We made a change to the OneNote API to set a page limit at the section level. This affects the Create page scenario.

When this limit is reached for a section and an attempt is made to create a new page in that section, you will see a response with HTTP status code 507 and message “Exceeded the maximum number of pages allowed per section”. For more information on this error code, see OneNote Error Codes.

This change addresses issues we have uncovered on our end with sections with too many pages, which impacts our ability to provide the best possible experience to all of our customers.

You can use one of the following workarounds:

• Create a new section and add new pages there.
• Delete unused pages of an existing section that has reached the page limit.

We understand this change may cause some inconvenience, but we are confident that it will ensure a more reliable and performant experience overall!
