Latency Problems with Exchange 5.5 and O

By mgalaz ·
We have a mainsite when our Exchange Server 5.5 resides, and a sub-site (other city) where 20 clients connect to our main site via dedicated 56k connection. The mainsite has a T-1 connection.

Problem: About five weeks ago, the sub-site began to experience latency problems when accessing OutLook from their desktop. It take 3 minutes for the program to finally open up and then another 3 for the program to become functional. And try sending attachements. The created total failure at the sub-site. If they access the email serices via OutLook Web Access, very thing works great. When if they are using the desk top software, everything comes to a crawl.

My service provider for both the T-1 and the 56k monitored my lines to see if the problems were there. This investigation turned up nothing.

So where my latency problem? On my Server?

Latency Problems with Exchange 5.5 and O

The problem here is that of bandwith. Launching an application such as Outlook over a link this slow put a lot of overhead on throughput as well as impact on the server.

This is the much reason why Outlook Web Access might be an answer a it uses a thin client webmail technology whereby messages are read directly on the server without relying on a fat client to translate the messages.

Outlook as a client poles the Exchange server directly therefore requiring more than enough bandwidth to communicate especially when more users are connected remotely. Outlook Web Access on the other hand displays the messages via the browser with less overhead although with few limitations i.e. not being able to read personal folders (pst) etc.
