We have a new interWays connector for use with Outlook and Windows 8. It can be found in our Downloads section.
We recommend using Outlook (2003, 2007, 2010 or 2013), since it offers better and more functionality than the Windows 8 integrated clients.
To set up the integrated Windows 8 mail, contacts and calendars client:
Open Mail App
Create new account
Account type: Exchange ActiveSync EAS
Click on "Show more options"
Enter server address: ssl.interways.de
Domain: leave empyty
Username: your interWaysMAIL Email address
PassworD: your interWaysMAIL password
