We are running Exchange Server 5.5, and clients are using Outlook 97+2000. At our remote offices, which connect via Frame Relay at port speeds of 64K-512K we have many complaints of slow downs. My question is this...When an email attachment is sent out to user at a remote site, and the user then opens that email, not the attachment does Outlook open a portion of the attachment in anticipation of the possibility the user is going to open it? We're wondering if this could be part of the slow down? Obviously if multiple users are opening attachments at a remote site and the attachment is fairly large it will slow down over the WAN link, but many times nothing is opened but a slow down still occurs?
Any insight is apppreciated!
