Error "The program cannot access the file because it is being used by another process"

This error message is typically displayed when there is an issue with the Outlook Plugin configuration file. To resolve, take the steps outlined below to generate a clean configuration file:

1. Close the Outlook application if running.
2. Double check the Windows Task Manager to ensure all Outlook.exe processes are terminated.
3. Remove the SendSafely folder from the user's profile. To do this, browse to the “%AppData%” folder in Windows Explorer, and delete the SendSafely folder.
4. Re-launch Outlook. This will reset the plugin preferences file, and a new clean configuration file will be generated when Outlook is re-launched.

NOTE: The SendSafely plug-in will prompt you to re-configure your credentials after re-launching Outlook.
