office 365 email host, exchange smtp and FQDN issues.
Posted on 2014-02-18
quick question. I ran the exchange trouble shooting analyser as i have had a few problems after a third party upgraded some of their software which uses our outgoing SMTP.
Out setup is as follows. (not ideal and soon to be upgraded)
Our domais are hosted by BT in the uk who use office 365. We have a catch all for our domain which is connected via a pop3 connection to BT's office 365 outlook online.
I now seems to have a SMTP and FQDN that dont match ans have has a feq DNR's over the past few weeks.
Our DNS is servername.internaldomain.local
Our SMTP FQDN is webdomain.org.uk
When I lookup our MX records online the point to webdomain-org-uk.mail.eo.outlook.com
Can anyone point me in the correct direction?
