Spam Emails stuck in submissions queue

While checking message queue, I have noticed that Spam email stuck in the mail submission queue. Hence genuine emails getting delay to delivered.I found many email stuck in retry state and Last error state that as below :400 4.4.7 The server responded with: 550 5.6.0 M2MCVT.StorageError; storage error in content conversion. The failure was replaced by a retry response because the message was marked for retry if rejected.

Resolution :-

• Open Power shell as administrator.
• Run the below command.
• Get-Message -Filter {FromAddress -eq "<>"} -Server MYSERVERNAME | Remove-Message
• Issue resolved. Cheers!!!!
