I wonder the different maibox name. Instead of deleting the content, you can also copy the search result to another mailbox(-TargetMailbox -TargetFolder) to check the result first.

Hi shrigiriraj, Any updates?Frank Wang TechNet Community Support

I change the name of the user and domain name for my company policy.

Hi shrigiriraj, Yes, I understand. I just want to make sure Smith & Mona are same user object. How about the cmdlet now? Does it work?Frank Wang TechNet Community Support
