Any suggestions why my outlook keep on losing connection to exchange server 2003? I confirmed that I have network connection because I kept on pinging the server constantly and no request time out. It take a while to respond my outlook but if I have no problem if I am using the OWA. I tried upgrading my oulook fron 2000 to 2007 but no difference. It kept on poppinng "coonection to microsoft exchange has been lost" and "connection to microsoft exchnage has been restore". Any help would be appreciated.
