I recently went from 365 home plan to 365 small business plan. The support team helped me with a migration but unfortunately all my ToDo tasks didn't migrate :(
I found this official article: https://support.microsoft.com/en-us/office/exporting-your-microsoft-to-do-account-d286b243-affb-4db4... explaining how to export my mailbox including todo tasks from outlook.com.
I started the export more than a week ago and it haven't finished yet so I need help to either moving todo tasks from my home plan to my business plan or help to stop the hanging export process in order to restart it.
I currently using outlook.com from a mac and have tried in different browsers (firefox and chrome) with no success.
