I have been having difficulties sending emails - quite often they sit
in my outbox and don't move to my sent box until I send them a second
time. I finally received an error message stating:

Incoming

An outlook express store file may be damaged Please use a utility such
as scan disk to verify and repair any damaged files.

Protocol smtp port 0 secure ssl no error number 0x800c0155

How can I fix this? Our IT person says I am storing too many emails!
