I am trying to use Thunderbird to transfer my emails from my Microsoft 365 (formerly Office 365) account to a new email provider. The problem I am running into is that my folders don't appear under my Inbox for my Microsoft 365 account. I have tried adding the account then restarting Thunderbird as well as removing then re-adding the account. I have also tried just walking away in case it was just a matter of slow loading. What can I do to fix this?
