Microsoft have listened to customer feedback, and have delivered a new sync client for OneDrive for Business designed to make OneDrive for Business for Office 365 users faster and more reliable.
This update provides a much improved sync experience so that you always have the latest version of your files accessible from any device.
Microsoft will be rolling out this upgrade over the coming months at which time the previous sync client will then stop working. If you try to sync your files stored in OneDrive for Business using the old sync client, you will be prompted to install the new sync client.
For the best experience in OneDrive for Business, download and set up the Next Generation Sync Client today or view the two-step installation instructions.
