@NetworkNerd said in Outlook Slow to Open, Interesting tracert to Hosted E-mail Provider:
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.
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.
