Quick answer
- One folder: add Yahoo to classic Outlook over IMAP, then run Import/Export and choose Comma Separated Values.
- No Outlook: use Thunderbird with free ImportExportTools NG add-on, which lists CSV for message exports.
- Many folders or accounts: Corbett Yahoo Backup Tool saves Yahoo Mail as CSV with filters.
You want to export Yahoo emails to CSV so you can sort, search and count your mail in Excel or Google Sheets. Yahoo Mail has no button for that. You get there through a mail program that connects over IMAP, or with software. Below are three ways to export Yahoo emails to CSV, what a CSV file keeps and fixes for sign in errors.
What does a CSV hold when you export Yahoo emails to CSV?
A CSV file is plain text with one row per message. When you export Yahoo emails to CSV you get readable fields such as subject, sender, recipients, date and body text, ready for a spreadsheet. A row cannot hold an attachment file, a folder tree or a mail layout. Exact columns depend on your program, so open one file before you rely on it.
That makes CSV right for reports, audits and lists. It is a wrong choice for backups. For a full copy that keeps attachments, save PST, MBOX or EML as well. Our guide to save Yahoo emails to computer covers those formats.
How to export Yahoo emails to CSV with Outlook?
To export Yahoo emails to CSV with Outlook, connect your Yahoo account over IMAP, let it sync, then run Outlook's export wizard. That wizard exists in classic Outlook only. If your File menu has no Open & Export, you are in new Outlook and need to switch to classic first.
- Sign in to Yahoo Account Security and create an app password under External connections. Copy that code.
- In classic Outlook, select File, then Add Account and enter your Yahoo address.
- When Outlook asks for a password, paste your app password instead of your usual one.
- Wait for your Yahoo folders to finish syncing, so your export Yahoo emails to CSV run sees every message.
- Select File, Open & Export, then Import/Export.
- Choose Export to a file, then Comma Separated Values.
- Select one Yahoo folder you want, choose where to save and select Finish.
Limits: Outlook exports one folder per run. A Slipstick poster asked how to run that wizard on all folders, said it is limited to one folder and did not think it includes subfolders. That thread shows no reply or fix. Repeat for every folder, or use software. Add Account and Import/Export menu names are general Outlook behavior, so check them in your version.
How to export Yahoo emails to CSV with Thunderbird?
To export Yahoo emails to CSV without Outlook, use Thunderbird with free ImportExportTools NG add-on. Its listing says it exports all messages in a folder as EML, HTML, PDF, CSV or plain text, and exports an index of a folder as plain text or CSV.
- To export Yahoo emails to CSV here, add your Yahoo account to Thunderbird over IMAP and sign in with Yahoo's sign in window or an app password.
- Let your folders sync, then install ImportExportTools NG from Thunderbird's add-ons page.
- Right click a Yahoo folder you want and open add-on export options.
- Choose CSV option for messages or for folder index, then select a destination folder.

How to export Yahoo emails to CSV with software?

What Yahoo settings do you need?
To export Yahoo emails to CSV from any mail program, you need these values. Yahoo's help page lists them for IMAP.
- Incoming IMAP server:
export.imap.mail.yahoo.com, port 993, SSL required. - Outgoing server:
smtp.mail.yahoo.com, port 465 or 587, SSL and sign in required. - Username: your full Yahoo address.
- Password: your account password, or an app password if Yahoo rejects it.
Yahoo's page says an app password is needed for Yahoo Account Key or some older apps. Corbett's Yahoo page says that with two step verification on, a normal Yahoo password is rejected by every mail client. It also says Yahoo still keeps an IMAP switch under Settings, More Settings, then Mailboxes, so confirm IMAP access is on. Delete your app password when you finish, since changing your Yahoo password does not cancel it.

Why does export Yahoo emails to CSV fail?
Yahoo rejects your password in Outlook or Thunderbird
A Mozilla Support user in February 2026 got "Authentication error, LOG IN invalid credentials" while adding Yahoo to Thunderbird for Android, and changing that Yahoo password did not help. A reply said Yahoo no longer supports basic sign in and suggested OAuth 2.0 or a 16 character app password, and it was marked as AI generated. That thread shows no confirmed fix. Create an app password as shown above.
Import/Export is missing in Outlook

That covers one CSV export run. Repeat it for every folder, or use Corbett Yahoo Backup Tool to tick all folders and subfolders.

CSV file is missing attachments
A CSV row holds message text, so attachment files are not inside it. Export PST or EML too, or pull files with a separate run.
What to do after you export Yahoo emails to CSV?
After you export Yahoo emails to CSV, open your file in Excel or Google Sheets and check dates, senders and body text on a few rows. Keep your Yahoo mailbox until you confirm counts. Yahoo empties a mailbox left unused for 12 months, according to Corbett's page, so keep a second copy of your file.
Our view
Outlook exports one folder per run, so large Yahoo accounts take many passes. Use software for all folders at once, and open one test file before trusting columns.
