How do I set up a mail account in for example Outlook?

You can set up your email account in a client on your computer or a mobile device. Examples of clients are Outlook or Mac Mail. Before you can set it up, you first need to create an email account in the control panel.

What settings should I use?

Depending on the client you are using, the setup will be different, but normally you need the following settings.

Username: your complete email address
Password: the one you chose when you created your account

Incoming server: imap.one.com
Incoming server port: 993 + SSL

Outgoing server: send.one.com
Outgoing port: 587 + TLS/SSL/STARTTLS (or 465 + SSL/TLS)
Outgoing server authentication: username and password, same as the incoming server

We recommend using IMAP to set up your email account because it syncs your emails across all your devices and Webmail. Unlike POP, which downloads your emails and removes them from the server and Webmail.

If you really want to use POP, you need these settings for the incoming server: pop.one.com - port 995 - SSL.

What is the difference between POP and IMAP?

If you want to set up your account on a mobile device, you can also consider using Mobile Sync. The advantage of Mobile Sync is that it also syncs your calendar and contacts. You can activate a free trial of Mobile Sync from Webmail.
