- Product
- Microsoft Outlook for iOS
- Device & OS
- iOS
- Scenario
- Reconfiguring an email account in the Outlook mobile app and noticing missing data.
- Observed behavior
- Inbox subfolders are missing on the iOS app despite remaining fully visible and accessible on the Windows desktop version of Outlook.
Before making changes on your mobile device, log in to Outlook on the web or your desktop application to verify that the missing subfolders still exist securely on the email server.
Remove and Re-add Your Email Account to Force Synchronization
The most effective way to restore missing folders after an account setup glitch is to completely remove and re-add the account, which forces the app to freshly download the folder hierarchy from the server.
This process will clear the local app cache and initiate a fresh connection to your email provider.
Launch the Outlook app on your iOS device and tap your profile icon in the top left corner. Then, tap the gear icon at the bottom left to open the Settings menu.
Select the affected email account under 'Mail Accounts' and scroll down to tap 'Delete Account'.
Swipe up from the bottom of your screen to close the Outlook app entirely, then reopen it.
Go back to Settings, select 'Add Mail Account', and sign in with your correct email credentials. Allow a few minutes for the synchronization to complete and check your folder list.
Update the App and Contact Support
If re-adding the account does not resolve the sync issue, the app might be outdated or require advanced troubleshooting from Microsoft or your IT admin.

Frequently Asked Questions
Why do my Outlook folders show on my desktop but not on my iPhone?
This typically happens due to a synchronization glitch in the Outlook mobile app, an outdated app version, or an interrupted connection that prevented the mobile app from fully downloading the folder hierarchy from the Exchange or IMAP server.
Will removing my email account from Outlook iOS delete my emails permanently?
No, deleting the account from the Outlook mobile app only removes the cached local data on your phone. Your emails and folders remain safely stored on the email server and will reappear once you re-add the account.
How long does it take for subfolders to sync in Outlook for iOS?
Once you add an account, initial synchronization can take anywhere from a few seconds to an hour, depending on your internet connection speed and the overall size of your mailbox.
