Samsung Galaxy S20 Calendar Not Syncing With Outlook: How to Fix

Pinterest LinkedIn Tumblr

The Samsung Calendar app on the Samsung Galaxy S20 is fully compatible with the Outlook app. This means that all your saved events and reminders should be synced with the Outlook app without any issues.

However, if you’re finding that your Samsung Calendar is not syncing with Outlook, the issue could be due to a misconfiguration or a glitch in the Calendar or Outlook app. Don’t worry, in this guide, I have included the necessary solutions to fix this problem.

Note: Solutions in this guide will work on any Samsung Galaxy S20 model (S20, S20 Plus, S20 Fe, and S20 Ultra models.)

Editor’s note: We created these instructions using a Samsung Galaxy S20 running Android 13. Depending on your device’s software version, some steps and menu positions may look slightly different.

Fix 01: Make Sure Outlook is Connected with Samsung Calendar

The first thing to verify is whether your Outlook account is connected to the Samsung Calendar app. This connection is important for the syncing process to work correctly. 

Here’s how you can check this:

  1. Open the “Calendar” app.

  1. Tap on the hamburger icon (three horizontal lines) at the top left corner of the screen.

  1. Scroll down and look for the “Calendars” section in the sidebar. Then check if your Outlook account is listed there.

If your Outlook account is not listed there, it means that Samsung Calendar is not connected with Outlook. In this case, you need to log out and log back into the Outlook app and add it manually to resolve the syncing issue.

To log out and log back into the Outlook app:

  1. Tap on your profile icon at the top left corner of the Outlook app.
  2. Select “Sign Out” from the dropdown menu.
  3. Confirm by tapping on “Sign Out” again.
  4. Restart the Outlook app and log back in using your credentials.

After logging back into the Outlook app, check if your Outlook account is now listed under “Calendar”. If it is not, follow the steps below to add the calendar manually.:

  1.  Open the Calendar app and go to “Manage calendars”.

  1. Tap on the “+” button.

  1. Select Outlook.
  2. Then select your account.

If the problem persists, proceed to the next solution.

Fix 02: Manually Sync Samsung Calendar

If your Outlook account is visible in the Samsung calendar’s sidebar, you can manually trigger the syncing process. This means you don’t have to wait for the apps to sync automatically.

Here’s how you can do it:

  1. Open the Samsung Calendar app and verify your Outlook account is in the sidebar
  2. Then tap on the “Sync Now” button to manually start the syncing process.

If the syncing starts successfully, your Samsung Calendar events and reminders should now be updated with the ones in your Outlook account.

Fix 03: Add a work or school Outlook account to the Samsung calendar

If you are using a work or school Outlook account, for the syncing process to work properly, it needs to be manually added as an “Exchange” account in your Samsung Calendar settings.

Follow these steps to add your Outlook account as an “Exchange” account:

  1. Open the Samsung Calendar app on your Samsung Galaxy S20.
  2. Tap on the menu icon at the top left corner of the screen.
  3. Tap on “Manage Calendars”.
  4. Tap on the “+” button.
  5. Select “Exchange” from the list of Outlook account types.
  6. Enter your work or school Outlook account details and follow the on-screen instructions to complete the setup.

Note: While the Samsung Calendar app can usually set up outside servers, sometimes it may fail. If this happens, contact your IT department for further assistance in setting up the account.

Fix 04: Clear Samsung Calendar App Cache

While the Samsung Calendar app cache is beneficial for speeding up processes, sometimes the cache can become outdated or corrupt, causing issues like the one you’re experiencing.

If this is the case, clearing the Samsung Calendar app’s cache will resolve the issue. Here are the steps to clear the cache:

  1. Go to Settings.
  2. Scroll down and tap on “Apps”.
  3. In the list of apps, find and tap on “Calendar”.

After clearing the cache, check to see if Samsung Calendar is now syncing with Outlook.

Fix 05: Update Samsung Calendar

If the Samsung Calendar app is out of date, the syncing issue you are experiencing could be due to a bug that has already been fixed in a newer version.

Therefore, check if there is any update available for the Samsung Calendar. If so, download and install the update to resolve the issue. 

Here’s how you can update your Samsung Calendar app:

  1. Open the “Galaxy Store” app.
  2. Tap on the menu icon in the top left corner of the screen.
  3. Select “Updates” from the dropdown menu.

  1. Look for the “Samsung Calendar” app in the list of available updates.
  2. If so, tap on the “Update” button next to the Samsung Calendar app to download and install the update.

Once the update is installed, restart your Samsung Galaxy S20 to make sure the changes take effect. After restarting, check if the Samsung Calendar is now syncing with Outlook.

Fix 06: Clear Samsung Calendar App Data

If none of the previous solutions have resolved the calendar not syncing issue with Outlook, you need to clear the calendar app’s data. 

Please note that this will remove all data stored in the calendar app. Therefore, I strongly recommend that you backup your calendar data before proceeding.

Here are the steps to clear the Samsung Calendar app data:

  1. Open the Settings app.
  2. Scroll down and tap on “Apps”.
  3. Tap on “Calendar”.
  4. Tap on “Storage”.
  5. Tap on “Clear Data”.
