I have a user who is having an outlook mailbox password issue.

He has two machines at work ,he is running windows 7 with office 2010 and a mac-book with Mountain lion and office 2011.

His password expired so i when into AD and reset his password . Neither machine would accept his new credentials for Outlook, for his windows machine I followed this guide :

http://www.howtogeek.com/howto/windows-vista/fix-for-outlook-2007-constantly-asking-for-password-on-vista/

i renamed his %userprofile%\AppData\Roaming\Microsoft\Protect and his windows machine is no longer asking him for his password .

I'm not familiar with mac enough to pinpoint how to trouble shoot this same issue .

Does mac-have a similar workaround as in this guide? If not does anyone know where i can start ?
