One of the critical tasks every admin should know is how to back up and restore mailboxes using PowerShell. Here’s a streamlined approach to ensure your data is safe and easily recoverable.

Backing Up Mailboxes

Connect to Exchange Online: Use the following command to connect to your Exchange Online PowerShell session:

Connect-ExchangeOnline -UserPrincipalName [email protected]        

Export Mailbox Data: Utilize the?New-MailboxExportRequest?cmdlet to export the mailbox data to a PST file:

New-MailboxExportRequest -Mailbox [email protected] -FilePath \\YourFileShare\Backup\user_backup.pst        

Monitor the Export Request: Check the status of your export request with:

Get-MailboxExportRequest | Get-MailboxExportRequestStatistics        

Restoring Mailboxes

Import Mailbox Data: To restore a mailbox from a PST file, use the?New-MailboxImportRequest?cmdlet:

New-MailboxImportRequest -Mailbox [email protected] -FilePath \\YourFileShare\Backup\user_backup.pst        

Monitor the Import Request: Similar to exports, you can monitor the import request with:

1Get-MailboxImportRequest | Get-MailboxImportRequestStatistics
