Comcast to Yahoo Email Migration FAQ

What is the Comcast to Yahoo email migration?
Comcast (Xfinity) is transitioning all active @comcast.net email accounts to Yahoo Mail as the hosting provider, starting in June 2025. Your email address (@comcast.net) will remain the same, but you’ll access it through Yahoo Mail’s platform, which offers updated features. This change does not affect other Xfinity services like internet or TV.

When will my email account be migrated?
The migration is happening in phases, starting June 2025. You’ll receive an email from Comcast about 30 days before your specific migration date, followed by a second email closer to the date with a link to complete the transfer. Check your inbox or spam folder for these notifications.

What do I need to do to complete the migration?

• Sign in at login.yahoo.com using your full @comcast.net email address and Comcast password.
• Accept Yahoo’s Terms of Service and Privacy Policy.
• Repeat for each @comcast.net account you have.

What happens to my emails, contacts, and folders?

• Migrated: All emails, contacts (up to 10,000), and folders (up to 4,100) will transfer automatically.
• Exceptions: Folder names over 240 characters will be shortened. Folders matching Yahoo’s default names (e.g., “Sent”) will be renamed. Excess folders may be consolidated.
• Large Emails: Emails over 25MB won’t migrate automatically. You must download and delete them before migration, or they’ll be placed in a special folder post-migration, where you have 30 days to download/delete them before permanent deletion.

How long do I have before my email data is deleted?

• 30 Days: After your migration starts, you have 30 days to accept Yahoo’s terms. If you don’t, you’ll lose access to your email (can’t read, send, or receive) until you complete the process.
• 120 Days: You have up to 120 days from the migration start date to fully accept the terms. If you don’t, your @comcast.net account will be closed, the email address will be lost, and all data (emails, contacts, folders) will be permanently deleted.

What happens if I miss the 30-day window but am within 120 days?
If you’re past the 30-day window but within 120 days, you can still log in at login.yahoo.com, accept the terms, and regain access without data loss. Contact Xfinity support (1-800-XFINITY) if you need help.

Can I opt out of the migration?
Yes, but opting out means closing your @comcast.net account. You’ll need to download your data (emails and contacts) beforehand, as the email address and all data will be permanently deleted.

How can I back up my email data before migration?

• Emails: Export using an email client like Outlook (IMAP: imap.comcast.net, port 993, SSL/TLS) or download from the Xfinity web interface.
• Contacts: Save as a CSV file from the Xfinity email interface.
• Large Files: Search for emails over 25MB and download/delete them to avoid migration issues.

Will I need to update my email settings on devices or apps?
Yes, after migration, reconfigure third-party email apps (e.g., Outlook, Apple Mail) with Yahoo’s settings:

• IMAP Server: imap.mail.yahoo.com, port 993, SSL/TLS.
• Enable “Allow apps that use less secure sign-in” or generate an app-specific password in Yahoo’s account settings.

Where can I get more information or help?
