Office 2016 for Mac, macOS Sierra potential crash issues

Last updated: November 2016

ISSUE

Apple released macOS 10.12 Sierra on 9/20/2016. Some customers are reporting Office 2016 for Mac applications are closing unexpectedly, or crashing when an Office application is launched, or when the computer is moved between Wi-Fi networks (e.g. moving a laptop from home to work).

Microsoft is working with Apple to resolve this issue. We recommend customers in a workplace or school network configuration do not upgrade to macOS Sierra at this time.

WORKAROUND

Turning off “Auto Proxy Discovery” or “Automatic Proxy Configuration” is a possible workaround, if allowed by your organization’s network configuration.

  1. Go to System Preferences and open Network.

  2. Click on Advanced and go to Proxies.

  3. Check if "Auto Proxy Discovery" or "Automatic Proxy Configuration" is turned on.

Contact your local network administrator for more information on your network settings.

We will update this content when more information is known, including a fix or additional workaround.
