  • Open the browser and log into Yahoo Mail on the web.
  • Right-click on the Profile icon (in the top right corner).
  • Select Account Info and go to the Account Security tab.
  • Scroll down and click Generate app password or Manage app passwords.

How to Backup Yahoo Email Folders? 5 Easy Methods

Here are the five easy & practical methods to back up Yahoo email folders conveniently:

Method #1: Use Desktop Email Client Via IMAP (Thunderbird, Outlook, Apple Mail)

Using desktop email clients that support IMAP is one of the most effective and reliable methods to back up Yahoo email folders on any desktop. Email clients like Thunderbird or Outlook use IMAP (Internet Message Access Protocol) to mirror your Yahoo mailbox on your computer. And once the mirror is configured, you can export Yahoo email folders to the hard drive.

The best part of using this Yahoo email folder backup method is that it maintains the exact folder structure and costs zero dollars! So, what are the best email clients for downloading Yahoo mail folders to the computer?

The gold standard email clients to “migrate Yahoo Mail folders to desktop” are as follows:

  • Mozilla Thunderbird (The First Choice)
  • Microsoft Outlook (Best for Office 365 Users)
  • Apple Mail (Best for Mac Users)

Let’s see how you can configure each email client to save Yahoo mailbox folders locally

Option #A: Mozilla Thunderbird

  • Open Thunderbird and go to File >> New >> Existing Mail Account.
  • Provide your name, Yahoo email address, and 16-digit App Password you have just generated. (Do not use the standard web password)
  • Click Done. Thunderbird will automatically detect and configure Yahoo’s IMAP settings.
  • Leave Thunderbird open for syncing. Depending on your mailbox size, it will take time.

Once Thunderbird fully syncs all the emails, apply the given steps:

  • In Thunderbird, go to the Add-ons and Themes menu.
  • Search for the ImportExportTools NG extension and install it.
  • Reboot Thunderbird.
  • In the left sidebar, select the Yahoo account folder.
  • Move the cursor over ImportExportTools NG and right-click Export all folders.
  • Finally, choose a destination on your hard drive.

Mozilla Thunderbird will save your email folders as MBOX files. It excels in preserving the original folder hierarchy and attachments. Amazingly, this file can be opened by almost any enterprise-grade, professional email client in the future.

Option #B: Microsoft Outlook

  • Open Microsoft Outlook and add the Yahoo account. To add your Yahoo account:
    • Go to File or View >> Add Account.
    • Enter your Yahoo account email address >> Advanced Options >> check the “Let me set up my account manually” box.
    • Choose IMAP and apply the following server details:

      Incoming Mail Server: imap.mail.yahoo.com
      Incoming Port: 993 (Encryption method: SSL)
      Outgoing Mail Server: smtp.mail.yahoo.com
      Outgoing Port: 465 or 587 (Encryption method: SSL or TLS)

    • Enter the Yahoo email address and the 16-digit App Password.
    • Hit Connect or Next to proceed for verification
    • Lastly, click Finish.
  • Once the IMAP sync is finished, go to File >> Open & Export >> Import/Export.
  • Click Export to a file >> Next.
  • Choose Outlook Data file (.pst) and select Yahoo Account.

It will save your Yahoo email folders as a .pst (Personal Storage Table) or .csv file. You can copy that file to a local drive, an external hard drive, or a USB flash drive. Also, you can re-import it for future Outlook 365 installations.

Option #C: Apple Mail (Built-in Mail App)

  • Open Apple Mail and add the Yahoo account to Apple Mail. To do so,
    • Go to System Settings >> Internet Accounts.
    • Click Add Account >> select Yahoo.
    • Sign in using the generated one-time App Password.
  • In the left sidebar, choose the specific email folders to export.
  • Go to the top menu bar, click Mailbox >> Export Mailbox.
  • Apple Mail will package the selected Yahoo email folders into an .mbox file.
  • To verify the content of the exported email folders instantly, right-click the .mbox file >> Open With >> Choose TextEdit, Sublime Text, or VS Code.

