Planner task comments no longer send email notifications – critical regression
This change removed a previously existing core functionality without providing an adequate replacement. With the new Planner experience, task comments no longer trigger automatic email notifications...
We noticed similar behavior recently in a few Microsoft 365 environments. In many cases, the issue was related to notification sync delays or backend changes in Planner/Exchange Online rather than user settings themselves. It’s worth checking whether email notifications are still enabled under Planner settings and verifying if affected users are receiving any other M365 alerts normally. A temporary workaround we used was relying on Teams activity notifications until Microsoft resolved the sync issue.
