I think I know why but can't do any thing about it

Originally the live mail server was set to periodically go out and check my ISP's pop mail server and deliver them to live mail server so that on my laptop  I could send and receive mail from my ISP when not on my home network. (some mail would be late and some mail I would not receive because it was read and deleted at home before the next microsoft server read cycle)

Subsequently my ISP allowed a set forward command and also to leave mail on its server.  Now I am getting most mail twice,........and I cant undo the original set up. There seems to be nothing I can find that allows these settings to be reversed (or even set up for the first time)

Any help would be appreciated
