Thanks for reaching out!
To open your OneDrive notebook, please click on "+" icon at the top of notebooks pane > Open from OneDrive > log in > select the notebook. After it's fully downloaded you can change the format of your notebook: when changing the format, Outline creates the local copy of OneDrive notebook. You'll be able to close the initial OneDrive copy and continue working with this local copy.
Here is an article on how to change the format of notebook in Outline: http://help.outline.ws/customer/en/portal/articles/2744997-convert-notebook-to-onenote-format-and-vice-versa-on-mac
Please write to me if there are any difficulties. I will help!
