Ok, so I've set up a Collaborative Inbox on Google Groups for Business. It looks good so far, but one thing I can't seem to figure out:
I would like to use it for email@example.com, and one of the biggest use cases would be to start a thread by writing email to a potential candidate. I tried to send email from Gmail, using "send as", to an external address - this doesn't open a thread in the group. Then I sent an email to an external address CCing of BCCing firstname.lastname@example.org - this opens a new thread, but the message comes from career@ and shows no sign of the external email, which seems obvious.
Within the group, I don't seem to be able to start a new thread that initially goes to an external email.
Is there a way to do this use case with Google Groups for Business / Collaborative Inbox?
