Forward From Office 365 Outlook Web Access (OWA)
This article will walk you through forwarding email from Outlook Web Access on Office 365, also known as OWA, to your Help Scout Mailbox.
First things first: Make sure you have followed the first steps in Connect Your Custom Address and you have your Help Scout Mailbox Address ready.
Log in to your Office 365 Outlook Web Access as your custom email address. You may be able to log in at https://outlook.office365.com. If you're not able to log in there, check with your email administrator to find out the address for your OWA login page.
Click on the gear icon in the upper right-hand corner, then View all Outlook settings at the bottom of that menu.
Choose Mail, then Forwarding. Click Enable forwarding and paste in your Help Scout email address. We recommend also checking Keep a copy of forwarded messages as an archive. Click Save at the bottom of this screen then close the menu by clicking the x in the top right corner.
That will do it — head back into Help Scout to see your emails in your mailbox! Next steps: Set up SPF and DKIM to allow Help Scout servers to send email on your behalf, or set up Custom SMTP to have your email sent from Office 365's servers.
