does Eikon messenger add messege id of its own when adding a contact and sends the email invitation? if yes can you brief it by example? because the client IT blocks this email for some reason.
Could you please clarify if the question relate to the "Eikon Messenger Application" or "Messenger Bot API"? If the client encounters the issue with the Eikon Messenger Application or Eikon Messenger account, I suggest the client contact the Helpdesk support team via https://my.refinitiv.com/ web site.
