Delivery has failed to these recipients or distribution lists:
There's a problem with the recipient's mailbox. Microsoft Exchange will not try to redeliver this message for you. Please try resending this message, or provide the following diagnostic text to your system administrator.
I have no issues with sending the same information directly to this person. There is plenty of storage so that is not the issue. I see similar complaints on the internet about this. I have no issues with 2007. This is only with 2010.
