    Hello Prajakta Patil,

    The standard Microsoft 365 Outlook and SharePoint connectors in Power Automate require a user-based connection. The Office 365 Outlook connector does not currently support Service Principal-based authentication, while the standard SharePoint connector does not provide Service Principal as an available connection authentication option.

    If you specifically need to connect to SharePoint by using a Service Principal, I found the following Power Platform Community suggestion for your reference: Power Automate SharePoint Connection via Service Principal

    The suggested alternative is to use HTTP actions instead of the standard SharePoint connector. This is a more advanced approach and may require additional configuration and licensing.

    Since the implementation depends on your specific flow design and authentication requirements, I recommend posting the detailed scenario in the Power Platform Community if you require further technical guidance. Power Platform specialists and community experts may be able to provide more targeted recommendations for your use case.

    I hope this information helps clarify the available options.

    Kind regards,
