This is just a general question regarding Outlook and Exchange. I have no idea which subforum this should be in, so here it goes... I receive a Windows computer from work which hosts my @work.com e-mail address. On my Mac, I installed Office for Mac which obviously includes Outlook. Since then, whilst at home or in work, I usually favour sending e-mails from my Mac and it's all worked fine thus far. Though I'm getting worried that maybe I'm creating double the amount of data on the Exchange servers and maybe I should remove it from the Mac? Can anyone offer some insight on this issue? Am I doing something I shouldn't really be?
