Event modification problem

I made a backup from users, and changed the domain of host, calendar etc. Now users can't modify events even if they are owners of the calendar. the window shows a summary tab and reminders tab only. The old user (meaning with old domain, because user name is the same) is shown as organizer and in attendees. Is it possible to modify events, even if I had to do this with another user ?

Thank you
