One of my users who is using a MAC runs Outlook 2011 (fully updated) and when he creates a new email address it is not appearing as a recent address. I know within a Windows install of Outlook there is the .NK2 file that is created for each profile and sometimes you need to recreate this file. Would this be similar in 2011 for MAC users? If so what file is created and if copying the contents of the file then deleting it so it creates a new file when starting Outlook would this solve the issue? 

Thoughts as always appreciated.
