What is Microsoft Power Automate?

Microsoft Power Automate (formerly Microsoft Flow) is a cloud-based service that allows users to create automated workflows to streamline repetitive tasks.

It integrates with Microsoft 365 apps (e.g., SharePoint, Excel, Outlook) and third-party services, enabling users to automate processes without coding.

For reminder emails, Power Automate can trigger notifications based on schedules, data changes, or specific conditions, such as due dates in a SharePoint list or Excel table.

Key benefits of using Power Automate for reminder emails include:

• Time Savings: Automate repetitive tasks like sending reminders, reducing manual effort.
• Customizability: Tailor email content, recipients, and schedules to meet specific needs.
• Integration: Connects seamlessly with Microsoft 365 apps and external services like Gmail.
• Scalability: Suitable for individual users, small teams, or large organizations.

Why Automate Reminder Emails?

Automating reminder emails addresses common challenges in task management:

• Prevent Missed Deadlines: Ensure timely notifications for due dates or pending actions.
• Reduce Manual Work: Eliminate the need to manually send reminders.
• Enhance Productivity: Keep teams focused by automating repetitive communication.
• Improve Accountability: Track tasks and ensure follow-through with automated prompts.

For example, you might need to remind team members about tasks due in 7 days, send approval reminders for pending requests, or notify staff to complete a Microsoft Form. Power Automate makes these scenarios achievable with minimal setup.

Prerequisites for Automating Reminder Emails

Before setting up a reminder email flow, ensure you have:

• Microsoft 365 Subscription: Access to Power Automate, typically included in Microsoft 365 plans. A free plan is available for basic flows, but some features require a premium license.
• Data Source: A SharePoint list, Microsoft List, or Excel file stored in OneDrive for Business or SharePoint with relevant data (e.g., due dates, assignees, email addresses).
• Date Column: A column in your data source with Date and Time format for triggering reminders.
• Outlook Account: An Office 365 Outlook account for sending emails (or another email service like Gmail for non-Microsoft ecosystems).
• Permissions: Access to create and manage flows in Power Automate and read/write permissions for the data source.

Step-by-Step Guide to Automating Reminder Emails

Below is a detailed guide to creating a Power Automate flow for sending reminder emails based on a SharePoint list or Microsoft List with a due date column.

This example uses the Microsoft Lists Issue Tracker template, sending reminders 30 days before a due date, but the steps can be adapted for other scenarios (e.g., Excel, forms, or approvals).

Step 1: Set Up Your Data Source

1. Create a Microsoft List or SharePoint List:
   • Navigate to Microsoft Lists or SharePoint.
   • Select New List > Issue Tracker (or create a custom list).
   • Provide a name, color, icon, and storage location (e.g., My Lists or SharePoint).
   • Add a Due Date column (Date and Time format) to track deadlines.
2. Add Sample Data:
   • Populate the list with tasks, including columns for Due Date, Assignee, and Email (or use the “Person or Group” column for assignees).

Step 2: Create a Scheduled Cloud Flow

1. Access Power Automate:
   • Sign into Power Automate using your Microsoft 365 account.
   • Click Create > Scheduled Cloud Flow.
2. Configure the Recurrence Trigger:
   • Name the flow (e.g., “Issue Tracker – Daily Reminder”).
   • Set the start date and time (e.g., 10:00 AM).
   • Set Repeat every to “1 Day” for daily checks.
   • Use Advanced options to set the time zone (e.g., UTC or your local time zone).
3. Save and Proceed:
   • Click Create to initialize the flow.

Step 3: Retrieve Items from the Data Source

1. Add a Get Items Action:
   • Click New Step > Search for “SharePoint” > Select Get items action.
   • Set Site Address to your SharePoint site or Microsoft List location.
   • Set List Name to your list (e.g., Issue Tracker).
2. Filter for Due Dates:
   • In Advanced options, add an ODATA filter query to retrieve items due in 30 days. Use the format:DueDate eq '@{formatDateTime(addDays(utcNow(), 30), 'yyyy-MM-dd')}' This filters items where the Due Date matches 30 days from the current date.
   • Ensure the date format matches your SharePoint list (ISO 8601, e.g., YYYY-MM-DD).

Step 4: Send Reminder Emails

1. Add a Send Email Action:
   • Click New Step > Search for “Office 365 Outlook” > Select Send an email (V2).
   • Power Automate automatically adds an Apply to each loop to process multiple items from the Get items action.
2. Configure Email Details:
   • To: Select the dynamic content for the assignee’s email (e.g., “Person or group the issue is assigned to Email”).
   • Subject: Enter a subject like “Reminder: Task Due in 30 Days”.
   • Body: Customize the email body with static text and dynamic content (e.g., task title, due date). Example:Hello [Assignee Name], Your task "[Task Title]" is due on [Due Date]. Please review and take action. Regards, [Your Name] Use dynamic content from the Get items action to populate fields.
3. Optional Formatting:
   • Use the rich text editor to format the email (e.g., bold text, colors) or add HTML for advanced styling.

Step 5: Save and Test the Flow

1. Save the Flow:
   • Click Save to store the flow configuration.
2. Test the Flow:
   • Click Test > Manually > Run Flow to simulate the flow.
   • Check the recipient’s inbox to confirm the email was sent correctly.
3. Verify Run History:
   • Go to My Flows > Select your flow > View Run History to check inputs and outputs for troubleshooting.

Step 6: Customize for Advanced Scenarios

• Multiple Reminders: Add additional Get items actions with different filter queries (e.g., 7 days, 1 day before due date).
• Conditional Logic: Use a Condition action to check task status (e.g., only send reminders for “Pending” tasks).
• Summary Emails: Create a single email summarizing multiple due tasks using the Create HTML Table action.
• Escalation Emails: Send escalation emails to secondary recipients (e.g., managers) if tasks remain incomplete after the due date.

Example: Automating Reminders from Excel

For users storing tasks in an Excel file (stored in OneDrive for Business or SharePoint), follow these steps:

1. Prepare the Excel Table:
   • Format your data as an Excel table (Ctrl+T) with columns like Task, Due Date, Assignee, and Email.
2. Create a Scheduled Flow:
   • Follow Step 2 above to set up a daily recurrence trigger.
3. Add List Rows Action:
   • Add an Excel Online (Business) > List rows present in a table action.
   • Select the Excel file and table name.
   • Use a filter query to retrieve rows where the due date matches the desired reminder date (e.g., 7 days from now).
4. Send Emails:
   • Add a Send an email (V2) action within an Apply to each loop to process each row.
   • Populate the email with dynamic content from the Excel table (e.g., Task, Due Date).
5. Test and Save:
   • Test the flow to ensure emails are sent correctly and save the configuration.

Example: Automating Form Submission Reminders

To remind users who haven’t completed a Microsoft Form:

1. Set Up a SharePoint List:
   • Create a list to track form submissions with columns for Email, Completed (Yes/No), and Submission Date.
2. Create a Flow for Form Submission:
   • Trigger: Microsoft Forms > When a response is submitted.
   • Action: Update the SharePoint list with the respondent’s email and set Completed to “Yes”.
3. Create a Scheduled Reminder Flow:
   • Trigger: Daily recurrence.
   • Action: Get items from the SharePoint list where Completed is “No”.
   • Action: Send an email (V2) to remind users to complete the form.
4. Test and Monitor:
   • Ensure the flow only targets non-respondents and stops sending reminders once the form is submitted.
