Control the File Transfer feature in the Office app

Note

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

Introduction

The File Transfer feature in the Microsoft Office app lets you send files from your mobile device to your computer, and receive files from your computer or device. For more information about the feature, see Transfer files in the Office app for Android and iOS.

Note

You can transfer only locally stored, non-managed data from a mobile phone to the desktop. You can't transfer Intune-protected, organization-managed, or cloud files. The File Transfer feature follows the policies for Intune Mobile Application Management (MAM) that are applied on the Office app.

Turn off File Transfer

In certain scenarios, you may want to restrict the use of the File Transfer feature in your environment. To turn off the feature for your organization, use one of the following methods.

Method 1: Block URLs

Block the following URLs:

  • filetransfer-prod-griffin-*.cloudapp.net
  • transfer.office.com
  • filetransfer.trafficmanager.net

Note

In some settings, you cannot block https://transfer.office.com/ because it's part of the allowed (whitelisted) *.office.com class of URLs. This is not a concern because https://transfer.office.com/ redirects to one of the other URLs that are mentioned in the list. If you post the blocking, your users in the organizational firewalls will be unable to use this feature for sending or receiving files.

Method 2: Block IP addresses

Depending on how the firewall is configured, you may have to block the following IP addresses:

  • 13.76.241.194
  • 52.184.64.21
  • 65.52.31.49
  • 70.37.107.67
  • 52.169.19.3
