For some reason a number of my yahoo.com email is not on my Outlook for Mac, but is on the yahoo server, my iPad and iPhone.

Is there a way to "refresh" the email data back down to Outlook without deleting the account from Outlook?

If not, what are the steps to delete the yahoo account from Outlook and then add the account back on with out accidentally deleting email from the yahoo sever?

As always - Many thanks!
