Hello guys, I am not sure if I can define the app to use our group outlook email which will replace the default from User().Email to specific email.
Hi @nagestiada
You can use the function Office365Outlook.SharedMailboxSendEmailV2() instead.
Use your group email address and make sure you are a member of that group email address.
See here for more info about creating a group in Microsoft 365.
