How to Send Microsoft Planner Reminders Before a Due Date

Log into your Microsoft 365 account and navigate to the specific board in Microsoft Planner.

Click on the three horizontal dots (...) at the top of the planner board and select 'Add plan to Outlook calendar' from the dropdown menu.

Choose to publish the plan and click 'Add to Outlook'. This action will open Outlook on the web and integrate the task calendar.

Open the synced task events in your Outlook calendar and manually adjust the reminder time to your preferred advance notice (for example, 2 days or 1 week before the due date).

Log in to Microsoft Power Automate and click on 'Create' on the left sidebar to start a new flow.

Select 'Scheduled cloud flow', name your flow, and set it to repeat every 1 day to ensure it checks deadlines daily.

Add a new step, search for the Planner connector, and select the 'List tasks' action. Choose the specific Plan ID you want to monitor.

Add a 'Condition' step. Set the logic to check if a task's due date is exactly your desired number of days from the current date.

In the 'If yes' branch, add the 'Send an email (V2)' action to dispatch an automated alert to the task's assigned user regarding the approaching deadline.
