Legacy email software
Outlook Express is obsolete and should not be used for a live business mailbox
This page remains for customers recovering an old computer or identifying historic settings. Outlook Express belongs to unsupported versions of Windows and cannot be relied upon for current security and TLS standards. Move the mailbox to a supported version of Outlook, Apple Mail, Thunderbird or another maintained app.
Why is the old video no longer the right setup method?
Old encryption support
Historic clients and operating systems may not support the TLS versions and certificate checks expected by current mail servers.
No security maintenance
Outlook Express is not receiving fixes for newly discovered vulnerabilities or modern authentication behaviour.
Different menu paths
Current Outlook is a different product. Instructions for Tools, Accounts and old identity files do not match it.
Local-only messages
POP configurations may have removed mail from the server, leaving the only copy inside the old computer profile.
What should I do with an old Outlook Express installation?
- 1Do not delete the profile
Keep the old computer and its user files intact until important mail and contacts have been exported and checked.
- 2Identify local mail
Compare the folders with webmail. Messages missing from webmail may exist only in the Outlook Express data files.
- 3Export or migrate
Use a trusted migration process suitable for the old Windows version, ideally while the computer remains offline.
- 4Configure a maintained app
Add the mailbox to a current device using the full email address, mailbox password and secure server settings.
What are the current UKC mailbox settings?
| Service | Server | Port and security |
|---|---|---|
| Custom Domain Email | webmail.ukc.uk | IMAP 993 SSL/TLS, SMTP 587 STARTTLS |
| Shared hosting mailbox | Your assigned server, such as ukc10.uk through ukc13.uk | IMAP 993 SSL/TLS, SMTP 587 STARTTLS |
| Username | The complete email address, with SMTP authentication enabled | |
SMTP port 465 with implicit SSL/TLS is an alternative when an application supports it. POP 995 is available but IMAP is usually the better choice across several devices.
Legacy email questions
Can UKC make Outlook Express secure again?
No. The problem is the obsolete client and operating system, not a mailbox control that UKC can enable.
Will changing app delete my messages?
Adding the mailbox to a new app does not normally delete server mail. Old POP messages may be local only, so export and verify them first.
Where can I read current Outlook instructions?
Use the linked UKC Outlook guide. Current Outlook screens and capabilities differ substantially from Outlook Express.
Move to supported email
Recover any local mail, then configure a maintained application
Use the current guide and the certificate-safe server assigned to your mailbox.
