Step 1: Connect Both Email Accounts

Open your preferred desktop email client and add both the old and new email accounts.

• In Outlook, go to File then Add Account

• In Thunderbird, go to Settings then Add Account

• In Evolution, go to Preferences then Mail Accounts then Add

• In Apple Mail, go to Mail then Add Account

Make sure you use IMAP for both accounts so your folders and messages stay synced properly.

Step 2: Copy or Move Your Email

Once both accounts appear in your client, you can simply move your messages.

1. Expand both account folders in the sidebar.

2. Select the folders or messages you want to keep.

3. Drag them from your old account into either

   • Local Folders (for a backup on your computer)

   • Your new account (to upload everything into the new service)

This process copies your messages from the old server to the new one. Larger accounts may take time to finish syncing, so let it complete before closing your email client.

Step 3: Verify and Clean Up

When syncing is complete, check your new account to make sure all folders and messages appear correctly.
If you backed up to local folders, you now have a safe offline copy of your entire mailbox.

You can now remove the old account if you wish or keep it as an archive.

Simple Tips

• Always use IMAP instead of POP for both accounts

• Let your client stay open until syncing is done

• Avoid moving too many large attachments at once

• Create a backup copy of your local folders if you plan to delete the old account

Final Thoughts

That is all it takes. Connect both accounts, move your folders, and your email is safely backed up or transferred to your new service. It works exactly the same way in Outlook, Thunderbird, Evolution, and Apple Mail.

With just a few clicks, your messages are secure, organized, and ready for use anywhere.
