[SalesForce] Email to Case (on demand) forwarding via Outlook rules

I am having trouble to forward e-mails coming into my Outlook Exchange Inbox into the Salesforce environment (creating a case).
I have managed to do this in Gmail, since it's fairly easy to do so. Just followed the link:
https://help.salesforce.com/articleView?siteLang=en_us&id=000170989&type=1

It looks like there is no proper answer on the internet for using this function with Outlook 2013, as I can't find any specific documentation on how to do this in combination with Salesforce.

Are there any other experiences about this?

I would love to hear.

EDIT: I'll break it down for more understanding:

I want exactly the following:
-Forward a copy of incoming mail to "E2C – Salesforce Email Services Address" AND keep Gmail's copy in the inbox. + Enabling IMAP.

The method above worked for my E2C-on-demand mechanism in Salesforce: All emails i receive on that Gmail, would become a case IF there is no REF ID involved. However, when there IS a REF ID involved: the sent (inbound) emails would be logged under the right case.

As for Outlook 2013… It seems to be IMPOSSIBLE to re-produce the same method within the "Manage Rules & Alerts" options in Outlook.
As I have 1. my personal inbox email, 2. a functional mailbox. I want the ruling to be applied on only the functional mailbox. Once i enable the created ruling for my entire Microsoft Exchange account (meaning personal + functional mailboxes, which is actually something i don't want) it will produce an error anyway.

Ruling: Apply this rule after the message arrives
on this computer only
forward it to "E2C – Salesforce Email Services Address"
and move a copy to the x folder

After this i realized i should use redirect instead of forwarding:

Apply this rule after the message arrives
redirect it to "E2C – Salesforce Email Services Address"

Bottom line, both methods don't work.

Also there is something extra which is not gonna work out for us as well:
"The rule will only run when you check your email in Outlook. If Outlook isn't running, this rule won't work for email you check online or from another device."
