I am currently using get outlook mail message activity and I am facing the same issue where the mail.from.address is returning a null value. this problem only occurs for a particular sender. Does anyone have any idea about the cause of this issue?
There does not seem to be any extraordinary about the email address of the sender. In fact this, when studio is run from another machine, the sender’s email.sender or email.from.address works normally. It is only within the production machine that this issue is encountered (and for this sender).
