Verify some information re the switch to Yahoo.

I use Outlook 2007 for downloading Xfinity email.  I have lots of emails saved in folders, plus several rss feeds. Am I correct that this stuff will not be affected by the switch to Yahoo?  The only email affected will be what is on the web.  Is this correct?

I know I can continue to use Outlook 2007 with Yahoo with the proper setup.  I just need confirmation that what I have saved on my desktop will not be affected by the move.  Just a nervous Nellie with 84 years.

Thanks.
