I have clients who use Rackspace for their professional email hosting (i.e. firstname.lastname@example.org). So, when I came across a helpful, online support site for Rackspace Email, Hosted Exchange and Office 365*, I wanted to share. From troubleshooting a problem to instructions on how to setup your email on different devices, just go to https://emailhelp.rackspace.com and login with your email and password.
*Help for Office 365 at emailhelp.rackspace.com is only for those organizations that signed up for Office 365 via Rackspace.
I have experience with most of the major email hosting services out there including Microsoft Office 365, G Suite by Google, Rackspace Email, and FastMail. Get in touch with me and I can help you pick the right email hosting for your organization. Once you decide which service is a good fit, I can even help with getting everything set up.
