I am writing this information for those education institutions and their IT administrators who wants to integrate Office 365 Education subscription with their existing Moodle LMS system.
Microsoft and Remote-Learner have just released the first versions of a series of plug-ins that makeOneNote and Office365 for Business integration with Moodle available. We have also updated the Oembed filter to provide pluggabiluty for Microsoft Mix applets.
You can get the OneNote set of plugins here: https://moodle.org/plugins/browse.php?list=set&id=71
You can get the Office365 for Business set of plugins here: https://moodle.org/plugins/browse.php?list=set&id=72
The Oembed filter is available here: https://moodle.org/plugins/view/filter_oembed. It may still be out of date, but will be updated shortly.
There is information in each plug-in set on how to install and use it, and there is further documentation available as well. I also discussed the development in several posts on my blog, starting with this post. Each subsequent posts expands a bit more on the functionality.
