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
