Backup Yahoo emails using Microsoft Outlook
Add Yahoo as an IMAP account in Microsoft Outlook
If you have Microsoft Outlook installed, you can add a new account for your Yahoo IMAP email account to have emails stored locally:
Open Outlook (2013, 2016 or later).
If it's the first time you're opening Outlook, a new window will ask you to enter your email address. After you add the email address, click on Connect.
If you already have other accounts defined, on the File tab, under Account Information, select Add Account. Select E-mail Account, and then enter your name and email address.
Enter the password for your email account. Click on Connect. Outlook will automatically configure the account by checking the connection, downloading the account settings and logging you in.
You'll see a Congratulations! message shown when everything is correctly configured. Select Finish, and then restart Outlook.
Access the newly created account in Microsoft Outlook and wait for the application to download your emails.
Configure Backup4all to back-up Microsoft Outlook automatically
Once you have your Yahoo emails on your local computer, you can configure Backup4all to automatically back them up:
Open Backup4all and select File -> New (Ctrl+N).
In the Where do you want to save the backup? section, select a backup destination.
On the What do you want to backup page, under "Applications" list, select Microsoft Outlook. This will automatically add all the necessary Microsoft Outlook files as a source for the backup.
On the Filter the backup sources page, you can set include/exclude filters for backup sources. Then press Next.
On the How do you want to backup page, you can choose the backup type and the encryption. It is recommended to leave Smart as the default backup type. Click Next.
On the When do you want to backup page, you can set the backup job to automatically run on the specified time and days. Press Next.
On the Personalize your backup job page, enter a name for the backup in the Backup name field.
Press Save and run to start backing up your Yahoo emails.
