Are you planning to migrate emails from Roundcube webmail to Outlook.com but don’t know the right way to do it? You’re not alone. Many users and businesses want to leave Roundcube due to its limited features and switch to Outlook.com for better security, accessibility, and email management.

However, migrating emails from Roundcube to Outlook.com is not as simple as clicking a button. IMAP configuration, large mailbox size, and folder structure issues can confuse non-technical users.

That’s why this guide explains two reliable ways to migrate emails from Roundcube to Outlook.com:

  • One manual (free) method
  • One professional (automatic) method

You can choose the approach that best fits your needs.

Let’s begin.

Why Migrate Emails from Roundcube to Outlook.com?

Many users decide to switch from Roundcube to Outlook.com because:

  • Outlook.com offers a cleaner and modern interface
  • Better spam and security features
  • Easy access on mobile, desktop, and web
  • Smart email rules and focused inbox
  • Integration with Microsoft apps like OneDrive and Calendar

How to Import Roundcube Emails into Outlook.com Manually?

Step 1. Log in to your Outlook.com account. If you don’t have one, create it first.

Step 2. Click on the Settings or gear icon in the top-right corner.

Step 3. Go to Mail >> Sync email.

Step 4. Under Connected accounts, choose Other email accounts.

Step 5. Enter your Roundcube email address and password.

Step 6. Provide IMAP details, such as required.

Step 7. Click OK to start syncing.

Outlook.com will now begin importing emails from your Roundcube mailbox.
