Does anyone know a way to set "TRANSACTION EMAIL ATTACHMENT FORMAT" to PDF for the entire organization? Having it a user preference isnt really where that decision lives in our organization.

Nope. It lives in the user preference, not general. Classic pain for years. Have it as part of user onboarding.

Thanks. I thought so. I was hoping there was something I could share as our new CRO is losing his mind. I love NS but this is probably the straw that breaks the camels back on Org Controls.

I believe you can force this in the Vendor and Customer records. Under the Preferences subtab, change it to PDF instead of User Preference (manually/through CSV). You can use a workflow so that it will default to PDF when creating new Vendors and Customers.

I'll check that out. Our consultants may have hid that field (dont know why) but I will try. Thanks @Luis!
