@Vineeta Bedi Thanks for reaching out. We have 2 connectors outlook.com and office 365 outlook which supports "send an email V2" action.
If you are using an account that belongs to an organization, you won't be able to use the Outlook.com connector to send emails. Instead, you can use the Office 365 Outlook connector to send emails.
do try and let me know incase of further queries, I would be happy to assist you.
