Missing inbox

If you have a missing inbox in Outlook (or another missing folder), this could be that it is set to hidden.

There is no official way to change this. It's a known bug with Exchange 2003/2007.

Firstly, try opening Outlook via Start > Run with the following command:

outlook.exe /resetfolders

If this does not work, you will need the following: https://mfcmapi.com/

  • Open Outlook (has to be 32bit as there is no 64bit version of this software)
  • Open MFCMAPI
  • Select the account
  • Select the store that the folder is in
  • Navigate to the folder that has vanished
  • On the right hand pane, you should see an option for PR_ATTR_HIDDEN
  • Right click this and choose Edit Property
  • Untick the checkbox
  • Close MFCMAPI
  • Restart Outlook and you should see the folder
