Migrating Shared Mailbox to O365 Group?
That's a no on all questions. If you are used to the way you dealt with messages in the shared mailbox, stick with it. If you want to add some group-based functinality, such as Planner, you will have to adapt to the conversation based style groups use, and forget about (sub)folders, rules, categories, etc.
Office 365 Groups don’t function the same way as Shared Mailboxes, so what you’re seeing is expected. A Group mailbox is really just a single threaded inbox and doesn’t support creating custom folders like a shared mailbox does.
To your questions:
Do Groups have folders like a shared mailbox?
No—O365 Groups don’t allow folder creation. Everything goes into the main inbox.
Can you drag/drop old emails into a Group?
Yes, you can copy or move messages into the Group inbox through Outlook desktop, but since there are no subfolders, everything ends up in one place. The original threading won’t always be preserved.
Can you move Group conversations into your own mailbox?
You can copy individual messages, but once moved they behave like regular standalone emails.
When migrating a shared mailbox with a lot of content, doing it manually can be time-consuming. I used EdbMails Office 365 Migration to handle moving shared mailbox data into an O365 Group mailbox, and it worked fine for the bulk transfer—just note that the folder structure itself won’t carry over because Groups don’t support folders at all.
If your workflow relies heavily on folders or mailbox organization, sticking with a Shared Mailbox may still be the better fit.
