Trouble getting outlook to sync

Follow these steps on the Galaxy S26 Ultra to troubleshoot Outlook sync issues:

1. Reset the account in Outlook for Android
   1. Open the Outlook app.
   2. Go to Settings.
   3. Tap the email account that is not syncing.
   4. Tap Reset Account.
   5. Wait a minute, then check if mail, calendar, and contacts sync.
2. Remove and re-add the account
   1. In Settings in Outlook, tap the account that is not syncing.
   2. Tap Delete Account > Delete From This Device.
   3. Add the account again using the normal add-account flow in Outlook for Android.
   4. If prompted to set up the account as IMAP or POP, be aware these can only sync email, not calendar or contacts. For calendar/contacts, the provider must support Microsoft Exchange ActiveSync.
3. Check for general Outlook-for-Android setup/sync issues If setup or sync still fails, use the targeted help:
   • For general setup/sync problems, see Troubleshoot email setup on mobile from the Outlook for Android help.
   • If this is the first time setting up the account on the phone and calendar/contacts will not sync, follow Sync calendar with my phone or tablet guidance.
4. If using Outlook.com or Microsoft 365
   • If the account is Outlook.com (hotmail.com, live.com, msn.com, etc.), first check the Outlook.com service status.
   • If the account was syncing before and stopped only after moving to the new phone, and it is an Outlook.com account, follow Fix Outlook.com email sync issues.
5. If using a Microsoft 365 work or school account on Android Some Android models have issues when Authenticator or Company Portal is installed:
   1. Turn off power-saving mode or change its settings so apps can launch other apps.
   2. Disable power optimization for Authenticator/Company Portal so they can run in the background.
   3. Open Authenticator or Company Portal first, then open Outlook and try syncing again.
6. If still not syncing
   • On a PC, set up the same email account in Outlook using the Exchange protocol, send a test email, and create a test calendar event.
   • Close Outlook on the PC, restart the PC, reopen Outlook, and confirm the test event appears.
   • Then check Outlook on the phone again. If the event still does not appear, go to Settings in the Outlook app on the phone and restart the app.

If none of these steps resolve the issue, use in-app support: in Outlook for Android, go to Settings and use the Contact Support option to chat with support agents.
