Outlook - Disable copying to the Sent folder

These settings are necessary, if your mailbox has been configured (on the server) to automatically save copies of sent messages to the Sent folder on the server.

Do not use the settings below, if the above setting is not configured, as sent messages will not be saved.

If you're unsure whether your mailbox is configured for automatically copying to your Sent folder, please either ask the help desk to clarify, or configure the below and send a test. If the test shows up in your Sent folder, then its enabled on the server. If not, it isn't and you should reverse the settings, until we've configured it for you on the server.
