Note

Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.

Start quickly with the most recent versions of Word, Excel, PowerPoint, Outlook, OneNote and OneDrive —combining the familiarity of Office and the unique Mac features you love. Work online or offline, on your own or with others in real time—whatever works for what you’re doing. For example, go to Word and choose About Word. In the dialog box that opens, you can see the version number as well as the license type. In the example below, the version number is 16.18 and the license is a one-time purchase of Office 2019 for Mac.

If you're an Office Insider, see Release notes for Mac Beta Channel.; Starting with the 16.17 release in September 2018, these release notes also apply to Office 2019 for Mac, which is a version of Office for Mac that’s available as a one-time purchase from a retail store or through a volume licensing agreement. If your version of Microsoft Office is older than Office 2016 v15.35, you’ll have to choose from a variety of costly or time consuming and complicated options.

Symptoms

When you try to activate or sign in to any of the Microsoft Office 2016 applications after you install the version 15.33 update, you receive a blank authentication screen. Additionally, you may see any of the following symptoms.

Symptom 1

The following issues occur in the Unified Logging Service (ULS) log:

• The server has redirected to a non-https URL.
• Errors occur in Azure Active Directory Authentication Library (ADAL) authentication.

To locate the ULS log, open Finder and browse to the following path:

~/Library/Containers/com.microsoft.<Application>/Data/Library/Caches/Microsoft/uls/com.microsoft.<Application>/logs

Note <Application> represents the name of the application that you are troubleshooting.

Symptom 2

You notice that in an HTTP trace, the server response includes multiple WWW-Authenticate headers, such as the following:

WWW-Authenticate: Negotiate

WWW-Authenticate: NTLM

Cause

The symptoms occur for the following corresponding reasons:

Cause for symptom 1

Starting from Office 2016 for Mac version 15.33, unsecured endpoint traffic is blocked in authentication flows.

Cause for symptom 2

Starting from Office 2016 for Mac version 15.33, the authentication method no longer selects NTLM authentication when multiple WWW-Authenticate headers are present in the response. The issue occurs when the selected authentication method is unsuccessful.

Resolution

Resolution for symptom 1

Configure all authentication endpoints to use the Secure Sockets Layer (SSL) protocol.

Resolution for symptom 2

Install the September 2017 update for Office 2016 for Mac version 15.38.

The resolution applies when you use Microsoft Active Directory Federation Services or non-Microsoft federation solutions.
