Office 365 Outlook activity with a service principal

philipadc — Tue, 08 Jul 2025 17:13:46 GMT

Is it possible to use a service principal or registered application to send email using the Office 365 Outlook activity? If so, how? If not, what is the best practice for sending emails from pipelines without tying the sender to an specific developer's account?

Hi philipadc ,

Best practise is to use separate email id for sending email alerts. Please contact your IT team to get new Email Id created of your choice and use it further. You can request them to create in a email id of your choice like pipelinealert@xxx.com like that and it would be helpful to identify easily.

Hi philipadc,

you cannot use a service principal or registered application to send emails using the Office 365 Outlook activity in Fabric pipelines. The Outlook activity relies on delegated permissions, which means it requires a user to sign in interactively, and emails are sent on behalf of that user. It does not support application permissions, which are required for service principals.

Thanks,
