Yes indeed. I did the updates and the plugin is working again for me as well.
Though there is still what I consider a bug--if you have not yet connected your Moodle account to Office365 and go to a OneNote assignment to attempt to submit something, the following error message appears:
"No OneNote API is available. If using the Office 365 plugin set, we were not able to contact OneNote. Otherwise, please install local_msaccount."
Only after separately connecting your Moodle account to Office365 via the Microsoft block does the assignment work.
Previously when I was testing this plugin, we were using local_msaccount for the non-office365 connection. When using local_msaccount there was a button on the OneNote assignment submission page that allowed you to connect your moodle account to o365. Can this be added back to the plugin? It was super helpful for users who had never used the Microsoft tools in Moodle to have the button there when they need it.
