Hi guys, I have tried to find the answer everywhere but with no luck. Is it possible to connect 2 Marketo instances to 1 Salesforce? If so, is it possible to do it natively or do we need to use 3rd party tools/API? Thank you!

In our org we're about to launch a second Marketo org connected to a single Salesforce org natively, so despite what you have seen above, we have been advised this is possible and are on track to do it. However, there are drawbacks - like you can only have Marketo MSI associated with a single Salesforce org.
