“The server you are trying to access is using an authentication protocol not supported by this version of Office” error in OneDrive for Business

PROBLEM
You sync a OneDrive for Business library by using the OneDrive for Business sync client (groove.exe). However, you receive the following error message:
Unsupported server
The server you are trying to access is using an authentication protocol not supported by this version of Office


Note To determine which OneDrive sync client you’re using, see the following Microsoft website:

Solution

A fix was released for the Click-to-Run version of the OneDrive for Business sync client. By default, Click-to-Run installations of Microsoft Office 2013 and Office 2016 are configured to automatically update your Office installation when new updates are made publicly available. If your Click-to-Run version of Office doesn't update automatically, see the following Microsoft website:
2753538 Automatic updating for Office 2013 and Office 2016 Click-to-Run is not enabled  
 
For the MSI installation, the issue will be resolved in a future update of Office. Until the update is released, you can use the Workaround in this article.
WORKAROUND
To work around this issue, follow these steps:
  1. Start an Office application that isn't OneDrive for Business. For example, start Word, Excel, or PowerPoint.
  2. Click the File tab, click Account, and then click Switch account.
  3. Click Add Account and then enter the Office 365 account that uses OneDrive for Business.

    Note Click SIGN OUT for any accounts other than the Office 365 account that uses OneDrive for Business.
  4. Exit the application that you opened in step 1.
  5. Exit OneDrive for Business. To do this, follow these steps:
    1. Right-click the OneDrive for Business cloud icon on the taskbar.
    2. Click Exit.
  6. Start OneDrive for Business. To do this, follow these steps:

  7. Sync the OneDrive for Business library. To do this, follow these steps:

    2. Click Sync now.
Note If these steps don’t resolve the issue, you may have to remove all accounts that are signed in except for the Office 365 account. Then, try to sync the OneDrive for Business library. After the library syncs successfully, you can add those accounts back. To do this, follow these steps:
  1. Start an Office application that isn't OneDrive for Business. For example, start Word, Excel, or PowerPoint.
  2. Click the File tab, and then click Account.
  3. Under Connected Services, click Remove for any service that isn't for the Office 365 account.
  4. Exit the application that you opened in step 1.
  5. Exit OneDrive for Business. To do this, follow these steps:
    1. Right-click the OneDrive for Business cloud icon in the taskbar.
    2. Click Exit.
  6. Start OneDrive for Business. To do this, follow these steps:
    1. Click Start, and then type OneDrive for Business.
    2. Click the OneDrive for Business app.
