Two email addresses in Sender Field within FROM Field (Outlook 2016)

[lektrix]

Does this mean that the email was spoofed, if I happen to see two email addresses connected to just ONE sender in the FROM Field in Outlook 2016.......

i.e. Doe, Jane <#1 Jane.Doe@TESTxTEST.CA> <#2 abc.casdsadano@TESTxTEST.CA>

In this example #2 would be spoofing #1 correct???
