Follow the instruction below:
1. First, AttachRMEExchangeMailbox cmdlet connects to the User's mailbox:
- $target = AttachRMEExchangeMailbox "Name of the Mailbox"
2. Then Attach-RMEExchangeDB cmdlet connects to the offline Exchange Server database (.EDB), and then pipes the database object to the Get-RMEMailbox cmdlet. The Get-RMEMailbox cmdlet gets the User's mailbox object, and pipes it to the RestoreRMEMailbox cmdlet. Then finally, the Restore-RMEMailbox cmdlet restores the entire User's offline mailbox to the root of the target online mailbox.
- Attach-RMEExchangeDB "Exact Name & Location of the Offline Exchange Database " | Get-RMEMailbox "Name of the Mailbox" | Restore-RMEMailbox TargetFolder $target
