Hello:
Windows Live Mail 2011/Win 7

Is there a way to create/set to remove/delete e-mails automatically after a number of days, ... i.e. 7 days' accumulated e-mails? Because, there are three different PCs/Win 7 on the PC table and I'm unable to keep up with all e-mails coming to in-boxes of three different PCs. On reading those e-mails is I depend on only one PC/Win 7 while other two PCs is sitting for 'back-up' purpose.

Thanks for your help in advance.
