Folder missing in outlook after import
Outlook 2013/2016 - How to Set View for All Folders
Apply Current View to Other Mail Folders
1. In Outlook, click the View tab.
2. In the View menu, click the Change View drop-down menu.
Reset All Views to Default
If the view is still not applied to a desired folder, the individual folder was most likely set to a custom view previously. To correct this action, reset the view settings of all Outlook folders back to the default setting by launching Outlook with the cleanviews switch.
1. Ensure Outlook is closed.
2. From the Run command (Windows Key + R), type outlook.exe /cleanviews and click OK.
