I currently have about 5-6 different e-mail accounts for different servers, and the annoying thing is that all of the e-mails go into one single inbox in Outlook Express (Windows Mail). I can't seem to find an option for directing e-mails to a named folder - how can this be done with Outlook?

Well which is it, Outlook or Windows Mail?

In Windows Mail, click tools > Message Rules > Mail and then you can sort by whatever you want, including the destination email address.

Thanks - Was hard to spot because the OS is in Korean.

That'll teach you to trust microsoft to make something work in another language
