Configure your Yammer network

Do these basic network configuration tasks in the Yammer admin center before you invite users to use Yammer Enterprise so that all users get a consistent experience.

As you're getting started with Yammer, review the links in Yammer admin help for other tasks you might want to do, such as customizing the look of your Yammer network, reviewing security and compliance settings, and making sure your email system is configured properly.

To access the Yammer network configuration tools:

  • In Microsoft 365 or Office 365, go to Admin > Yammer > Configuration.

  • Or, in Yammer, click the Yammer settings icon Yammer settings icon. and go to Network Admin > Configuration.

Set the Yammer network name


In Microsoft 365 or Office 365 Yammer networks, the name in the Microsoft 365 or Office 365 company profile overrides the Network name setting in Yammer. To change the company profile settings, see Change your organization's address, technical contact, and more

  • On the Configuration page, in the Basics section, specify the following:

    • Network name: This is the friendly name of your network that is used in the Yammer header. This name is overwritten by the name used in the Microsoft 365 or Office 365 company profile.

    • Message prompt: This prompt is visible at the top of each Yammer group page, under Update.

Review domains set up to work with your Yammer network

  • On the Configuration page, in the Network Domains section, select Click here to verify that the correct domains are listed. These are the domains that have been set up in Office 365. For more information, see Add a domain to Office 365.

Require users to confirm email messages posted via email before posting

  • On the Configuration page, in the Email Settings section, select whether to require users to confirm messages posted via email before posting.

    For more information about email and Yammer, see Configure email and Yammer.

Restrict who can upload files and limit file formats

  1. On the Configuration page, in the File Upload Permissions section, set which types of files can be uploaded.

  2. To allow unlimited file types, select Allow people to upload and attach files in any format.

    Any number of files, images, or both can be attached to any message or reply, with each file size limited to 5 GB. By default, file attachments are enabled.


    Users will get an error message if they try to upload an image that is wider than 7680 pixels or taller than 4320 pixels.

  3. To restrict who can upload files, clear the Allow people to upload and attach files in any format checkbox. You'll then see three options:

    • Allow people to upload and attach files in any format

    • Only allow people to upload and attach image or video files: Limits attachments to images and videos. Yammer determines file type by extension.

      Yammer uses Azure Media Services to make videos viewable within the network. For more information, see Azure Media Services.

    • Don't allow anyone to upload or attach files: This prevents people from uploading and attaching new files; however, existing attachments aren't be affected.


When files are stored in Yammer, there is no virus check. An admin can export the files and perform an offline virus scan on them, and this process can be automated with custom scripting.

For Microsoft 365 connected Yammer groups that store files in SharePoint, virus checking is done as the file is uploaded. For more information, see Virus dectection in SharePoint Online.


Any admin can delete any file, and group admins can delete files posted to the groups that they manage.

To delete files, a network admin can click the Yammer Settings icon and then click Files. This brings up the Files directory for the entire network. Group admins can delete files posted to a group by going to the Files tab within the group they administer.

Enable or restrict the use of third-party apps

The growing network of partners and developers in Yammer continue to build third-party applications using the Yammer API. To find the list of current apps, including integrations with Microsoft SharePoint, Microsoft Flow, Microsoft Dynamics, and many more business applications, click App Directory on your main Yammer page or go directly to the App Directory.

  • On the Configuration page, in the Enabled Features section, specify whether to allow third party applications.


    Clearing this setting prevents users from adding or accessing these applications. Note that all users, including verified admins, will lose access to apps that were added prior to clearing this setting.


    This setting does not apply to Microsoft 365 or Office 365 connectors that can be added to Microsoft 365 groups. To disable use of these connectors in Yammer, use the following PowerShell command:
    Set-OrganizationConfig -ConnectorsEnabledforYammer:$false
    For more information, see Manage Microsoft 365 Groups with PowerShell. )

Allow Tenor GIFs in messages

By default, users can attach GIFs provided by Tenor, a third-party, to posts.


The GIF search in Yammer defaults to Tenor's "young audience" and "strict" filters in order to keep GIFs appropriate in a school or work setting. If you see inappropriate GIFs in a search, send email to with a link to the GIF.

You can turn off this feature so that users don't see GIFs from Tenor.

  • On the Configuration page, in the Enabled Features section, enable or disable Show Tenor GIFs Search.

By default, when creating a message with a URL, Yammer will fetch content associated with third-party websites, including title, summary, images, and GIFs. Existing URLs that are cached remain until the cache expires.

You can turn off the display of this data for links.

  • On the Configuration page, in the Enabled Features section, enable or disable Fetch URL Content.

Allow users to view an org chart in Yammer

The org chart was deprecated for Office 365 Yammer networks in May 2018. Office charts are available at Skype for Business and Delve. For more information, see Find info from a contact card in Skype for Business and How can I find people and information in Office Delve?

Allow message translation

This feature gives users the option to translate messages from any language supported by Microsoft Translator into the network's default language. To enable this feature, the network admin must accept a Terms and Services agreement in order to use Microsoft's proprietary translation technology. This feature is disabled by default.

When this is enabled, users will see a Translate option right under any message that has been posted in a language different than the language they've selected in Preferences in their Yammer settings.

  • On the Configuration page, in the Enabled Features section, select whether to allow Message Translation.

Set language for system messages

System messages notify users of important actions in the network and conversations, such as creating a new group or adding people to a conversation. Changing the language will display future system messages in the selected language. Prior system messages will remain in the existing language.

  • On the Configuration page, under Set System Language, choose the language to use.

Set Require Admin Approval for external network invitations

Require Admin Approval setting allows network admins to review and allow or deny members of your home network from participating in external networks hosted by other organizations. This setting is OFF be default. Turn this setting ON to review and select whether or not members of your home network can participate in external networks hosted by other organizations.

When this setting is ON, when members from your home network are invited to participate in external networks hosted by other organizations, they can request your approval and you can review pending requests under Pending Requests options under Edit settings in your home network.

To turn this setting to ON, go to Network setting and select External Networks and select the “Require admin approval for members to join other companies' external groups or external networks" to ON.
