Create and manage an external network in Yammer
If you have permission, you can create an external Yammer network to collaborate with people outside your company, such as customers, suppliers, and partners. People with external email addresses must be invited into or request access to an external network. When they join the external network, they can only see content posted specifically to that external network. That means they will not have access to your home network.
External networks are essentially their own networks: each has its own admin center and has its own admins.
Create an external network
Select the Yammer settings icon , and then go to Networks > Create a New Network.
The Yammer admins for your home network control whether all users or only admins can set up external networks. If Create a New Network is not visible, it means your Yammer admins have configured your Yammer network to only allow Yammer network and verified admins to create an external network.
To ask one of your home network admins for help setting up an external network, look in the All Company group in your home network. Admins have blue stars by their names.
Fill in the required settings:
Network Image: Click Choose File to select an image to use in the header for your new external network.
Network Name: Provide a name for your new external network, which will now have its own email address and URL. This name must be unique - no other company can use the same name. The URL will be
with any spaces removed from the network name. You may want to include your company name, such as Contoso Customer Feedback. In this example, the URL would be
Network Description: A clear and succinct description ensures users understand the basic purpose of this network.
Add a Network Image: Upload a thumbnail image or logo that represents the new network.
Permissions: Select whether membership is Open (where all members can invite new members) or Closed (where only admins can invite new members). You can also select whether or not members of your company's home network can join without an invitation.
Allow members to join without an invite: When you select this, users can join without an invite. When you clear this checkbox, users in your home network must request approval before joining this external network.
Click Create Network.
The top bar of your network shows that you're now in the external network. The settings icon for the external network has a blue circle in it.
The All Network group is automatically created. This group can't be deleted. Users can create additional groups.
To start inviting people to join your external network, click the external network settings icon , and then click Invite.
Email notification settings that each user set for the home network don't apply to the new external network. Users must set email notifications for each external network. For more information, see Yammer email and push notifications.
Go to and from an external network
To get to an external network from your home network, click the Yammer settings icon , and then near the bottom of the settings list, select the external network, or select Browse External Networks.
For example, if you select Contoso Customer Feedback in the first screenshot, you'll go to a new Yammer site for the Contoso Customer Feedback external network. The settings icon will have a blue dot to indicate you're in an external network. The URL will change to show the external network name. For example for the Contoso Customer Feedback external group, the URL is https://yammer.com/ContosoCustomerFeedback.
To get back to your home network, click the home network name at the end of the settings list.
Manage settings for an external network that you are an admin for
To go to your external network, click the Yammer settings icon , and then select an external network, or select Browse External Networks.
In your external network, click the external network settings icon .
Select Network Admin to configure and design your external network. For information on these settings, see Configure your Yammer network.
Note that not all settings are available for external networks: you can't create another external network from an existing external network, invite guests, or monitor a person's account activity. > End users who create an external network have fewer configuration options. End users can modify the Configuration, Design, and Usage Policy settings, as well as create additional admins and manage users. They can't bulk update users or change anything in the Content and Security section.
Delete an external network
Deleting an external network deletes all content in the external network and removes all members from the network. Once a network is deleted, it can't be reactivated.
To go to an external network, click the Yammer settings icon, and then select an external network, or select Browse External Networks.
In the external network, click the external network settings icon .
Go to Network Admin > Configuration.
At the bottom of the page, click Delete External Network, and then on the confirmation page, click Delete.
