Through the Service Desk project, we invited (added) a customer to a Service Desk organization. The received an automated invitation email, with a link pointing to the Service Desk Portal, in order for the customer to create initiate his name/surname and his password.
The customer did not immediately pressed the portal link from his email, but instead he waited for three days in order to do so.
When he pressed the link, he was presented with a page saying: "Token is either expired or not valid" and a button saying "Log in here".
So, the customer has no practical way to inform the our Service Desk agents about this incident.
How can we overcome this?
