Description You open your Outlook app on your iPhone and it tries to update, but will not finish. On the bottom of the App all you see is Updating.   Issue: Outlook App not updating or stuck updating.   Solution: Force-quit and Re-open App Force-quitting and reopening the Outlook app is a quick way to fix the odd issue with the Outlook app not syncing. Just bring up the App switcher on the iOS device and swipe away the Outlook app card. Then, relaunch Outlook. In most cases, that should help get things moving again. Reset Email Account  If you continue to have sync issues in Outlook’s iOS app, it’s a good idea to reset the email account in question. Tap your profile portrait to the screen’s top-left to bring up the Outlook sidebar. Tap the Settings icon. Pick the email account under the Email Accounts section. Select Reset Account. Select OK to confirm. The Outlook app will quit automatically. Reopen it, and it should attempt to update your data. If you still encounter any issues, go ahead with the rest of the fixes. Restart the iOS Device If you continue to have issues syncing your email, calendars, or contacts, try restarting your iPhone before moving on with the rest of the fixes. Reinstall Outlook App If resetting your account didn’t help, try reinstalling Outlook.  Start by deleting the Outlook app from your or iPhone. Then, reboot your iOS device, reinstall from the Apple App Store, and set everything up from scratch. Reset Network Settings You can patch out broken or corrupt network configurations from interfering with Outlook by resetting the network settings on your iOS device. Open the Settings app on your iPhone. Select General.  Select Transfer or Reset Select Reset. Network Settings Reset. Tap Reset Network Settings to confirm. After the network settings reset, use cellular data or Wi-Fi (you must add Wi-Fi networks from scratch) and check if Outlook syncs your data properly.
