How does this have value? Is any and every sentence in an e-mail considered 'fact' and thus to be fed into the AI?

90% of e-mails and Teams communications are inane. Polite banter, "thanks for taking care of that, I appreciate it" "please route the forms to Janet this week because Bill is on vacation" "unit will be un available until the parts come in" . I can't see the intrinsic fact value of this kind of communication without screening it. And after screening, the gold nuggets would be minimal.
