Dell 3115cn Fax to Email

I am trying to assist a user who claims they were able to have faxes forwarded to their email from the Dell 3115cn MFP. I have looked through the user manual and can't find support for such a feature. The only previous topic I could find for this model is here https://www.dell.com/community/Printers/Multifunction-3115cn-Email-incoming-faxes/m-p/2221812#M27565 I would take this as my answer but it is 12 years old and the user is adamant that it was setup before. They are added to the address book, but I simply cannot find an option to forward to email. Any assistance would be greatly appreciated.
