Exgange not working?
Posted on 2009-07-01
Having had our broadband service down for a couple of days, we thought it was all resolved when the service was restarted. However, we find that although we can browse the internet, and access all files on our local server, we canot send or receive e-mails. We are using POP3 connections, but I cannot see how to check what is going off.
Neither can we access our exchange server (2003SBS by the way) remotely.
Ho can I trap where the problem lies? The outlook clients connect to the mail boxes, but when we try to send, the message bounces back saying :-
Your message did not reach some or all of the intended recipients.
The following recipients could not be reached
There was a SMTP communication problem with the recipients email server
Please contact your system administrator
<domainname.co.uk #5.5.0 smtp;550
<firstname.lastname@example.org> no such user here>
This reports an SMTP error, but as we are using POP3 connections..............
Does anyone have any ideas? This is now urgent as we have been down for a couple of days now.
