The event are not correctly sync with Outlook #811

Hi,

I am using TbSync 5.3.5, and I am experiencing an issue with event synchronization. When I accept an event invitation, the event appears in Thunderbird. However, it never appears in my Outlook calendar.
If the event is created in Thunderbird, it is correctly synchronized and it appear in Outlook calendar.

Has anyone experienced this issue or knows how to resolve it?

Thank you.
