Restore deleted user data to new mailbox




Connect PowerShell to Exchange Online using below command:
  • $LiveCred = Get-Credential
  • $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic –AllowRedirection
  • Import-PSSession $Session
Then checked the old user in Soft Delete
  • Get-Mailbox –SoftDeletedMailbox  //Check the deleted user details
  • Get-mailbox –SoftDeletedMailbox –Identity “Name of the mailbox” | fl *guid*
  • Copy the GUID (not Exchange GUID) in a notepad (1)
  • Get-mailbox –Identity “Email address of the new user” | fl *guid*
  • Copy the GUID (2)
Following command will copy the old mailbox’s email to the new mailbox.
  • New-MailboxRestoreRequest -SourceMailbox "GUID (1)" -TargetMailbox "GUID (2)" -TargetRootFolder "Old Mailbox" –AllowLegacyDNMismatch
Since user had Archive enabled we restored the archive mailbox seperately
We ran the below commands to get the ArchiveGuid
Get-Mailbox -Identity user@domain.com -SoftDeletedMailbox |fl " ArchiveGuid"
Get-Mailbox -Identity user@domain.com |fl "ArchiveGuid"
  • New-MailboxRestoreRequest -SourceMailbox "GUID (1)" -TargetMailbox "GUID (2)" -TargetRootFolder "Old Mailbox" –AllowLegacyDNMismatch

    Microsoft documentation states to use ExchangeGuid. You state to use Guid. Have you done this with both or just Guid?
