Use the incoming and outgoing server settings shown for the active OX service.
Applies to: OX App Suite
OX App Suite combines hosted email with browser-based productivity features. Exact capabilities depend on the purchased plan, so confirm the active subscription before troubleshooting a missing feature.
Before you start
- Confirm the active product or addon and the domain or user it protects.
- Record the current settings before changing them.
Step-by-step
- Create the mailbox first.
- Open the device mail account settings.
- Enter the full email address, password and supplied IMAP/SMTP settings.
- Require encrypted connections and SMTP authentication.
- Send and receive a test message.
Confirm the result
- The service dashboard shows the intended setting or activation state after reload.
- A live test from a separate session or device confirms that the customer-facing service works as expected.
Common problems
| Symptom | Likely cause | What to do |
|---|---|---|
| Receiving works but sending fails. | SMTP authentication, the outgoing hostname, port or encryption mode is incorrect. | Use the full email address as the username and the exact secure SMTP settings supplied for the hosting service; do not use unauthenticated port 25 from a mail client. |
| The same mailbox works in webmail but not on one device. | The mailbox is healthy and the fault is in the device profile, saved password, certificate warning or local network. | Remove only the affected account profile after recording settings, then add it again with IMAP so server mail is not deleted. |
Important notes
- Mailbox storage is part of the hosting plan's total storage allowance. Removing a device profile does not increase server quota, and POP settings can remove messages from the server.
When to contact Tudor Internet
Open a ticket through the Customer Portal when the checks above do not resolve the issue, when an action is unavailable for your service, or when continuing could risk data loss or service interruption. Include the following so the request can be investigated efficiently:
- The addon service and protected domain or user
- The plan or licence level
- The time the issue started and exact message
- Screenshots with credentials, tokens and personal data removed
Do not send passwords, private keys, full payment-card details, one-time authentication codes or unredacted identity documents in an ordinary support reply.
