Frequently Asked Questions

Why is my Outlook app not receiving new emails on Wi-Fi?

Background data restrictions or firewall settings on your specific Wi-Fi network might be blocking the synchronization. Check your device's data usage settings and ensure Outlook has permission to refresh in the background, or try switching to cellular data to see if the issue persists.

Does low battery mode affect Outlook synchronization?

Yes, 'Low Power Mode' on iOS or 'Battery Saver' on Android often restricts background app refresh. This prevents Outlook from fetching new emails automatically, requiring you to open the app manually to synchronize.

How do I force Outlook to sync manually on my phone?

You can force a manual synchronization by opening your Inbox within the Outlook app and swiping down from the top of the screen until you see the loading spinner, which indicates the app is refreshing.

Will removing my account from Outlook mobile delete my emails?

No, removing your email account from the mobile app only removes the locally cached data on your device. Your emails remain safely stored on your email provider's server and will reappear once you log back in.
