Hello Sena!
Here’s how you can add Planner to a specific channel in Microsoft Teams—not just the General channel:
Go to the Channel: Open the desired team in Microsoft Teams and click on the specific channel (not the General one).
Add a Tab: Click the "+" (plus) sign at the top of the channel to add a new tab.
Select Planner (Tasks by Planner and To Do): From the list, choose “Planner” (it may show as “Tasks by Planner and To Do”).
Create or Add an Existing Plan: You can either create a new plan or add an existing one.
Save: After adding, Planner will appear as a tab within that channel.
Note: If this option does not appear or is disabled, your organization’s Teams settings or permissions may restrict adding Planner to multiple channels. In this case, contacting your IT admin may help.
As seen in recent video guides, this feature is available, but permissions or recent policy changes can sometimes impact availability.
