Set up Business Email on Outlook and mobile

Applies to: Business Email services on Odinson using CrossBox and Plesk-managed mailboxes.

This is the right path when the mailbox already exists and you want it in Outlook, Apple Mail, iPhone, Android, or another IMAP app.

Before you start

• Make sure the mailbox already exists in Plesk.
• Keep the full email address and the mailbox password ready.

Steps on OneNet Servers

1. Use the full email address as the username.
2. Use odinson.onenetservers.com on port 993 for IMAP with SSL.
3. Use odinson.onenetservers.com on port 465 with SSL or port 587 with STARTTLS for SMTP.
4. Turn on SMTP authentication and use the same full email address and password there as well.
5. If the app still fails, test the same mailbox in CrossBox webmail before you keep changing settings.

What you should see next

• The account should save cleanly without repeated password prompts.
• You should be able to send a message to yourself and receive it back.

Common issues

• Using only the mailbox prefix instead of the full email address breaks many setups.
• An app can keep an old saved password even after you reset the mailbox password.

When to contact support: Contact support if the same credentials fail in both CrossBox and the mail app after you confirm the DNS still points to Odinson.
