    Hi Carol Smith

    Sorry you're having trouble with this. From your description, I understand that your Classic Outlook email has stopped syncing with Outlook on your Android phone, even though it was working before. I know how inconvenient this is.

    I see that Q&A Assist has already provided several troubleshooting steps for Outlook on Android. Before we continue, could you please let me know:

    • Have you already tried the steps suggested by Q&A Assist on your Android device? If yes, what happened after that?
    • Whether your account is an Outlook.com/Hotmail/Live account or another email provider?

    In the meantime, please try these additional steps:

    1, Check whether the mailbox is syncing outside the Android app

    Sign in to the same email account in Outlook on the web using a browser > send yourself a test email. If webmail is up to date but Android is not, then issue is isolated to the mobile app or device sync

    2, On your phone, disable battery optimization

    • Go to Settings > Apps > Outlook > Battery
    • Disable battery optimization for Outlook

    3, Allow background data for Outlook

    • Go to Settings > Apps > Outlook
    • Tap Mobile data
    • Enable the toggles next to Allow background data usage and Allow data usage while Data saver is on

    4, Clear cache

    • Go to Settings > Apps > Outlook
    • Tap on Storage and then select Clear Cache

    5, Reinstall the app

    • Uninstall the Outlook app from your device
    • Restart your phone
    • Reinstall the Outlook app from the Google Play Store

    Please feel free to let me know how it goes after trying those steps. Thank you for your time and understanding.

    Follow these steps in order on the Android phone and in Outlook to fix classic Outlook email not syncing:

    1. Reset the account in Outlook for Android
      1. Open the Outlook app on the Android phone.
      2. Go to Settings.
      3. Tap the email account that is not syncing.
      4. Tap Reset Account.
      5. Wait a minute, then check if new mail, calendar, and contacts sync.
    2. Remove and re-add the account in Outlook for Android If resetting does not help:
      1. In Outlook for Android, go to Settings.
      2. Tap the account that is not syncing.
      3. Tap Delete Account > Delete From This Device.
      4. Add the account again using the normal setup flow for Outlook for Android.
      5. If prompted to set up the account as IMAP and calendar/contacts are needed, contact the email provider or admin for the correct Exchange/modern settings, because IMAP cannot sync calendar and contacts.
    3. Re-establish the device partnership from the mailbox side If email still does not sync correctly, remove the phone’s partnership from the mailbox and let it reconnect:
      1. Sign in to Outlook.com or Outlook on the web for the mailbox.
      2. Go to Settings > General > Mobile devices (or Mobile devices under the appropriate section, depending on Outlook version).
      3. Select the Android phone from the list.
      4. Select Remove (or the delete icon) to delete the device partnership.
      5. Select Save if prompted.
      6. On the Android phone, power it off completely.
      7. Turn the phone back on and open Outlook so it can re-sync with the mailbox.
    4. If calendar/contacts still do not sync
      1. On a Windows PC, set up the same email account in classic Outlook using the Exchange protocol.
      2. Verify the connection, send a test email, and create a test calendar event.
      3. Close Outlook on the PC and restart the PC.
      4. Open Outlook again and confirm the test event appears in the calendar.
      5. On the Android phone, open Outlook and check if the same event and recent mail now sync.
      6. If the event still does not show, go to Settings in the Outlook app on Android and restart the app.

    If none of these steps resolve the issue, use the in-app support in Outlook for Android (Settings > Help & Feedback > Contact Support) for further investigation of the specific account and device.
