Outlook not syncing on Android? Here’s what to do

Microsofts Android suite gained a lot of popularity as the Redmond giant invest more in the development of apps like Microsoft Outlook. And the app is usually good, for some probably better than Google’s Gmail. However, some users are bothered by quite a debilitating error, as Outlook for Android is not syncing.

Learn how to fix this with the instructions below.

How do I sync my Android with Outlook?

This is usually done automatically as soon as you add and configure your account in Outlook. However, as we are obviously looking at an error, it is suggested to check the connection, reset your account or, eventually, rollback the app to an older bug-less version.

Solution 1 – Check the connection

The first thing to do is to ensure that your device is connected to a stable Wi-Fi. Inspect the connection and see whether any other app suffers from network issues. If the problem is isolated to Outlook, then you can move to another step.

On the other hand, if you have connectivity issues in general, try these steps:

  • Reboot your phone/tablet and your wireless router.
  • Enable Airplane mode for a couple of minutes. Disable it, connect to a network, and try syncing emails again.
  • Reset Network Settings.
  • Check out our articles about Wi-Fi and data issues on Android for more solutions.

Solution 2 – Reset the account

The Outlook app offers a built-in reset option if emails are not syncing. You can find it in the individual account settings within the app. Once you reset the account, it will restart the syncing process and, hopefully, fix the problem for good.

Follow these steps to reset Outlook account:

  1. Open Outlook.
  2. Tap on the hamburger menu and then on the cog-like Settings icon.
  3. Open the Microsoft account that won’t sync.
  4. Scroll down and tap Reset Account.outlook not syncing android

Solution 3 – Remove and add the account again

Moving forward. Of course, in case you still weren’t able to resolve the sync issue, you can try and remove the account. Along with that, you can navigate to Outlook in a web browser and remove the Android device from the Sync list.

In order to do so, follow the steps from the previous solution just, instead of Reset, tap Delete Account. Add the account again afterward and look for improvements.

Solution 4 – Reinstall Outlook

If the previous steps weren’t of any help, let’s reinstall the app and give it another go. Usually, Microsoft tends to its Play Store apps but there might be a bug at the current version. If that’s indeed the case, the reinstallation should fix it for good.

Follow these steps to reinstall Outlook on Android:

  1. Open the Play Store.
  2. Search for Outlook and expand the Microsoft Outlook: Organize Your Email & Calendar app.
  3. Tap Uninstall and restart your device.outlook not syncing android
  4. Now, open any browser, navigate here, and sign in with the affected Outlook/Hotmail account.
  5. Under the Mobile device in the left pane, locate your device, highlight it and click on the minus sign (-) to delete it.
  6. After that, just install Outlook again, add your account, and look for improvements.

Solution 5 – Download an older APK version of Outlook

Finally, if you are still stuck with Outlook not syncing, you can rollback the app by installing an APK from APK Mirror (or any other APK aggregate of your choice). There’s definitely something flawed with the current version so, by installing an older version, Outlook should be able to sync emails successfully.

Here’s how to download and install an Outlook APK on your phone or tablet:

  1. Uninstall Microsoft Outlook as explained above.
  2. Navigate to APK Mirror, here, or any other APK hub online.
  3. Download an older APK version but not older than two months.
  4. Grant permission to install apps from untrusted sources.
  5. Install the APK and give it a go.

I was able to fix my issue but checking the “All Mail” – “Show in IMAP” under labels.

where do you find this in the app?? I can’t see an option for this…

Method 2 is no longer applicable. Although the account settings screen says “Sync issues? Try resetting you account”, there is no Reset button anymore, just the Delete Account button.

I downloaded “Email – Lightning Fast & Secure Email” app by Edison Software… set it up manually and it worked.

I think I’ve found the problem. Try this : Go to Battery optimization, and DISABLE the optimization for all “Outlook” and “Authenticator” (if you have it).
As soon as I did this, all emails synced again without doind any reset or reboot.

THANK YOU, Christophe! I have been looking everywhere for a solution to this, and found many that made no difference at all. Eventually I came across your ‘battery optimisation’, and solution worked brilliantly!
