I recently purchased an iPhone 4S and have a Yahoo! account where I send/receive emails through Microsoft Outlook on my home PC. I would like to set up my phone so that I can use my Outlook email exclusively, both at home and when I travel, as it provides many more options than Yahoo mail. My Yahoo mail account synchs with my iPhone, but when I use Outlook (on my PC), I have to duplicate my efforts by deleting emails or moving them to folders, which I have already done in Yahoo. Is there a work around for this, or do I need a corporate account/an IT dept in order to set up an Outlook Web access for this to work?
