions.
For example, to modify mailbox quotas, use:
Set-Mailbox -Identity "Jane Smith" -ProhibitSendQuota 10GB -ProhibitSendReceiveQuota 11GB
This command will set restrictions on how much mail Jane Smith can send and receive.
Setting Up Forwarding and Email Aliases

Set-Mailbox -Identity "Jane Smith" -ForwardingAddress "otheruser@example.com"
