Yes, you can migrate IMAP emails to Office 365 while keeping the original folder structure. I had to move an old IMAP mailbox to Microsoft 365, and the manual options seemed fine for a small mailbox, but they became difficult to manage once multiple folders and years of emails were involved.

After comparing a few approaches, I used the Softaken IMAP to Office 365 Migration Tool for the migration. Once the transfer was complete, I checked several folders to make sure the emails, attachments, and folder hierarchy matched the source mailbox. Everything appeared in the correct folders in Office 365, so there was very little cleanup required after the migration. This approach worked well for preserving mailbox organization during the move.
