I am having problems with Outlook/Exchange connectivity.
Site 1 has 6 users using Outlook 2007 on XP. 1.5 MB T1
Site 2 is where my Exchange 2003 mail server is located. 3.0 MB T1s
Both sites are connected on MPLS network.
About a month ago, site 1 users began to experience abnormal amounts of Outlook disconnect/reconnect. They also report to have frequent problems opening attachments. No other apparent network problems. With one user, I have rebuilt their Outlook profile, tested cabling back to the switch, and moved user to a different switch port. Switch is a 3Com 2924 POE switch. It is not running the latest firmware, that is a project in the future. We have another older 3Com switch. I am not sure if all 6 users are on the same switch or on separate switches, I haven't verified this.
The behavior reportedly is worse for two particular users but all 6 users are experiencing issues.
I have 5 other sites that are not experiencing these issues, so it's isolated to site 1.
I believe it may be a carrier network issue. We are in the process of changing to a new carrier network which I hope will resolve the issue. This started about a month ago, so it hasn't always done this.
Any ideas on what to do to trace down the source of these issues?
