Comcast Backup Tool for Xfinity Mail

A Comcast address belongs to the internet plan. Move house, switch provider or close the account and the mailbox can go with it. Webmail also offers no export button. Comcast Backup Tool saves Xfinity folders to a local drive before that day arrives.

Comcast Mail Stops When Service Does

Many people sign up for Comcast mail through their cable or internet plan. When that plan ends, the address and its old messages may disappear too. A full local copy keeps bank letters, receipts and family photos readable.

Core features

Back Up Comcast Email in Four Moves

Open the wizard, add the Xfinity login, preview the folders and set the output.

Add the Xfinity Mail Address

Enter the Comcast address and password, then press Find. The tool looks up the IMAP server and port without help. Xfinity may ask for a separate security code for outside mail programs.

Find button detects server and port
Comcast.net and Xfinity.com addresses
Many logins in one session
A lost connection resumes where it stopped

Folder selection

Select Comcast Folders for the Backup

Every folder and subfolder loads with a message count. Mark the ones worth keeping and clear Spam and Trash to save space.

Any folder or subfolder can be ticked or cleared
Message counts shown at a glance
Parent and child layout preserved
Spam and Trash left out in one click

Message preview

Preview Comcast Emails Before Saving

Open any message and inspect it in four views before a single file is written. A wrong folder or an empty thread shows up early.

Content shows body text, sender, recipients and subject
Message header records the route the email travelled
Properties holds size, flags and attachment names
Hex and raw views present the stored message code

Selective backup

Search and Filter Comcast Mail

A quick search finds mail by name, subject, From, To, CC or date. Save one sender, one year or one thread and leave the rest in the Comcast mailbox.

Date filter for any period
Name, subject, From, To and CC search
Messages with attachments only
Contacts and email addresses saved alone
Large mail sets processed in one go
Output saved to an internal or external drive

Output options

Xfinity Mail Output: Drives or New Accounts

Files can go to a hard drive or flash drive, or the mail can load into a new account. Those leaving Comcast often keep an archive file and open a Gmail or Outlook mailbox for daily use.

PST, MBOX and EML for Outlook and Thunderbird
HTML, CSV, TEXT and vCard for documents and contacts
A direct move to Gmail, Yahoo or Microsoft 365 also works through the IMAP Migration Tool

Before connecting

Comcast Sign-In Checks

Three details keep the first login from failing.

Must do

Allow outside mail programs

Comcast can block mail apps by default. Open the Xfinity account settings and look for the third party access option or a security code, then use that code in the tool.

Common snag

Use the full address as username

Logins are normally the entire address ending in comcast.net or xfinity.com. Dropping the domain part often triggers a password error.

Server details

IMAP on port 993 with SSL

Comcast mail normally uses an IMAP server with SSL on port 993. If Find returns nothing, enter the server by hand in advanced settings.

Other mail hosts that end with service plans are covered in Configure Comcast emails in Thunderbird and Backup Verizon emails.

Before purchase

Webmail Printing vs Comcast Backup Tool

Xfinity webmail can print or forward one message at a time. That suits a few letters. Years of mail call for batch tools, and the table shows the gap.

Task	Webmail by hand	Comcast Backup Tool
Cost	Free	$99 one time
Keep a single email	Print to PDF	Works too, with extra options
Save thousands of emails	Many hours of clicking	One batch run
Find mail by date or sender	Manual scrolling	Name, subject, From, To, CC and date search
Save contacts and calendars	Not offered	Exported to standard formats
Format choice	Print or forward only	Email client and document formats
Folder layout	Lost in a flat pile	Hierarchy rebuilt in the output
Size limits	Set by the browser session	No cap on file size

Green rows show where webmail is sufficient.

A handful of messages can leave Xfinity by printing at no cost. Moving a complete Comcast mailbox to Gmail is laid out in Transfer Comcast emails to Gmail .

Common questions

Comcast Backup Tool FAQs

Logins, search, formats and the demo limit.

How do I save Comcast emails to my computer?

Install the tool, add your Comcast address and password and press Find. Select folders, preview a few messages, choose a format and start the backup.

Are attachments saved too?

Yes. Every attachment stays with its message and no content is lost. A separate folder can hold the files.

Can I back up many emails at once?

Yes. The tool handles large sets in a single run and loads the mailbox quickly.

Can I limit the backup to a date range?

Yes. The advanced search bar has a date filter, so mail from one range can go to any internal or external drive.

Can I save mail from one sender only?

Yes. Apply the email filter, select the address and run the export.

Does it save Comcast contacts and calendars?

Yes. Contacts, calendars, tasks and journals can be saved in standard formats next to mail.

Which formats does it offer?

PST, MBOX and EML open in mail clients. HTML, CSV, TEXT, vCard and PDF serve documents and contacts.

What if Find cannot locate the server?

Open advanced settings and fill in the server address and port manually. Port 993 with SSL is typical for Comcast accounts.

Why does Comcast reject my login?

Outside mail programs may need a third party security code from your Xfinity account. Enter that code instead of the usual password.

Do file sizes matter?

No. The tool puts no restriction on file size. Big mailboxes only take more time.

Does Corbett receive my messages?

No. The PC connects to Comcast directly and Corbett never sees the mail.

Is Comcast Backup Tool available for Mac?

No. Windows 7 to 11 and Windows Server 2008 to 2016 are supported.

What does Comcast Backup Tool cost?

The $99 price buys a lifetime licence with a refund period of 30 days.

What does the demo do?

The demo has all features on and saves ten emails from every folder.

Can I use it after cancelling Comcast?

Not for mail on the server. Once Comcast closes the account the mailbox is gone, so run the backup before cancelling.

Manual methods fell short

This is a very useful tool. I wanted to backup all of my Comcast emails. I tried many manual methods but it didn’t help. Then, I came across this tool. It not only helped to export but also ensured complete data integrity.

Myra Jones

Task finished without interruption

I wanted to keep a backup of my entire Comcast emails in local hard drive. Then, I downloaded the ‘Comcast Email Download Software’ which completed the task without any interruption. I really appreciate the performance of the tool.
