Hello,
We have a mixed setup with Exchange 2003 and Exchange 2010.
We are noticing a wierd issue where, when a meeting invite is forwarded by a Exchange 2010 users to a Exchange 2003 user, we are seeing that a NDR is received.
The NDR is below
-------------------------------------------------------------------
Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept e-mail from certain senders, or another restriction may be preventing delivery.
-- The NDR generating servers is the 2003 bridgehead server.
Also, turned up logging.
