What I have come up with is this. I have users who go to the contact and try to send it as a business card which is a .vcf. If the user tries to send out a contact from her company they get a message stating that they do not have rights to send on behalf of the sender. I tried bringing the From field into the email and had the user put their email address in there but it did not fix the issue they get the same error message stating they do not have rights to send on behalf. If they send a contact which they created or is a contact that is not internal to the company it goes through without an issue.
Does anyone have an Idea as to what would be causing this?
