Migrate T-Online to Gmail: Secure & Local Transfer
Moving away from T-Online (Telekom) to Gmail? Online import tools often fail due to Telekom's strict external password policies. With the Mailriva desktop app, you handle this securely. Copy your entire T-Online mailbox directly to Gmail via IMAP.
Why moving from T-Online to Gmail is not straightforward
T-Online to Gmail is one of the most requested migration paths, but migrating away from Telekom can be surprisingly tricky. There is no built-in export function, and Telekom has changed its authentication requirements over the years. If you have an older @t-online.de address, you may need a separate app password. Mailriva guides you through this process.
Direct Server-to-Server
Mailriva connects T-Online and Gmail locally on your computer via IMAP and copies all folders, emails, and attachments.
Folder Structure Preserved
Inbox, Sent, subfolders — everything is recreated 1:1 in your new Gmail account.
T-Online Stays Untouched
Your T-Online mailbox remains completely unchanged after the migration.
Works with All Telekom Addresses
Supports older @t-online.de and newer @magenta.de addresses equally.
