Office 365 For Mac

-->

Office for Mac applications provide a native app experience on the macOS platform. Each app is designed to work in a variety of scenarios, including states when no network access is available. When a machine is connected to a network, the applications automatically connect to a series of web-based services to provide enhanced functionality. The following information describes which endpoints and URLs the applications try to reach, and the services provided. This information is useful when troubleshooting network configuration issues and setting policies for network proxy servers. The details in this article are intended to complement the Office 365 URL and address ranges article, which includes endpoints for computers running Microsoft Windows. Unless noted, the information in this article also applies to Office 2019 for Mac and Office 2016 for Mac, which are available as a one-time purchase from a retail store or through a volume licensing agreement.

Most of this article is tables detailing network URLs, type, and description of service or feature provided by that endpoint. Each of the Office apps may differ in its service and endpoint usage. The following apps are defined in the tables below:

  • W: Word
  • P: PowerPoint
  • X: Excel
  • O: Outlook
  • N: OneNote

Office for Mac supports macOS Mojave Dark Mode, so you can focus on your work. Office 365 works across multiple Macs, PCs, tablets and phones and each subscription includes 1 TB of OneDrive cloud storage per person.

Options for reducing network requests and traffic

The default configuration of Office for Mac provides the best user experience, both in terms of functionality and keeping the machine up to date. In some scenarios, you may wish to prevent applications from contacting network endpoints. This section discusses options for doing so.

Disabling Cloud Sign-In and Office Add-Ins

Volume License customers may have strict policies about saving documents to cloud-based storage. The following per-application preference can be set to disable MSA/OrgID Sign in, and access to Office Add-ins.

  • defaults write com.microsoft.Word UseOnlineContent -integer 0

  • defaults write com.microsoft.Excel UseOnlineContent -integer 0

  • defaults write com.microsoft.Powerpoint UseOnlineContent -integer 0

If users try to access the Sign-In function, they will see an error that a network connection is not present. Because this preference also blocks online product activation, it should only be used for Volume License installations. Specifically, using this preference will prevent Office applications from accessing the following endpoints:

Office 365 For Mac Download

  • https://odc.officeapps.live.com

  • https://*.firstpartyapps.oaspapps.com

  • All endpoints listed in the 'Sign In' section above.

  • All endpoints listed in the 'Smart Lookup' section above.

  • All endpoints listed in the 'Product Activation' section above.

  • All endpoints listed in the 'Office Apps (aka add-ins)' section above.

To re-establish full functionality for the user, either set the preference to '2' or remove it.

Note

This preference requires Office for Mac build 15.25 [160726] or later.

Telemetry

Office for Mac sends telemetry information back to Microsoft at regular intervals. Data is uploaded to the 'Nexus' endpoint. The telemetry data helps the engineering team assess the health and any unexpected behaviors of each Office app. There are two categories of telemetry:

  • Heartbeat contains version and license information. This data is sent immediately upon app launch.

  • Usage contains information about how apps are being used and non-fatal errors. This data is sent every 60 minutes.

Microsoft takes your privacy very seriously. You can read about Microsoft's data collection policy at https://privacy.microsoft.com. To prevent applications from sending 'Usage' telemetry, the SendAllTelemetryEnabled preference can be adjusted. The preference is per-application, and can be set via macOS Configuration Profiles, or manually from Terminal:

defaults write com.microsoft.Word SendAllTelemetryEnabled -bool FALSE

Office 365 For Mac Free

defaults write com.microsoft.Excel SendAllTelemetryEnabled -bool FALSE

defaults write com.microsoft.Powerpoint SendAllTelemetryEnabled -bool FALSE

defaults write com.microsoft.Outlook SendAllTelemetryEnabled -bool FALSE

defaults write com.microsoft.onenote.mac SendAllTelemetryEnabled -bool FALSE

defaults write com.microsoft.autoupdate2 SendAllTelemetryEnabled -bool FALSE

defaults write com.microsoft.Office365ServiceV2 SendAllTelemetryEnabled -bool FALSE

Office 365 For Mac Versions

Heartbeat telemetry is always sent and cannot be disabled.

Office 365 For Mac Version

Crash reporting

When a fatal application error occurs, the application will unexpectedly terminate and upload a crash report to the 'Watson' service. The crash report consists of a call-stack, which is the list of steps the application was processing leading up to the crash. These steps help the engineering team identify the exact function that failed and why.

In some cases, the contents of a document will cause the application to crash. If the app identifies the document as the cause, it will ask the user if it's okay to also send the document along with the call-stack. Users can make an informed choice to this question. IT administrators may have strict requirements about the transmission of documents and make the decision on behalf of the user to never send documents. The following preference can be set to prevent documents from being sent, and to suppress the prompt to the user:

defaults write com.microsoft.errorreporting IsAttachFilesEnabled -bool FALSE

Note

If SendAllTelemetryEnabled is set to FALSE, all crash reporting for that process is disabled. To enable crash reporting without sending usage telemetry, the following preference can be set: defaults write com.microsoft.errorreporting IsMerpEnabled -bool TRUE

Updates

Microsoft releases Office for Mac updates at regular intervals (typically once a month). We strongly encourage users and IT administrators to keep machines up to date to ensure the latest security fixes are installed. In cases where IT administrators want to closely control and manage machine updates, the following preference can be set to prevent the AutoUpdate process from automatically detecting and offering product updates:

Contents.WoW System Requirements Minimum system requirements (as of 20-Oct-2010). Wow for mac. Mac OS X 10.5.8, 10.6.4, or newer.

defaults write com.microsoft.autoupdate2 HowToCheck -string 'Manual'

Blocking Requests with a Firewall/Proxy

If your organization blocks requests to URLs via a firewall or proxy server be sure to configure the URLs listed in this document as either allowed, or block listed with a 40X response (e.g. 403 or 404). A 40X response will allow the Office applications to gracefully accept the inability to access the resource, and will provide a faster user experience, than simply dropping the connection, which in turn will cause the client to retry.

Microsoft Office For Mac

If your proxy server requires authentication, a 407 response will be returned to the client. For the best experience, ensure that you're using Office for Mac builds 15.27 or later, as they include specific fixes for working with NTLM and Kerberos servers.
