Fails in Outlook 2003, 2007,2013.
We are using exchange2010.
The following recipient(s) cannot be reached:'firstname.lastname@example.org' on 7/24/2013 12:01 PM
You do not have permission to send to this recipient. For assistance, contact your system administrator.<mail.domainxyz.com.au #5.7.1 smtp;550 5.7.1 ip>
Based on my experience, the error code 550 5.7.1 means that the sender does not have the permission to send messages to this recipient.
To troubleshoot this issue, I appreciate you to help me answering the following questions first:
- How many users are affected by this issue?
- Could we always reproduce this issue if we send emails to other mailboxes in the same domain?
- What kind of the Outlook profile do your users use? Exchange MAPI profile or POP3/SMTP and IMAP/SMTP?
Since the email could be delivered in OWA and iPhone, your Outlook client users might use different method and SMTP server to deliver the message. So we suggest you to check your mail flow from the Outlook client to the recipient, see if there is any incorrect permission setting blocked the message.
Here are some articles talking about the NDR and the error code in NDR messages, hope they could be useful:

Quesiton : Are they replying to old emails or the new emails.

Are the recipients Internal to the Domain or external to the domain ?
