Microsoft Windows Live team announced that rolling out Hotmail Wave 4 is picking up the pace. "And, by, we have over 100 million customers using the new Hotmail, and we're upgrading even more users as we speak. We expect to upgrade nearly all of our customers within the next week."
"Once the rollout of the new Hotmail is complete, we'll start preparing for the release of Exchange ActiveSync for Hotmail, which will allow you to sync your email, calendar, and contacts with your mobile phone. That release will happen later this summer – keep watching this blog for details," stated Microsoft.
