I'm in California and I'm wondering if there are ways that I can potentially be violating an NDA with out knowing that I am. For instance, if I'm disclosing confidential info in an email to a colleague that has signed the same NDA, but the fact that I'm using an email service, has that exposed us to violation of the NDA? In other words, I know the obvious ways that I can violate an NDA, but are there other ways that one can violate an NDA inadvertently.
