We share an SFDC instance with our team in the UK, who won't necessarily be moving forward with Marketo. As such, we'd like to make sure their SFDC records aren't synced into Marketo (syncing them into Marketo would mean we're bumped into the next pricing tier).
I found this thread about having Support create a "Hide from Marketo" field and suppressing the leads: Re: Is it possible to "hide" leads that are in Salesforce from Marketo?
But I also came across a training (whose link no longer works) called "Hide Records from SFDC with the Sync Profile". Has anyone done this? How involved was it and have you run into any problems? Also, if anyone could point me to some printable instructions for our SFDC admins, that would be swell
