We would strongly recommend using the automatic setup detailed in our 'Setup Outlook ~ Desktops ~ Windows' article. In the event where the automatic setup fails, be sure to double check for Autodiscover DNS records, and check that this can be reached from the failing machine.
Manual setup should be done as a last resort and may cause issues with the stability of Outlook in the long term.
To manually configure the profile (note: this will only work for Outlook versions prior to 2016):
- Repeat the steps under "To create an Outlook profile".
- Select "Manual setup or additional server types", and click "Next".
- Select "Microsoft Exchange Server or compatible service", and click "Next".
- In the "Server" box, type "owa.onenet.co.nz". In the "User Name" box, type the email address. Click "More Settings…".
- Select the "Connection" tab. Tick "Connect to Microsoft Exchange using HTTP". Click "Exchange Proxy Settings…"
- Type "owa.onenet.co.nz" and "msstd:owa.onenet.co.nz" the boxes. Tick both "On fast networks…" and "On slow networks…". Under "Proxy authentication settings", select "Basic Authentication". Click "OK".
- Enter your OneNet credentials. Click "OK".
- Click "Finish".
If the above does not work for Outlook 2010, it is highly recommended to upgrade Outlook to 2013 or 2016. Our back-end Exchange infrastructure is constantly updated for security fixes and additional features. It is recommended that Outlook (the client side) is updated to match the same version on the back-end. For example, use Outlook 2016 to match Exchange 2016. As of this writing, Outlook 2010 is 8 years old and will likely have more compatibility issues compared to Outlook 2013 and 2016.
