All,

I'm attempting to make this work so that my Lumia 920 will be useful in syncing with my Yahoo calendar.  I've tried variations.  When I subscribe Outlook to my Yahoo calendar most (all but one) of my dates displayed without a "title" on Outlook.  I've tried to share my Yahoo calendar with Outlook.com, but Yahoo doesn't like the ICS web address that Outlook supplies.

I really don't want to have to use Outlook.com exclusively as I've been using Yahoo for years.  It's part of my AT&T landline and DSL package.  The Lumia 920 Amber/GDR2 update doesn't really seem to openly support true CalDav/CardDav.  The only synchronization seems to be with Google and Outlook.com.  I'm less concerned about the email feature.  I just would prefer to have this work as it should.  AT&T, Microsoft and Yahoo should play nice together and make this work.

Any suggestions?
