Outlook - Users get logon window multiple times during day

Some users get prompted to logon to Outlook while already logged on.  It happens multiple times through out the day.  When prompted to logon, Outlook indicates it is still connected to Exchange.  I happens to users who connect over our VPN and users who are on the same network as the CAS server. There are not any abnormal log entries on the CAS server, EV Server or the workstations involved.  Every time they are prompted to logon the entry on the CAS server is
"POST /Autodiscover/Autodiscover.xml - 443 domain\user (Workstation IP address)Microsoft+Office/14.0+Windows+NT+6.1;+Microsoft+Outlook+14.0.6129;+Pro) 200 0 0 15". There no any difference in the log entries for users having the problem and those who do not.   It can also randomly start and stop.  All servers are virtual.

Environment:
   Exchange 2010 - SP3 (it was happening prior to SP3) - Server 2008 R2
   Enterprise Vault 9.0.3 - Server 2003
   Outlook 2010 - connect using RPC over HTTP

We had 2 users with the problem.  The first was resolved by deleting the password in the credentials vault.  The second was resolved by deleting all file in any Outlook folder in the users profile. The second user did not have any saved passwords in the vault.
