Outlook Slow to Open, Interesting tracert to Hosted E-mail Provider



  • We have a hosted Exchange server through Sherweb. At our Dallas office, we have around 35 employees and a 20/20 fiber connection (runs data and voice, QoS handled by ISP since hosted VOIP is through them).

    I came from an environment that had an in-house Exchange server, so opening Outlook was rarely ever slow. But what I have noticed here is that for most people here in the Dallas office, it takes an extreme amount of time to open Outlook and to get "connected to Microsoft Exchange." Once you're "connected," things seem to work fine. But, there have been times when people will lose connectivity to the hosted Exchange server.

    I'm not aware in any case that the choking point has been bandwidth. Sherweb is telling us all is well on their end. Ping times from us to the hosted Exchange server are normally less than 50ms. But if you do a tracert, that is an entirely different story:

    Check out the latency on that 4th hop. At that point traffic goes across Level 3's network (supposedly still a server in Dallas). We brought this up with our provider (LightSpar), and they are telling us that despite the latency showing to be high on the tracert, it is not delaying the exchange of information between us and our hosted Exchange server. That kind of hop latency is not present if you do a tracert from another location to our hosted Exchange server, so I'm not sure what is happening here.

    We're moving away from hosted Exchange to O365 in the next couple of months, but I wanted to try and get this cleared up either way if is indeed a problem with our ISP. In general, no one here has had issues connecting to the internet or calling it slow. The "slow" is always e-mail.

    What am I missing here?



  • Traceroute is not showing what you think it is showing. Nor can it. A ping is a ping, traceroute cant show that it is slower.

    It can't be, you prove that it is not having any affect from your ping and traceroute. Your latency is under 50ms, so its own response time is irrelevant.
