We often encounter the problem on an ordinary morning: the browser displays an error instead of the inbox @numericable.fr, and nothing works anymore. The reflex to re-enter the password three times is not enough because Numericable’s webmail has changed its infrastructure since being acquired by SFR. Understanding what has changed on the server side and the retention periods allows for quick action before the account is permanently lost.
SFR Retention Periods: The Trap That Guides Forget
Before even touching the credentials, we check one point that conditions everything else: does the account still exist? The Postal and Electronic Communications Code (Article L44-1, law of December 17, 2009) requires SFR to maintain free access to emails received for 6 months after the internet contract is terminated.

The least known constraint concerns inactivity. After 6 months without any connection to the mailbox, SFR automatically blocks the receipt of new messages. One must then contact a representative to unblock access. After 12 months of inactivity, the account and all its data are permanently deleted.
If one has not checked their Numericable mailbox for over a year, the usual password recovery procedures will be useless. It’s better to call 1023 directly to check if the account is still active before wasting time on the reset form. To restore access to Numericable webmail under good conditions, this prior verification is the first concrete step.

Numericable Mail Servers: Updated Technical Settings
The old IMAP and SMTP settings for Numericable have been gradually migrated to the SFR infrastructure. If an email client (Outlook, Thunderbird, Mail app on an iPhone) displays connection errors, it is often because it is still pointing to outdated servers.
IMAP Settings for Receiving
- Incoming server: imap.sfr.fr, port 993, SSL/TLS encryption. The old server imap.numericable.fr normally redirects to this address, but some email clients do not follow the redirection.
- Username: the full address with the domain (@numericable.fr, @noos.fr, or @modulonet.fr depending on the case). Do not remove the part after the @.
- Password: that of the SFR Mail account, not the old Numericable password if it was changed during the migration.
SMTP Settings for Sending
- Outgoing server: smtp.sfr.fr, port 465, SSL/TLS encryption. Authentication is required with the same credentials as for IMAP.
- If port 465 is blocked (some corporate networks filter it), test port 587 with STARTTLS encryption.
- Feedback varies on this point: some users report that port 587 works better on mobile connections in 4G/5G.
A simple test to confirm that the settings work: send an email from the configured mailbox to another address (Gmail, Outlook.com), then reply from that external address. If both directions work, the configuration is correct.
Lost Password on an @numericable.fr Account: The Correct Procedure
The reset form can be found on the webmail.sfr.fr portal (no longer on the old webmail.numericable.fr, which now redirects). Click on “Forgot Password,” enter the full @numericable.fr address, and SFR will send a reset link to the registered backup address.
The common problem: the backup address was never provided, or it points to a mailbox that is no longer used. In this case, the only reliable option is through the SFR customer area. Log in to espace-client.sfr.fr with the landline or mobile number associated with the account, then go to the “My Account” section to change the email password directly.
If the SFR customer area refuses the login (credentials forgotten as well), the customer service at 1023 is still available. A representative can reset the password after verifying identity, but one will need to provide the contract number or the bank details associated with the direct debit.
Numericable Webmail Blocked by the Browser: Common Causes
When the username and password are correct but the page does not load, the problem rarely comes from SFR. Three situations frequently arise.
The browser cache retains an old version of the login page numericable.fr, which no longer exists. Clearing the cache and cookies for the domain numericable.fr and then sfr.fr resolves the issue in most cases. On Chrome: Settings, Privacy, Clear browsing data, check “Cookies” and “Cached images and files”.
A blocker or a security extension may interfere with the redirection process from numericable.fr to sfr.fr. Temporarily disabling extensions allows for verification. If the connection works without extensions, re-enable them one by one to identify the problematic one.
An outdated browser does not handle the SSL certificate for sfr.fr. On a Windows 7 computer with Internet Explorer 11, the connection to the webmail fails silently. Switching to Firefox or Chrome, even in portable version without installation, resolves the issue.
For inherited addresses (@noos.fr, @modulonet.fr), the procedure is the same. These historical domains are managed by the same SFR infrastructure and follow the same retention and reset rules as @numericable.fr addresses. The only difference: enter the full address with the correct domain, without replacing it with @sfr.fr.
One last point to keep in mind: the data of a Numericable account migrated to SFR is not saved elsewhere. No automatic copy is kept after deletion. If the account contains professional emails or archived documents, configuring an email client in IMAP and downloading messages locally is the best assurance against accidental loss.
