Convert notebook to OneNote format and vice versa on iPhone

Last Updated: Feb 16, 2017 01:46AM PST

We keep supporting Microsoft OneNote notebooks in Outline and continue to improve display fidelity for those who need Microsoft OneNote.

In Outline we have two formats for notebooks to your choice: the native Outline format and OneNote format that allows you to work with OneNote and Outline at the same time.

The main difference between the formats is the way the attachments are stored:


       Outline File Format. Files have .outdoc and .outtoc extension.
      In Outline File Format attachments are held in separate folder (for example
      Having attachments arranged this way, Outline can download the notebooks faster: we open
      the text section files first.
      Attachments get downloaded later when you can already open the page and start typing.
      OneNote File Format. Files have .one and .onetoc2 extension. 
      In OneNote File Format attachments are encoded inside the general section files.
      It means you need to wait for all the attached files to finish downloading before the edits can
      be made.

When you create a new notebook in Outline, it is always created in Outline File Format.
