by

Setting a reminder in Outlook ensures you never miss an important deadline or meeting. Knowing how to create a reminder in Outlook can save you from missed appointments and forgotten tasks. This guide walks you through every method, from desktop to mobile, with clear steps.

Reminders are built into Outlook’s calendar, tasks, and email systems. They pop up at a set time before an event, giving you a nudge. You can customize them for any need.

How To Create A Reminder In Outlook

This section covers the core method for adding reminders to calendar events. It works in Outlook 2016, 2019, 2021, and Microsoft 365.

Step-By-Step For Calendar Events

  1. Open Outlook and go to the Calendar view.
  2. Click “New Event” or double-click a time slot.
  3. Fill in the event details like subject, location, and time.
  4. Look for the “Reminder” dropdown menu near the top.
  5. Select a time frame, such as 15 minutes, 1 hour, or 1 day before.
  6. Click “Save & Close” to confirm.

Thats it. The reminder will appear as a pop-up at your chosen time. You can also set it to “None” if you don’t want one.

Customizing Reminder Time

You can choose from preset times or type a custom value. For example, type “2 hours” or “3 days” directly into the box. Outlook accepts minutes, hours, days, or weeks.

  • Minutes: 5, 10, 15, 30
  • Hours: 1, 2, 4, 8
  • Days: 1, 2, 3, 7
  • Weeks: 1, 2

If you need a reminder 45 minutes before, just type “45 minutes” and press Enter. The system will remember your custom value for future events.

Setting Reminders For Tasks

Outlook Tasks also support reminders. This is helpful for to-do items that aren’t tied to a specific time slot. You can set a due date and a reminder time.

How To Add A Reminder To A Task

  1. Open the Tasks module in Outlook.
  2. Click “New Task” or double-click an existing task.
  3. Enter the task subject and details.
  4. Check the box “Reminder” near the bottom.
  5. Set the date and time for the reminder.
  6. Click “Save & Close”.

Tasks reminders work like calendar ones. They pop up even if Outlook is minimized. You can snooze or dismiss them.

Using Flagged Emails As Tasks

You can flag an email to turn it into a task with a reminder. This is a quick way to track follow-ups.

  1. Right-click the email in your inbox.
  2. Select “Follow Up” and then “Add Reminder”.
  3. Set the due date and reminder time in the dialog box.
  4. Click “OK”.

The email appears in your Tasks list with a reminder attached. You can also set a flag without a reminder by choosing a quick flag option.

Managing Default Reminder Settings

You can change the default reminder time for all new events. This saves time if you always want a 30-minute notice.

Changing Default For Calendar

  1. Go to File > Options > Calendar.
  2. Under “Calendar options”, find “Default reminders”.
  3. Check the box to enable it, then set your prefered time.
  4. Click “OK” to save.

Now every new event you create will use this default. You can still override it for individual events.

Changing Default For Tasks

Task defaults work similarly. Go to File > Options > Tasks. Check “Set reminders on tasks with due dates” and choose a time. The default is 9:00 AM on the due date.

This setting only applies to new tasks. Existing tasks won’t change unless you edit them manually.

Using Reminders On Outlook Mobile

The Outlook app for iOS and Android supports reminders too. The process is slightly different but just as easy.

Creating A Reminder In The Mobile App

  1. Open the Outlook app on your phone.
  2. Tap the calendar icon at the bottom.
  3. Tap the “+” button to create a new event.
  4. Fill in the event details.
  5. Scroll down to “Reminder” and tap it.
  6. Choose a time from the list or tap “Custom”.
  7. Tap “Save” in the top corner.

The app will send a notification at the set time. Make sure notifications are enabled for Outlook in your phone settings.

Reminders For Tasks On Mobile

Tasks in the mobile app also have reminders. Tap the tasks icon (checkmark) at the bottom. Create a new task, then tap “Reminder” to set it. The process mirrors the desktop version.

Using Cortana Or Voice Commands

If you use Cortana with Outlook, you can set reminders by voice. This works on Windows 10 and 11 with Cortana enabled.

Voice Reminder Steps

  1. Say “Hey Cortana, set a reminder”.
  2. Specify the event and time, like “for meeting at 3 PM tomorrow”.
  3. Cortana will create a calendar event with a default reminder.
  4. You can also say “remind me to call John in 30 minutes”.

These reminders sync with Outlook if your accounts are linked. It’s a hands-free way to manage your schedule.

Common Issues And Fixes

Sometimes reminders don’t work as expected. Here are frequent problems and solutions.

Reminder Not Showing Up

  • Check that Outlook is running in the background.
  • Verify your default reminder settings are enabled.
  • Make sure the event or task has a reminder set.
  • Restart Outlook and try again.

Reminder Sound Not Working

  • Go to File > Options > Advanced.
  • Under “Reminders”, click “Reminder Options”.
  • Check “Play reminder sound” and choose a .wav file.
  • Test the sound in your system settings.

Reminders For Past Events

Outlook won’t show reminders for events that have already passed. If you missed one, check your calendar for the event and set a new reminder.

Advanced Tips For Power Users

These tricks help you get more from reminders. They work best for frequent Outlook users.

Using Categories With Reminders

You can assign categories to events with reminders. This helps you filter and find them later.

  1. Create an event with a reminder.
  2. Click “Categorize” in the ribbon.
  3. Choose a color category.
  4. Now you can search by category to see all reminders.

Recurring Events With Reminders

For weekly meetings, set a recurring event. The reminder applies to every occurrence.

  1. Create a new event.
  2. Click “Recurrence” in the ribbon.
  3. Set the pattern (daily, weekly, monthly).
  4. Set the reminder as usual.
  5. Save the event.

Each instance will have the same reminder. You can change it for individual occurrences if needed.

Sharing Calendars With Reminders

When you share your calendar, others see your events but not your reminders. Reminders are personal and don’t appear on shared calendars.

Reminders For Emails

You can also set reminders for specific emails. This is useful for messages you need to act on later.

Using Quick Steps For Email Reminders

  1. Go to Home > Quick Steps > Create New.
  2. Name it “Remind Me Later”.
  3. Choose “Flag Message” and set a reminder.
  4. Add “Move to Folder” if desired.
  5. Finish the setup.

Now you can apply this Quick Step to any email. It flags the message and sets a reminder in one click.

Manual Email Reminder

You can also right-click an email, select “Follow Up”, and choose “Add Reminder”. This is slower but works for one-off messages.

Reminders In Outlook For Mac

Mac users have a slightly different interface. The core steps are similar.

Creating A Reminder On Mac

  1. Open Outlook for Mac and go to Calendar.
  2. Double-click a time to create a new event.
  3. Find the “Reminder” dropdown in the event window.

  2. Click the calendar icon.
  3. Click “New event”.
  4. Fill in details.
  5. Click “Reminder” and choose a time.
