Problem with exchange calendar access


I have a calendar shared from exchange with [email protected] and when i want to add an event on the calendar with my adress ([email protected]) i have this issus on the event log:

MailClient.Storage.Application.OperationException: The request is invalid., Your request can’t be completed. You can’t change a Private calendar event on a calendar that’s been shared with you.

It look like access permission but i dont have the problem when i am using exchange or iOS or OSx. When i create a new event from EmClient with [email protected] the event appears on my calendar but is set “private meeting”.

I am set as Editor in the Exchange config and that should work but no, can someone help plz ?

Best regards.
