Hi,
No, its most external appointments. For instance:
1) Somebody sends me an invite to a meeting from the states, I accept in outlook - appears in outlook diary, not on Android devices
2) I get an appointment on my works email, I forward this onto my own email system, I accept there, it appears in outlook but not on my droids
3) I create an appointment on my outlook, that appears on my outlook and DOES go to my droids
Its only external appointments.
