I have multiple google email accounts (not just GMail, but ones set up with Google to handle email for other domains). All of these accounts sync with my Windows Phone, and I was wondering if its possible to extend the sync partnership to Outlook 2010 (maintain read/unread status, deleted, folders, etc). I have no interest in spending money on these accounts, so I was wondering if its possible to do it for free or with specific tools?
As your phone is making a connection to each accounts... so must your desktop client (outlook) Your phone isn't tying them together... it simply displays them on one screen. Yes, you can setup as many accounts in outlook as your phone does (probably more). Anything your phone can connect to... more than likely... outlook can as well.
Also, As long as you're not using POP, you can also keep the read/unread status in-sync.
