Unable to restore the SoftDeleted mailbox in O365

Question

Hi all,

I am creating a Windows Form with below function to restore the O365 soft deleted mailbox to a new created shared mailbox. Here's the function details:

function Restore {
    $ResignedEmail = $ResignedInput.Text
    $ResignedStillExist = Get-Mailbox -Filter {UserPrincipalName -eq $ResignedEmail} -ErrorAction SilentlyContinue
          if($ResignedStillExist -eq $null){
                $ResultOutput.Text = echo "Mailbox $ResignedEmail is not exist, can continue.`r`n"
		$ResignedGUID = Get-Mailbox -SoftDeletedMailbox -Identity $ResignedEmail | select Guid
		$ResignedMailboxName = Get-Mailbox -SoftDeletedMailbox -Identity $ResignedEmail | select DisplayName 
		$ResingedMailboxAlias = Get-Mailbox -SoftDeletedMailbox -Identity $ResignedEmail | select Alias
		$NewMailboxAlias = ($ResingedMailboxAlias).Alias -replace '\s','' #Remove the space in Alias
		$NewMailboxName = ($ResignedMailboxName).DisplayName + "_Restored"
		$NewMailboxEmail = $ResignedInput.Text
			New-Mailbox -Name $NewMailboxName -Alias $NewMailboxAlias -Shared -PrimarySmtpAddress $NewMailboxEmail
		$NewMailboxGUID = Get-Mailbox -Identity $NewMailboxName | select GUID
			if ($NewMailboxGUID -eq $null) {
				$ResultOutput.Text = echo "Shared mailbox cannot be created"
			        }
			else {
				New-MailboxRestoreRequest -SourceMailbox $ResignedGUID -TargetMailbox $NewMailboxGUID -AllowLegacyDNMismatch
				$ResultOutput.Text += echo "Resigned Staff mailbox has been restored."
				$ForwardToEmail = $ForwardToInput.Text
				Set-Mailbox $NewMailboxName -ForwardingAddress $ForwardToEmail -DeliverToMailboxAndForward $True
				$ResultOutput.Text += echo "Email forwarding has been done."
			        }	
			}
	else {
	$ResultOutput.Text = echo "$ResignedEmail is still exist, no actions taken. Please wait for the mailbox been removed.`r`n"	
	}
}

However, once I run it and the below errors occurs:

Cannot process argument transformation on parameter 'TargetMailbox'. Cannot convert value
"@{MailboxGuid=c0xxxx-ae13-46fe-86dd-5c067xxxxxf4}" to type
"Microsoft.Exchange.Configuration.Tasks.MailboxLocationIdParameter". Error: "Cannot convert hashtable to an object of
the following type: Microsoft.Exchange.Configuration.Tasks.MailboxLocationIdParameter. Hashtable-to-Object conversion

    + CategoryInfo          : InvalidData: (:) [New-MailboxRestoreRequest], ParameterBindin...mationException

Cannot process argument transformation on parameter 'SourceMailbox'. Cannot convert the "3f7e91a-2bad-0433-fd04-e2ae8e83de24" value of type "System.Guid" to type "Microsoft.Exchange.Configuration.Tasks.MailboxLocationIdParameter".

     + FullyQulifiedErrorId  : ParameterArgumentTransformationError,New-MailboxRestoreRequest
     + PSComputerName   : outlook.office365.com

I've tried to change the below script

$NewMailboxGUID = Get-Mailbox -Identity $NewMailboxName | select GUID

to be:

$NewMailboxGUID = Get-Mailbox -Identity $NewMailboxName | select ExchangeGUID

or to be:

$NewMailboxGUID = Get-MailboxLocation -Identity $NewMailboxName | select MailboxGuid

But all get the similar errors back.

Do you have any idea how can I fix this to let the function works? Thanks a lot!

Hi Lavenie,

According to the code you provided, your issue is more related about PowerShell. And this forum is discussing and asking questions about the Windows Form and ClickOnce. I will move this thread to corresponding forum: Windows PowerShell.

Thank you for your understanding.

Kyle

Hi,

Thanks for your question.

You can try this.

$NewMailboxGUID = (Get-MailboxLocation -Identity $NewMailboxName).GUID

Best regards,

Just do it.

Hi Lee,

Thanks for your help!!

however, after I changed the script as above, the Form displayed "Shared mailbox cannot be created", which means it triggered $NewMailboxGuid is null.

$NewMailboxGUID = (Get-MailboxLocation -Identity $NewMailboxName).GUID
			if ($NewMailboxGUID -eq $null) {
				$ResultOutput.Text = echo "Shared mailbox cannot be created"
			        }

And if I changed as below,

$NewMailboxGUID = (Get-MailboxLocation -Identity $NewMailboxName).MailboxGUID
	if ($NewMailboxGUID -eq $null) {
	            $ResultOutput.Text = echo "Shared mailbox cannot be created" }

The error becomes as this:

Cannot process argument transformation on parameter 'SourceMailbox'. Cannot convert value
"@{Guid=0435dc-7ss3-4exx-bs3a-457c0sssss3}" to type
"Microsoft.Exchange.Configuration.Tasks.MailboxLocationIdParameter". Error: "Cannot convert hashtable to an object of
the following type: Microsoft.Exchange.Configuration.Tasks.MailboxLocationIdParameter. Hashtable-to-Object conversion
is not supported in restricted language mode or a Data section."
    + CategoryInfo          : InvalidData: (:) [New-MailboxRestoreRequest], ParameterBindin...mationException
    + FullyQualifiedErrorId : ParameterArgumentTransformationError,New-MailboxRestoreRequest
    + PSComputerName        : outlook.office365.com

Thank you!!

