Outlook 2003 slow to send and receive
 

My Outlook 2003 client does not send and receive immediately. If, for
instance an e-mail is sent to me, it takes at least 10 seconds to get
to my inbox, if I send an e-mail it takes roughly the same amount of
time to send (internal and external).

Notes:
It is connected to Exchange 2003
It is not running in cached mode
All my Outlook 2002 clients send and receive immediately
OWA sends and receives immediately
Under Tools, Options, Mail Setup, Send/Receive - Group Name is set to
"All accounts" and Send/Receive When is set to "Online and Offline"
Both "Include this group in send/receive (F9)" are checked.

Can anybody offer me any suggestions as to why this is happening.

Thanks in advance
