Migrate GMX to Outlook: Fast & Secure Local Transfer
Moving your GMX.com mailbox to Microsoft Outlook? Since Microsoft removed the ability to connect external IMAP accounts in the Outlook web interface, migrating directly in the browser is no longer possible. With the local Mailriva desktop app, you bypass this restriction: Transfer your entire GMX mailbox directly into your new Outlook account via a secure IMAP connection.
Why the official way is often not enough
Microsoft has removed direct support for connecting new third-party accounts in Outlook.com. This means there is no longer a built-in migration assistant for old personal accounts. Mailriva fills exactly this gap — locally, controlled, and without entering your passwords in a browser.
Direct Server-to-Server
Mailriva transfers GMX to Outlook via IMAP and copies all folders, emails, and attachments.
Folder Structure Preserved
Inbox, Sent, custom folders — everything is recreated 1:1 in your new Outlook account.
GMX Stays Untouched
We strictly copy your data. Nothing is deleted, moved, or marked as read in GMX.
Purely Local, No Web Tool
The app runs on your computer. Your credentials are never uploaded to any server.
