What mailbox format is this user using for his/her folders?  If I 
remember correctly from many years ago I saw similar issues when one 
uses Outlook with the old "unix" folder format and the user's Outlook 
connection got the "kiss of death" due to another imap process getting 
access to the folder.  Outlook would sometimes in this case not 
automatically acquire a new IMAP connection, but instead "freeze up" and 
require a restart before it would get a new working connection.  This 
sounds kind of like what you are reporting.

If this is the issue, it could be resolved by moving this user to mbx or 
mix formatted folders.
