If I create an appointment on my Windows phone it appears in the PC Windows calendar app and on Outlook.com.
If I create an appointment on Outlook.com it appears in the PC Windows calendar app and on my phone.
If I amend an appointment in the PC Windows calendar app that was created on Outlook.com or on my phone it updates Outlook.com and my phone.
The problem is that if I create an appointment in the PC Windows calendar app it does not appear on Outlook.com or on my phone.
This used to work OK, I think that it may have stopped working with a recent update that introduced Family calendar.
I have tried all of the published methods for resolving calendar sync issues and none of them work.
The Windows calendar app shows 3 sections:
Cortana - Reminders
Microsoft account - Calendar <-- this is the one that doesn't sync
Outlook account name - Calendar <--- this one syncs
Can the Microsoft account calendar either sync or be removed?
A calendar that does not sync is of no use.
Can appointments in this calendar be moved or copied to a different calendar?
