sending emails returned with error 5545.7.1 address rejected

[Russell]

When I try to send an email it is returned with error 5545.7.1 recipient
address rejected access denied.
This seems to happen for a while, then it is ok aqnd then starts happening
again.
Any help would be much appreciated.

I would have one of those messages handy and call the email provider that
is returning the message. If it sends, then Outlook is done with it and
it is something on the Internet that is now at fault.

Error 554 5.7.1, actually; this is the remote mail server telling your mail
server that there is a problem. Since you did not grace us with the verbose
component of the error message, we can only guess at the cause. However,
your comment that the email will sometimes not be rejected suggests that the
recipient mailbox may be full. Next time you get this message, call your
correspondent and tell them to clean out their Inbox.
