0x800CCC78 452 4.4.5 Unable to send mail

[Hutchie]

Hi

I am using Outlook 2003 and Windows XP

Myself and another user on our network are getting the following messge when
trying to send emails.

Sending reported error (0x800CCC78) : 'Unable to send the message. Please
verify the email address in your account properties. The server responded 452
4.4.5 Insufficient disk space, try again later.'

There are 3 other people (and 17 users in total) currently active on the
network and they are having no problems sending and recieving mail.

There is no problem with the email addresses we are sending to, I have
changed the account settings so that the STMP server requires
authentification, I have deleted the messages from the inbox and tried to
resend, restarted Outlook and searched for information on how to resolve this
matter but much of the information is with regards to Outlook express.

I would greatly appreciate any help on this matter, and look forward to
hearing from you.

Thanks

An update is that everyone on the network seems to have the same problem. We
have a groupware system that allows us to see emails via a webmail type
service - this is showing no messages.

Is this likely to be a problem with our mail provider? Or ISP?

Thanks

It seems it was a problem with either our ISP or mail server provider as it
is working correctly again
