I've used MM for years with previous Office and few issues
- MindManager has never been integrated with Office 365 applications
- MindManager won't integrate with Office 2016 at the earliest with the new release in Oct 2015 (There is a hint about the new release but not Office 2016 in Mindjet's online shop).
"MindManager 2016 is fully compatible with Office 2016. This was confirmed by our solution team last week. Release date is early October."
I think the office 365 aps are standard desktop office 2016 aps so all should be good. I'll post the outcome - so long as i remember!
