Outlook calendar integration not working for some users

[Rory_SSG]

I have recently activated calendar to status sync for specific users and have found that for the majority of users this works as expected.

However for myself the integration does not work, my status remains as available no matter what appointments I book in my outlook calendar.

The only thing that is different for me is i have system owner rights across all groups. Could this be a permissions issue? We are also using SSO and that works fine.

In addition to the SSO features working for the users that the calender sync does not, do these users not work with calendar sync-able sync sync sync their mailbox contacts to their 3cx personal phonebook?

Which 365 licenses are assigned to the affected users, please?
