550 unknown user email message

[Yachtmaster]

I am getting the bounce message below when sending to a particular user with
a valid email address. The user name has been replaced with xxxxx.

This is both typing in the address or replying to an email. Other emails to
users on the same domain are working fine – any suggestions?

Does it work if you send to that person from your web based mail account?
If not, it's not an Outlook issue.

Sends from webmail OK, and I think it is an outlook issue but do not know
were to look.

This is clearly the mail router at cumberlandlodge.ac.uk telling you that
mailbox xxxxxxxx doesn't exist. I notice that the first set of Xs contains
six and the second set contains eight. Did you match the number of
characters exactly when you replaced the originals, or did you just type a
few Xs and were inconsistent in how many you typed?

I can successfully send to the email address from my webmail account for the
same email account in outlook. The xxxxx's were random to block the name and
not significant. Looking for an outlook solution. Everything else works fine
including other mail addresses at the domain.

Did you *copy* and paste the e-mail address from Outlook to the To
field in your webmail account when composing a new e-mail, or did YOU
type it in when testing with the webmail interface? Sometimes a
user's eye see what they expect to see and you have a typo that
doesn't pop out at you. Could be, for example, that you have leading
or trailing spaces in the e-mail address, or an embedded non-printable
character (so have you tried deleting and reentering the e-mail
address in Outlook?).

Also, what makes you think "cumberlandlodge.ac.uk" is a valid domain?
I tried "nslookup cumberlandlodge.ac.uk" and got no IP address listed
for that IP name. I also tried using www.dnsstuff.com to do a reverse
lookup and it reported there is no A record (IP address) for that
domain name. "cumberlandlodge.ac.uk" is a registered domain but being
registered doesn't mean it is an active domain. The registration says
that domain uses mail hosts at dns.mailbox.co.uk. You sure you have
the right domain? Maybe it is supposed to be cumberlandlodge.co.uk
since that one is defined

I wouldn't mind having my next conference there...

Maybe dnsstuff wasn't able to find it, but I think I can rely on GPS to get
there.

Can you successfully email to another person there? What if you send a
single email to them and put both addresses in the To: line?

Version of Outlook?
Type of mail account?
Are you a home or corporate Outlook user?

Hmm, so apparently they haven't bothered to designate a default host
('www') to their domain. I then used dnsstuff.com to do an MX record
lookup from "cumberlandlodge.ac.uk" and some mail hosts were listed
for them (but under a completely different domain). Yet I can do
"nslookup intel.com" and get back an IP address but not for this
domain.

Their Contact -> Staff Directory lists some e-mail address so maybe
the OP could check there if he is using the correct one. Of course,
since someone had to add them to that web page, it is possible the
username is incorrect. Under the "About Us" page, there is a general
e-mail address of (e-mail address removed) where the OP might
be able to start an inquiry regarding the correct e-mail address of
whomever he is trying to contact there.

The email address is valid and I can send emails via webmail. The person
receives emails happily from everyone else they are in contact with. I have
been though outlook and checked things like the Junk mail serttings but
cannot find a problem. I have tried to reply to the address and type in the
complete address and neither work.
