Having some intermittent probs. With email's. Have windows 2008 sbs w/exchange 2007 and using outlook 2010. This only happens to 6-8 people...What happens is that an email being sent out usually is rejected or Delivery is delayed to these,6-8, recipients or distribution lists.  They fail with error code 550 x.x.x, usually a #550 5.7.1  or 4.4.7 QUEUE.Expired; message expired ##..seems to me to be a prob. At the receiving end, have ran tests at mxlookup and we are not on a black list .and have not seen any probs. Show up on our end...this happens to workstations using 2010 or 2003 and to several workstations, meaning if the email address fails on one it will fail on another.....how can I trace down if it is our prob. Or the receiver..see following examples...seems when email is sent it pretty much errors asap, doesn't look like it even tries to send and then error..error message comes back with in 10 sec's..maybe it tries...just don't know for sure....all other email's seem fine.....having prob. With 6-8 diff. address's.all the rest, which are several hundred outgoing daily are ok...Also can send to others within the same company but not to one of the people....??....thx

This account has been disabled or discontinued

It looks like the problem is with the accounts being sent to, not the originating accounts.
To confirm, can you send a test message from an account which has had no problems to the addresses which have not been working?  This will confirm if the problem is with the destination address.

Message rejected due to content restrictions

What was the email message?  It looks like the recipient didn't like something about the email being sent.  Maybe an attachment or size restriction?

Please check your dns settings, also the ptr of your exchange server ip. Disabled and content restrictions are settings of the recipient mailboxes.
