Speed of data transfer over WAN - synchronization

Hi
I have a WAN link to one of our branches, it runs over a 128k diginet line(Windows 2000 Domain). The users use it for E-Mail and data transfer. The transfering of data is very slow, is there any way to speed up this transfer. I was thinking of some way to do directory synchronization, not sure if this is a solution to the problem.

Is it the Outlook/Exchange traffic that uses all the bandwidth..

Any possible solutions ......

When you say that the transferring of data is "very slow", what EXACTLY do you mean?  In my opinion, 128K b/s is very slow to start with and you may be operating at full speed but simply overwhelming the data line.  So while the link speed is fully 128K, you are trying to push too much data down a small pipe.

Mail traffic is usually short bursts of data. If your users are copying files over the link, like jhance mentions, it will fill the pipe. There really isn't much you can do to get around that problem. We ran a 128k line for many years, and quickly realized that it was only enough bandwidth for sync'ing domain info, and mail. Large attachments still caused grief, but like I said, it was for short bursts.
We ended up moving to a site to site vpn connetion via our high speed internet feeds (~4.5mb). Much nicer, and acceptable for everyday file transfers, and no 128k line cost. That alone paid for the VPN enabled firewall devices.
