Question details

The administrator needs to bulk export user, group, membership, and administrator data from Yammer or Viva Engage prior to a SharePoint network migration.

Product: Yammer / Viva Engage
Device & OS: not provided
Scenario: Performing a network migration to SharePoint and needing to export organizational data efficiently.
Observed behavior: The goal is to export complete user and group directories without having to extract each user individually.

Before you start

Ensure you have verified administrator privileges in your Yammer or Viva Engage network and possess a valid OAuth token for API access before running any PowerShell scripts.

Solution 1Recommended

Export Data Using a PowerShell Script and Yammer API

Use a PowerShell script authenticated with a Yammer OAuth token to export comprehensive user and group data directly into CSV files.

This method utilizes the REST API to programmatically fetch network details, which is highly customizable for bulk migrations.

Generate an API Token

Log into your Yammer/Viva Engage developer console, register an application, and generate a verified admin OAuth token.

Prepare the PowerShell Script

Create or download a PowerShell script designed to query the Yammer REST API endpoints for users, groups, and administrators.

Authenticate the Request

Insert your generated OAuth token securely into the script's authorization header to authenticate the API requests.

Run the Export

Execute the script in PowerShell. The script will retrieve the network data and export the results into properly formatted CSV files.

Security Best Practice: Always protect your OAuth tokens. Do not hardcode them into scripts that will be shared publicly or stored in unencrypted repositories.

Solution 2

Use the Native Export Network Data Feature

Utilize the built-in Yammer export feature as a no-code alternative to PowerShell scripts.

Frequently Asked Questions

Do I need Global Admin rights to export Viva Engage network data?

Yes, exporting complete network data—including detailed user and group structures via the API or native export tools—typically requires Network Admin, Verified Admin, or Global Admin privileges.

Can I export Yammer private group memberships using PowerShell?

Yes, but you must authenticate your PowerShell script using an OAuth token generated by a Verified Admin account. This grants the API visibility into private groups for data export.

In what format is the native Export Network Data delivered?

The built-in Export Network Data tool delivers a .zip archive. This archive contains multiple .csv files neatly separated into categories like users, groups, messages, and files.

Do Yammer API OAuth tokens expire during long data exports?

Yammer OAuth tokens generally do not expire automatically unless they are manually revoked by the user or administrator. However, it is recommended to implement error handling in your PowerShell script to catch and log any unexpected authentication failures.
