Planner task comments no longer send email notifications – critical regression
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.
Thank you for your input.
We initially considered the possibility of a notification sync issue as well. However, after opening a support case with Microsoft and having the behavior reviewed by the Planner support team, Microsoft confirmed that this is not a synchronization problem, a configuration issue, or a temporary service degradation.
According to Microsoft Support, the previous Planner comment functionality has been intentionally replaced by the new task chat experience. As part of this change, automatic email notifications for task discussions have been removed and there is currently no supported way to restore the previous behavior.
Microsoft further confirmed that @mentions within the task chat are now the only supported mechanism to trigger email notifications for individual users.
Therefore, at least in our case, this appears to be a product design change rather than a notification delivery issue.
Thank you for sharing your experience nonetheless. It would be interesting to hear whether other organizations have found a practical workaround for maintaining reliable task-related notifications.
