Get your email working on every device
Server settings explained in plain language, step-by-step setup for Outlook, iPhone and Android, and fixes for the problems that actually come up.
What are you setting up?
Pick your device and follow the steps. Every guide uses the same handful of settings — they just live in different places.
Microsoft Outlook
Windows and Mac, including manual setup when auto-discovery guesses wrongly.
Open guideiPhone & Android
Getting mail working on your phone with sensible sync and battery settings.
Open guideAny other mail app
The universal settings every mail client asks for, and what each one does.
Open guideSpam & security
Train your filter, spot phishing and keep your mailbox safe.
Open guideThe six values every mail app asks for
Have these to hand and setup takes two minutes on any device. Your exact server names are in your welcome email — the rest is standard.
They’re in your welcome email and available from our support team. Values differ depending on which mail platform your account sits on, so please use the ones we gave you rather than guessing.
IMAP or POP3?
Choose IMAP unless you have a specific reason not to. It keeps your mail on the server, so every device sees the same inbox.
| IMAP — recommended | POP3 | |
|---|---|---|
| Where mail lives | On the server | Downloaded to one device |
| Multiple devices | All stay in sync | Mail lands on whichever checks first |
| Read & folder status | Shared everywhere | Local to one device |
| If a device is lost | Nothing lost | That device’s mail is gone |
“I can receive but I can’t send”
By far the most common email problem, and it is almost always one of these four.
- Outgoing authentication is switched off. In your outgoing server settings, enable “My outgoing server requires authentication” and set it to use the same credentials as incoming mail. This is the single most missed setting.
- The wrong SMTP port. Try 587 with STARTTLS, or 465 with SSL/TLS. Some mobile networks block port 25 entirely — which is why mail may send on Wi-Fi but not on mobile data.
- The message is too large. Most servers reject attachments above roughly 20 MB. Use a file-sharing link instead.
- The outbox is jammed. One stuck oversized message blocks everything behind it. Open your Outbox, delete it, try again.
Password resets
- Requesting a reset. Contact our support team from the registered account holder’s details. We verify identity before resetting any mailbox password.
- Update every device afterwards. Phone, tablet, laptop and desktop all store the old password, and devices retrying with an outdated one can trigger a temporary lockout.
- Use a strong, unique password of at least 12 characters, not reused from another service.
Other quick fixes
| Symptom | Usual cause |
|---|---|
| Password rejected repeatedly | Username needs to be the full email address, or a trailing space was pasted in |
| Certificate warning | Server name typed slightly wrong, or encryption type doesn’t match the port |
| Mail on phone but not laptop | One device is on POP3 and removing mail from the server — switch both to IMAP |
| Sent mail missing on other devices | The app is saving to a local Sent folder instead of the server’s |
| Nothing arrives at all | Wrong incoming server, or a firewall blocking the port |
