Credicorp email troubleshooting

Common problems with Credicorp email and how to fix them — can’t connect, can’t send, mail not syncing, certificate warnings and wrong-username errors.

Most email problems come down to one of a handful of settings being slightly wrong. Almost everything on this page is fixed by checking your settings against the values below and re-typing your username and password carefully.

Can’t connect at all

If your app can’t reach the mailbox — you see “cannot connect to server”, a timeout, or the account never finishes setting up — the incoming server, port or security type is the place to look.

1. Server name: set the incoming server to mail.credicorp.co.uk. Don’t use webmail.credicorp.co.uk, an old provider’s host, or just credicorp.co.uk.
2. Port and security: incoming is port 993 with SSL/TLS. If your app is set to port 143 or to “no encryption”, change it.
3. Use IMAP, not POP. Credicorp is IMAP only. If your account was added as POP, remove it and add it again as IMAP.
4. Check the network. Some public Wi-Fi, captive portals, corporate firewalls and VPNs block mail ports. Try a different network (for example your phone’s mobile data) to rule this out.

Can receive but can’t send

If mail arrives but your messages sit in the outbox or fail to send, the problem is in the outgoing (SMTP) settings — not your incoming mail.

1. Server name: outgoing server is mail.credicorp.co.uk (the same as incoming).
2. Port and security: outgoing is port 587 with STARTTLS.
3. Turn outgoing authentication on. SMTP requires authentication. Set it to use the same full email address and password as your incoming server. The single most common cause of “receive works, send fails” is authentication being switched off for outgoing mail.
4. Avoid port 25. Many networks block port 25 for sending. Use port 587 with STARTTLS as above.

Mail not syncing

Credicorp email uses IMAP, so your mail lives on the server and stays in sync across every device. If new mail isn’t appearing, or folders look out of date:

1. Confirm it’s set up as IMAP on port 993 with SSL/TLS. A POP account downloads and removes mail and won’t stay in sync — remove it and re-add as IMAP.
2. Check the mail actually arrived. Sign in at webmail.credicorp.co.uk. If the message is there but not in your app, the problem is local to the app, not the mailbox.
3. Refresh or restart. Pull to refresh, or close and reopen the app. On a phone, check that background refresh / sync is allowed for your mail app.
4. Re-check the saved password. An out-of-date password can leave an account “connected” but silently failing to update. Update it for both incoming and outgoing.

Certificate or security warnings

The mail server presents a TLS certificate issued for mail.credicorp.co.uk. A warning almost always means the server name you typed doesn’t match the certificate.

• Use mail.credicorp.co.uk exactly for both incoming and outgoing. If you entered webmail.credicorp.co.uk, an old hostname, or a provider’s server, the name won’t match and you’ll be warned.
• Don’t accept untrusted or self-signed certificates. A legitimate Credicorp connection never asks you to trust an exception. If you’re prompted to, stop — double-check the server name first.
• Never turn off TLS or SSL to silence a warning. Keep SSL/TLS for incoming and STARTTLS for outgoing.
• If the name is correct and the warning persists, note the exact wording and contact support@credicorp.co.uk rather than bypassing it.

Username or password rejected

If you’re sure the password is right but sign-in keeps failing, the username is the usual culprit.

1. Use your full email address as the username — for example name@credicorp.co.uk, not just name. This applies to both incoming (IMAP) and outgoing (SMTP).
2. Re-type the password carefully. Check Caps Lock is off and there’s no stray space at the start or end.
3. Update a changed password everywhere. If you recently changed it, your app may still be sending the old one. Update the saved password on every device, for both incoming and outgoing.
4. Pause if it keeps failing. Repeated failed attempts can temporarily lock the mailbox. Stop, fix the settings everywhere, then sign in once.
5. Test in webmail. If webmail.credicorp.co.uk also rejects the password, you need a reset — see Passwords & signing in.

Still stuck?

If you’ve checked your settings against the table above and you still can’t connect, send or sign in, email support@credicorp.co.uk from an account we can reply to. Tell us the mailbox address, the device and app you’re using, and the exact error message you see.
