Learn About Opera Mail

Opera Mail is a component of the Opera Internet Suite. One such application, which has incorporated an email and news program, has been popular among its users for quite some time. Though previously built into Opera Browser, it has a separate entity following Opera version 15. As a single application, News Feed lists a user with many impressive features, including POP3 and IMAP account management, a contact manager, spam filtering, Atom, and RSS feeds, etc.

Where are Opera Mail emails stored?

The exact location of the Opera Mail varies depending on the operating system:

  • Windows: C:\Users\[YourUsername]\AppData\Local\Opera Software\Opera Mail or C:\Users\[YourUsername]\AppData\Roaming\Opera Software\Opera Mail.
  • macOS: /Users/[YourUsername]/Library/Application Support/Opera Mail
  • Linux: ~/.opera/mail

Manually Import Opera Mail to Outlook Account

We can export the emails from Opera Mail in MBOX format, but this can’t be opened directly in Outlook. Therefore, we need a bridge between these two email clients to make the migration smooth. 

Method 1: Use Thunderbird as the Intermediate Client

In this method, we are using Thunderbird to convert the MBOX files before importing them into Outlook.

Step 1: Export MBOX File from Opera Mail

  1. Open Opera Mail 
  2. Locate the mail storage location.
  3. Copy the required MBOX files to the system

Step 2: Import the File into Thunderbird 

  1. Install Mozilla Thunderbird. 
  2. Install the ImportExportTools NG add-on. 
  3. Right-click the local folder.
  4. Select ImportExportTools NG > Import MBOX File.

Now, you have the Opera Mail MBOX in Thunderbird.

Step 3: Add Account to Outlook and Complete the Import process

Now, we need to configure the same Thunderbird and Outlook using IMAP.

  1. Add any email account in Thunderbird using IMAP.
  2. Add the same account to Outlook using IMAP.
  3. Now, drag and drop the emails from the Thunderbird local folder to the IMAP folder.
  4. Open Outlook and sync the emails.

Limitation: The method requires technical knowledge to complete the procedure, such as configuring an email account using IMAP settings. Additionally, the entire process is time-consuming.
