Yammer External MessagingYammer External Messaging lets users invite external participants (for example, customers, partners, vendors, and so on) to conversations within their Yammer network.
So that Yammer can help provide a safe and secure environment, External Messaging includes security controls to help identify, monitor, and proactively protect your corporate intellectual property (IP).
Using Exchange transport rules to control YammerAs Yammer evolves to foster team collaboration and external discussions, we're building organizational control capabilities that resemble those that are available in email. Just as email offers Exchange transport rules (ETRs) that govern external communications, Yammer Verified Admins will be able to apply these same protections in their network. This opt-in feature will provide proactive controls to help protect employee communications. For more information about ETRs, go to the following Microsoft website:
When it’s first released, Yammer will interpret any existing ETR as a reason to turn off External Messaging. Soon after the first release, Yammer will ignore rules that use only the action SetSCL. This action isn’t relevant for controlling external communications. At the time that we're publishing this article, there is no public roadmap for when Yammer will start to interpret other ETRs.
Verified Admins who want to apply ETRs from Microsoft Exchange Online to Yammer can opt in to this functionality, on a per-network basis, by selecting that option within the admin panel. This Yammer admin capability will become available in the product in early May 2015. For it to take effect, the Yammer network has to be connected to an Office 365 organization. You can do this by activating Yammer Enterprise in the Office 365 admin center.
Expanding data exportRetention of conversations and content is very important for many organizations in meeting their eDiscovery needs. With the launch of External Messaging, we have updated data export to help companies identify and monitor potential risks. By using data export, Verified Admins can see which conversations and files in their network are visible to external participants and can identify conversations in which their employees are participating on other Yammer networks. For example, if one of your employees is participating in a conversation on another Yammer network, your Verified Admins can view the entirety of this conversation through data export. Yammer's aim is to closely match the eDiscovery requirements of email to provide a consistent experience across communication modalities.
Improving the user interface (UI)To help make sure that you have simple and safe communication, we've improved the Yammer UI to prevent the accidental sharing of information. This UI was validated through usability testing to make sure that users are fully aware of their actions before they invite external participants or comment on a post that’s visible to external participants.
Some examples of the UI changes are as follows:
If these changes aren’t enoughWe're excited to share these new features with you. But we also realize that External Messaging may affect the way that your network uses Yammer.
Even with ETRs, data export improvements, and an updated UI, if your organization can't accommodate enabling this new capability at this point, you will also have an option to block users from inviting external people to participate in conversations in your Yammer network. Blocking users in this manner makes sure that external users can't view content within your home network by using External Messaging.
Separately, there is the option to firewall users from replying when external users in other Yammer networks (such as partner or customer organizations) invite your coworkers into their conversations. However, we highly discourage firewalling your users in this manner because it will cause your users to seem difficult to reach and to collaborate with, and will result in users receiving the Yammer equivalent of an email bounce.
Network administrators who want to block users from inviting external people or who want to firewall their users from incoming messages should contact Microsoft Support.
As we continue innovating Yammer, we are likely to build additional capabilities as part of the External Messaging framework. Blocking external sharing, and firewalling users in particular, will make some future Yammer capabilities (for example, External Groups) unavailable to your users. Because such a decision on your part could lead to a decreased user experience over time and a suboptimal version of Yammer, we highly recommend that you assess whether ETRs, data export improvements, and updates to the UI are sufficient to meet your needs.
How to prevent outbound communications or firewall your usersIn order to prevent outbound communications or to firewall your users, you must submit a support ticket. After you submit a ticket, you'll be contacted by a support representative who will help you with the process. To make sure that you have the best experience, we require you to have the answers to the following questions ready before you open a ticket:
- Which of the following opt-out options do you want?
- Blocking outbound communication
- Firewalling users
- Which domains of each network do you want to opt out of? (Specify whether that network is an external network.)
- Why are you opting out?
