How to Migrate from Shared Mailbox to Microsoft 365?

To migrate from a shared mailbox to Microsoft 365, you need a method that preserves folder hierarchy, handles large mailboxes, and transfers everything smoothly to the new account. Manual methods often require multiple steps and may not support shared mailboxes directly. The SysInfo Office 365 Backup Tool simplifies the job by allowing admin login through Modern Authentication, showing a detailed preview of the shared mailbox, and letting you migrate all items—emails, contacts, calendars, tasks—directly into the selected Microsoft 365 mailbox. It also offers useful features like skipping previously migrated data, removing duplicates, applying filters, and backing up shared or public folders as needed.
