Hi @Anonymous ,
As @gabibalaban mentioned, when sending email using the Outlook365 connector in PowerApps, after the normal details you can add the Cc in as an optional parameter.
But @gabibalaban , per my test, CC did not work for me, only Cc works on my side. Not sure if this is related to region.
@Anonymous ,since you didn’t provide the exact email, we can only give you the example about how to use this function, you must need to replace to the email you want to send to inside {Cc: } .
So I would suggest you try formula like below(replace "author.email@XXX.com" to the author' email, must use double quote😞
Office365Outlook.SendEmailV2(FinanceApprovalEmail.Text, "Please check detail","READ ALL <a
href='https://apps.powerapps.com/play/a2e877a8-0737-4da6-bb5d-dddacac25ab4?tenantId=4c8e3abd-a4a8-436b-a34... varMasterID & "'>Link</a>",{Cc:"author.email@XXX.com"})
See my result:


Best regards,
Allen
