I'm looking for a good way to consolidate my many email/messenger contacts through my different accounts and services. I'd like to have all my contacts in one place, or have them sync between all my different services so they are the same everywhere. If possible, it should support Live Mail/Messenger, Google Contacts, and mobile syncing.
Windows Live Mail is great for accessing all your mail accounts, but the contacts viewer only works for contacts affiliated with that Live account. I could go for the contacts folder built into Vista and above, but Live messenger doesn't access that so I would have a separate set of contacts for my IM account.
Is there software, or an online service, that can do this? If this is asking to much, is there a proper solution to Live/Google Contacts bidirectional sync?
