Not receiving messages

[Terry]

I’m using Outlook 07, my incoming mail is maintained by a hosting company,
and my outgoing mail is controlled by my cable company which I am forced to
use.

Many times when I send mail it can take hours to reach its destination,
sometimes never at all. The same for mail sent to me. Sometimes there are
attachments up to 4Mb; however often the attachments go through other times
nothing.

I have a distribution group of 15 people, using outlook I put the
distribution group in the bcc address, about half the people get the message.
Yet sending to the group individually all receive the message.

When I called the cable company, they pointed the finger at my incoming mail
provider and Outlook. When I called my incoming mail provider, yep, the same
finger pointing.

Is there any way to trace this problem?

Also does Outlook stop or block large attachments incoming or out going?

Many thanks
