Tag in Microsoft Planner

Yes, you absolutely can use "@" tags within Microsoft Planner — though not in the traditional sense.

Using just Power Automate and Planner (no need for the Power Graph API), you can type something like @mark or @karyl (or any custom tag) in a comment, and assign that @tag to a specific email address. You can also create tags based on user roles.

For example, let’s say your team has 50 account managers, but you only want to notify the one(s) assigned to a task — without bothering other team members like developers. You could use something like @am, and Power Automate can be set up to notify only the account manager(s) assigned to that task, instead of tagging each person individually (though that’s also possible if needed).

So yes — you can use custom keywords in the Planner comment section, and Power Automate can pick those up and notify the appropriate individuals.

We are still now almost a year into this one thread with no update as to when this basic functionality will be added.

Please give us some indication that this is even looked at, let alone being worked on. I would like to put my team on Planner, but I'll give up and find something else if we can't even do something this basic.

LOL. YOU are not checking the suggestions. Add the @ function

My guess is that MS is working to integrate Loop inside comment section of tasks in Planner, which will enable this functionality. Doing it the hard way basically.