You can also use the same Apple Mail to open the .mbox file.

  • Simply go to File >> select Import Mailboxes
  • Click Files in mbox format >> select the File
  • The email folders will appear in the “Import” folder on the sidebar.

Method #2: Professional Third-Party Backup Software

When you have a massive mailbox, multiple Yahoo accounts, and need your emails saved in a specific document format (for legal or tax purposes), IT experts suggest automating the backup of Yahoo email folders. Probably one of the best methods for archiving Yahoo mail folders to a PC.

The reason is simple: Manual methods are indeed free, but they have serious limitations that can be intense and consuming. Such as;

  • The syncing process requires constant monitoring.
  • Fills up the local C: drive storage
  • Large mailboxes often time out

That’s why Industry Maestros advocates for professional backup software for easy and effective Yahoo email folder backup. And their most-preferred Yahoo backup tool is Systools Yahoo Backup Tool.

But why this? Because it can pull your mailbox data directly from Yahoo’s server to your hard drive. It means you don’t need any email client like Thunderbird to download Yahoo Mail folders to your computer

  • It guarantees the exact hierarchical email folder structure during the backup.
  • Its incredible data filtering feature enables selective backups of Yahoo email folders.
  • This enterprise-grade tool also provides support for multiple domain names, including Turbify Bizmail.
  • And, it is highly compatible with multiple Windows and Mac OS versions.

So, click the “Download” or “Purchase” button to use this advanced & automated method to export Yahoo email folders to a hard drive effectively!

Method #3: Cloud-to-Cloud Migration Services

Instead of looking for “how to download Yahoo Mail folder to computer”, you can also leverage Cloud-to-Cloud migration services to back up Yahoo email folders. Yes, with this advanced backup method, you can copy your entire Yahoo mailbox into another email provider like a Gmail or Outlook.com account.

In other words, you have to leave your computer running or monitor the sync. Simply start the Yahoo mailbox backup, turn off your computer, and receive an email when it’s finished.

  • To do so, you’re required to authenticate both your Yahoo account and the destination account on the cloud migration service’s website. Their server will secure the transfer in the background.
  • The only caveat is it’s a paid service, and some cloud migration services set limitations per folder. The prime example of it is VaultMe. It blocks copying to 10,000 emails per individual folder. Asks for splitting large folders manually before migrating.

Method #4: The “Print to PDF” Method (Best for Single Emails)

The “Print to PDF” or “Save as PDF” method is another way to back up a Yahoo email folder only if it contains a few critical emails. And you don’t mind the email folder structure! This super-effective method is ideal for securing singular emails with privileged information.

You can also save a Yahoo email as a Word document for effortless editing and sharing across professional settings. But if you’re planning to apply this method to a Yahoo email folder with 500+ emails + attachments, we advise you to use SysTool software! It will automate the complete process and save your precious time.

However, here are the simple steps:

  • Log in to Yahoo Mail on the web.
  • Open the target email >> select the More (three dots) menu.
  • Click Print >> Save as PDF.

Method #5: The POP3 Protocol

The POP3 Protocol is the legacy method used by IT professionals for years to export Yahoo email folders to a hard drive before IMAP took over. You can still use this method and set up an email client (Thunderbird or Outlook) via Yahoo’s POP3 server settings.

The email client redirects to Yahoo and exports the Yahoo email folder to the hard drive. And based on your settings, it often removes them from Yahoo’s server to save space.

But the reason why IMAP replaced it is that POP3 is completely ignorant of custom folders. It means if you have a structured folder on Yahoo, the POP3 protocol will download that specific Yahoo folder into a piled-up, unorganized “local” inbox.

Hence, consider this method to migrate Yahoo Mail folders to desktop only if you want a raw, unstructured data dump!
