Troubleshoot Outlook connection issues

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?

Have you checked for any DNS conflicts?  Or flushing the dns on the local machine, perhaps an old entry for the exchange box is listed and is causing conflicts.

I would definitely start by testing on a new switch.

The problem seems to have been resolved after we changed our WAN provider.
