As part of its rebranding of Yammer to Viva Engage last week, Microsoft added the Viva Engage Core service plan to user accounts. Which is nice, unless a tenant had blocked Yammer. The new service plan means that accounts can now use Yammer In many cases, it won’t matter too much that users can now access Yammer, but in other instances it will. In any case, we should tidy up by removing the Viva Engage Core service plan from any account that already blocks Yammer. Some PowerShell does the trick, but it would have been nice if Microsoft had thought things through a little more.
