A T-Online address often outlasts several jobs, laptops and phones. The mailbox behind it ends up holding years of invoices, contracts, travel bookings and family photos. Then one day the storage warning appears, or your employer moves everyone to Microsoft 365, and you have to decide what to do with all of it.<\/p>\n

This guide shows you how to migrate T-Online emails to Office 365 in three ways: through Outlook, through the Exchange admin center, and with a Cigati IMAP Backup Tool<\/strong><\/a>. It also covers the preparation that prevents most failed migrations.<\/p>\n
