here is the code I put :

```auto
$deletedGroup= Get-Mailbox -SoftDeletedMailbox -GroupMailbox -Filter {name -like "Test group 2"} 
$targetuser=get-mailbox -Identity Bills@carlotz.com
New-MailboxRestoreRequest -SourceMailbox $deletedGroup.DistinguishedName -TargetMailbox $targetuser.DistinguishedName -AllowLegacyDNMismatch -Verbose

```

\*\*my error says to provide a value for -SourceMailbox but I am providing one by putting the variable that I created there \*\*

Did you check the content of the variable you want to use? Try to use the subexpression operator.

Yeah, I just took the variables out and manually put in the target and source mailboxes.

```auto
New-MailboxRestoreRequest -SourceMailbox testgroup2@outlook.com -TargetMailbox testshared@outlook.com -AllowLegacyDNMismatch -Verbose

```
