Today a customer opened a ticket via e-mail, which 99% of our customers prefer to the portal. I created a public comment that I would engage this afternoon, which should have sent her an e-mail. Shortly thereafter, she forwarded a standard portal invitation e-mail back to us and asked if we sent it.
The e-mail looks legitimate, the links appear to be secure. I looked in the customer notification logs but I don't really see a log for outbound portal invitations. How could an invite be sent to someone who has been opening tickets for many months?
