Don't know if anyone can help, but here goes.  We are running an
Exchange 5.5 server and I am running Outlook 2003.  Email that is sent
to me internally is very slow to arrive (up to 30-45 seconds),
including email I send to myself.  Nobody else in my immediate vicinity
is having the same issue, their email arrival is instant.  We have
reviewed Outlook settings and they are identical.  One strange thing is
this:  If I send myself an email, don't do anything, it will come in
within 30-45 seconds.  However, if I send myself an email, then
immediately send another email both of them will come in instantly.
Anyone ever seen this behaviour before?

Thanks,

Brian
