In summary I deleted Yahoo Sync (I dont need it and don't care to have it running), however now my Addressbook and Calendar are negatively impacted.

Addressbook shows ZERO records, but all the meta data is there.

Calendar: I can not send invites as this must be dependent on the addressbook!!

So what I did not know was how embedded this Yahoo Sync is in the Apple applications. Had I known I would have obviously left it there.

I have tried to reinstall the addressbook app and done all the config file deletes etc.

Perhaps I have to rebuild from scratch! Perhaps a Lion OS upgrade will fix??

Any help on this issue would be greatly appreciated.


I'm running OSX 10.6.8 - all software is up to date.
