Through the preview, users can sync SharePoint Online document libraries and OneDrive folders shared with others. There's also a new activity center for the OneDrive sync client that allows users to view sync and file activity at a glance that's in preview as of this week.
Microsoft also is rolling out notifications for OneDrive file sharing for iOS and Android and access to SharePoint Online files in the OneDrive Android app this week.
"We promised to bring a single sync experience for all your files in Office 365, across OneDrive and SharePoint. Today, we're proud to announce the public preview of this eagerly anticipated update for both PC and Mac," said officials in a blog post outlining the updated feature plans.
"SharePoint sync is being added to the OneDrive sync client, which we released last year, and offers superior levels of reliability, performance and control--including the flexibility to select the specific folders you want to take offline," they continued. "Now you have one simple way to take any of your Office 365 files offline. And we'll make it even easier, with a seamless upgrade from the legacy sync client (groove.exe)."
Microsoft will start rolling out this integrated sync experience to First Release customers "in the coming months", with rollout to all customers slated to be completed in the first quarter of 2017.
