After migrating our exchange environment to Office 365, some users who are on iOS9 are sending out calendar acceptances for re-occurring scheduled meetings.
I am re-opening cases with both MS and Apple, but we have followed the advise of them by scrapping all ActiveSync associations of the user(s) in question on office 365. Disabled and re-enabled ActiveSync and setup from scratch with their E-Mail but the same issue occurs.
Around 15mins before the meeting is scheduled it will send out a acceptance to either a internal or external recipient that is a critical issue for us at the moment.
We also use MDM for our corporate iPhones, but our devices go directly to office 365 and MDM just feeds information back to ensure the devices is in compliance.
Has anyone any further troubleshooting steps for this case
