It sometimes becomes necessary for Exchange administrators to export a disconnected Exchange mailbox to PST files to preserve it for future use.

Even after a mailbox is disconnected, it exists in the mailbox database. But no user is associated with it. And, you can use PowerShell cmdlets to export mailboxes to PST after connecting it to a user.

Export Disconnected Mailboxes to PST

The Exchange Database preserves disconnected mailboxes until the retention period is over. But, to export them to PST, you need an attached account. Users can easily create a test account, and later on, delete it. Follow the below steps to understand the process:

  1. Create a temporary user account by using the Active Directory Users.
  2. After creating the account, go to Exchange Management Console on your PC.
  3. Expand the Recipient configuration and click on Disconnected Mailbox.
  4. Find the specific mailbox that you want to recover. Right-click on the disconnected mailbox and click Connect and check the checkbox User Mailbox.
  5. Under the Existing User section, click Browse and choose the temporary user that you created recently.
  6. Enter a name for the mailbox and click Next.
  7. Now, click the Connect button to connect the mailboxes.

Once the disconnected mailbox is connected to the user, you can export it to PST with the help of Exchange Management Shell using ‘New-MailboxExportRequest’ cmdlet.

New-MailboxExportRequest -Mailbox -FilePath “location\name of pst”

After exporting the mailbox to PST, you can disconnect it and delete the temporary user account.
