I can't say I have ever seen this happen with Outlook to be honest?  
Usually when this happens it means the user has added their one account 
in Outlook more than once?  Which version do you see this happen in?

Dovecot can be made to do exclusive locks, or the default is to share 
the mailbox.  I don't recall the config option, but check a recent conf file

Now that's just silly talk.  Upgrade to a more recent version anyway

If you post your OS type then I'm sure someone will help with packages - 
otherwise compile from source
