I use an internet service provider (Cox Communications) for my email and the Windows 8 Windows Live Mail client (just upgraded from Windows XP and Outlook Express).   I have many duplicates in Contacts, spent hours deleting and when I logged back in, they had all returned.  I don't use Hotmail nor do I want to.  I actually keep my 'good' list of contacts in gmail as that seems to be the only thing I can figure out and which seems to work.   But I'd like to be able to delete the 5000 contacts in the Windows Live Mail Contact folder and start over.  Any solution to this?
This is happening on both my MacBook Pro and my iMac.  I have been to the Apple store 3 times in the last three weeks to try to resolve.  I have called Comcast, the internet service provider.  They claim it is not them. My family uses PCs and are not having any problems.  Any suggestions?

can you please help me
Added an iPhone with email and now MacBook Pro Outlook will not send/receive. Error message: "outlook doesn't support any of the available authentication methods".  Bellsouth is the internet service provider.  Neither they nor Verizon could help.  Next steps?  All worked fine until the phone was added. Another person who has PC added an iPad with email with no issues.  Same family and week.
