SummaryHow to add a 'mailto:' link extension to one of your emails in Office 365 workflows.
SolutionUse the Rich Text option to add the link, or directly embed the reference into the email's HTML. For example:
<a href="mailto:email@example.com?subject=testing out mailto&body=Just testing">This is an example</a>
This would create a link that says "This is an example" that when clicked would open an email message to "firstname.lastname@example.org" with the subject line of "testing out mailto" and a body pre-populated with "Just testing".
