I don’t see a reference number on the emails. The email correspondence is with “Marko K” and “Tickera Team” and begins on Sat, Jun 12, 2021 with the last email in the chain on “Fri, Jun 18, 2021.” There appear to be 5 emails in the chain.
Same here. On the “From” field I get, ” Invalid mailbox syntax is used.” and on the “Subject” field I get, “(configuration error) There is a possible empty field.”
