Send mails on behalf of with Office 365 Integration in Designer

Hi all,

we're looking for a way to send mails “on behalf of” with CoreSuite Designer Mailer and Office 365. We need to send the mails under common mail address like accounting@… oder orderconfirmation@…  or noreply@… so that customers don't reply to individual persons. Is there any possibility?

In the past we used the “From Address” field which becomes now greyed out when changing the sending method to 10 - Office 365 Prompt. Sending is at the moment only possible in name and email address of the logged in user.

We also don't want that the users have to login to common used mailboxes for seucrity reason, traceability who actually sent the mail and also to not break active Single Sign On login to SAP.

Thanks for any idea or help
André
