Troubleshooting in Microsoft Outlook

I opened the Mobile Locker sidebar but it is blank

Is your computer connected to the internet? If so, right-click in the blank area, then click Reload.


Common Outlook Integration Errors

Sometimes Outlook gets caught in a weird funk and causes some errors.

  • Not running inside Outlook Error - This error occurs when the application cannot detect or connect to Microsoft Outlook.

  • System.ArgumentOutOfRangeException Error - This technical error occurs when the application receives data that falls outside the expected range of valid values.

Please try these steps:

  • Close Outlook completely (all windows, not just the current one)
  • Open Outlook again
  • Click New mail
  • Enter the recipient's email address
  • Open the Mobile Locker plugin
  • Select a file
  • If it still happens, reboot your computer and try again.
