Please note: In order to get your mailbox and mobility features working with your smartphone, you will need to set up your mailbox as a Microsoft Exchange mailbox.
This is so that the push content technology will work across your mailbox and smartphone.
Go to Settings on the iPhone.
Once in the settings menu click on the Mail, Contacts, Calendars button.
Then click Add Account...
Select the Microsoft Exchange option.
You will now need to fill in your Email Address, Username (which is your email address) and your Email address password.
You can also name the account in the Description box.
Once completed click on Next.
An error message may appear saying Cannot Verify Server Identity. If this message appears then click on Continue.
You will now need to enter the 123-reg email server details.
First you must decide whether you would like to use the POP3 or IMAP email protocol.
POP3 is the standard protocol for receiving email from a mail server and it allows you to download all of your emails to one location.
IMAP is best if you access your email from multiple locations, clients and devices as it doesn't require downloading of your email content. We recommend using IMAP settings on Windows Live because if anything were to happen to your computer or mobile device, you would still be able to access your emails.
To find out more about the POP3 and IMAP protocols, watch the following support video.
Once entered click on the Next button.
You will now see the details being verified and accepted. The next screen will show you what can be synced and give you the option to select them on or off.
Once completed click on the Save button.
That's it you are all set up and ready to start using 123-reg email on your mobile phone.