Hi Lavenie,

When you run (Get-MailboxLocation -Identity $NewMailboxName).GUID, whether you can any output.

Also, you need to check $NewMailboxName. Try to just run $NewMailboxName, to check the output.

$ResignedGUID = (Get-Mailbox -SoftDeletedMailbox -Identity $ResignedEmail).GUID $ResignedMailboxName = (Get-Mailbox -SoftDeletedMailbox -Identity $ResignedEmail).DisplayName $ResingedMailboxAlias = (Get-Mailbox -SoftDeletedMailbox -Identity $ResignedEmail).Alias

If you use select, you will get an aduser object with GUID/displayname property. If you use the code as I posted, you will save a string object with GUID value to the variable.

Best regards,

Lee

Hi Lee,

Thank you again!

I've tried few times these days, but I also got the same error:

Cannot process argument transformation on parameter 'SourceMailbox'. Cannot convert the
"bb793a20-e334-48c9-b9ec-bbcd1f57677c" value of type "System.Guid" to type
"Microsoft.Exchange.Configuration.Tasks.MailboxLocationIdParameter".
    + CategoryInfo          : InvalidData: (:) [New-MailboxRestoreRequest], ParameterBindin...mationException
    + FullyQualifiedErrorId : ParameterArgumentTransformationError,New-MailboxRestoreRequest
    + PSComputerName        : outlook.office365.com

Here's my revised script:

function Restore {
	$ResignedEmail = $ResignedInput.Text
    $ResignedStillExist = Get-Mailbox -Filter {UserPrincipalName -eq $ResignedEmail} -ErrorAction SilentlyContinue
    if($ResignedStillExist -eq $null){
        $ResultOutput.Text = echo "Mailbox $ResignedEmail is not exist, can continue.`r`n"
		$ResignedGUID = (Get-Mailbox -SoftDeletedMailbox -Identity $ResignedEmail).ExchangeGUID
		$ResignedMailboxName = (Get-Mailbox -SoftDeletedMailbox -Identity $ResignedEmail).DisplayName 
		$ResingedMailboxAlias = (Get-Mailbox -SoftDeletedMailbox -Identity $ResignedEmail).Alias
		$NewMailboxAlias = $ResingedMailboxAlias -replace '\s','' #Remove the space in Alias
		$NewMailboxName = $ResignedMailboxName + "_Restored"
		$NewMailboxEmail = $ResignedInput.Text
		New-Mailbox -Name $NewMailboxName -Alias $NewMailboxAlias -Shared -PrimarySmtpAddress $NewMailboxEmail
		$NewMailboxGUID = (Get-MailboxLocation -Identity $NewMailboxName).MailboxGUID
			$ResultOutput.Text = echo "New Mailbox $NewMailboxEmail created.`r`nResigned Mailbox GUID is: $ResignedGUID. `r`nNew Mailbox GUID is: $NewMailboxGUID`r`nAlias is: $NewMailboxAlias`r`nName is: $NewMailboxName`r`nEmail is: $NewMailboxEmail. `r`n"
					if ($NewMailboxGUID -eq $null) {
							$ResultOutput.Text = echo "Shared mailbox cannot be created"
							}
					else {
							New-MailboxRestoreRequest -SourceMailbox $ResignedGUID -TargetMailbox $NewMailboxGUID -AllowLegacyDNMismatch
								$ResultOutput.Text += echo "Resigned Staff mailbox has been restored.`r`n"
							$ForwardToEmail = $ForwardToInput.Text
							Set-Mailbox $NewMailboxName -ForwardingAddress $ForwardToEmail -DeliverToMailboxAndForward $True
								$ResultOutput.Text += echo "Email forwarding has been done."
						}	
						}
	else {
	$ResultOutput.Text = echo "$ResignedEmail is still exist, no actions taken. Please wait for the mailbox been removed.`r`n"	
	}

I've tried ExchangeGUID, GUID, and MailboxGUID, still same result.

$ResignedGUID = (Get-Mailbox -SoftDeletedMailbox -Identity $ResignedEmail).ExchangeGUID

$ResignedGUID = (Get-Mailbox -SoftDeletedMailbox -Identity $ResignedEmail).GUID
$NewMailboxGUID = (Get-MailboxLocation -Identity $NewMailboxName).MailboxGUID
$NewMailboxGUID = (Get-MailboxLocation -Identity $NewMailboxName).GUID

Do you still have any idea for the error? Thanks!!!
