Dear James Ferguson
Thank you for reaching out to the Microsoft Q&A Community. I understand you are having problems with emails saved to folders not appearing in Outlook for iOS. I am happy to assist you. Please kindly follow these steps :
- Update Outlook app and iOS
- Ensure the Outlook app and iOS are updated to the latest versions. Outdated versions can cause sync issues.
- Reset Outlook app cache
- In the Outlook app, go to Settings > Help & Feedback > Troubleshooting > Reset Account.
- This clears cached data and forces a full resync of folders.
- Remove and re-add the account in Outlook app
- Go to Settings > Accounts, select the account, and remove it.
- Add the account again to refresh sync settings.
- Verify folder sync settings
- In Outlook app, tap Settings > Accounts > Your Account, ensure all folders are selected for sync.
- Check server-side folder visibility
- Sign in to Outlook on the web (https://outlook.com) and confirm emails are present in folders.
- If they appear online but not in the app, the issue is local sync and will be resolved by steps above.
- If using iOS Mail app instead of Outlook app
- Go to Settings > Mail > Accounts > Your Outlook Account > Mail Days to Sync, set to No Limit.
- Remove and re-add the account if folders still appear empty.
