Solution 1Recommended

Add Yammer Basic Domains to Your Office 365 Tenant

Follow Microsoft's official procedure to consolidate Yammer Basic networks into your primary Microsoft 365 tenant to prevent data loss.

When Yammer Basic networks are deprecated, organizations must associate their Yammer domains with their active Microsoft 365 subscription to preserve their data.

Not all network data may qualify for a direct migration. Adding and verifying the basic domains within the Office 365 tenant is the critical first step to evaluate migration eligibility.

1
Access the Microsoft 365 Admin Center

Log in to the Microsoft 365 admin center using your global administrator credentials.

2
Navigate to Domains

Go to the 'Settings' menu on the left sidebar and select 'Domains'.

3
Add and Verify the Yammer Domain

Click 'Add domain', enter the domain associated with your Yammer Basic network, and follow the DNS verification prompts to prove ownership.

4
Review Yammer Network Consolidation

Once verified, navigate to the Yammer admin center and access the 'Network Migration' section to review consolidation settings and determine if your data qualifies for migration.

Once the Yammer Basic networks are officially deprecated by Microsoft, unmigrated data will be permanently deleted, and users will lose access to the free network.

Not necessarily. You must verify your domain in the Microsoft 365 admin center to determine if your specific network data qualifies for migration according to Microsoft's deprecation policies.

Only users assigned the Global Administrator or verified Yammer Network Administrator roles within the Microsoft 365 tenant can authorize and execute the domain consolidation.
