Recurring meeting vanished from Organizer Calendar - Outlook 2010

Hi Experts,

I have a personal assistant complaning her recurring meeting vanished from her Calendar(blue on the screenshot). It was a recurring meeting.
I could confirm the recurring meeting it was being showed on someone's else calendar(green on the screenshot) and even in the meeting room(pink on the screenshot).
I cannot find the recurring meeting in the personal assistant mailbox. Not even in the Deleted items. Now she cannot make changes on the meeting even she is the organizer.
How cannot copy this recurring meeting back to her calendar?
I tried to keep the Ctrl pressed while draging to her calendar, but just one was copied. I would need to copy the whole recurring meeting and give her the hability to keep making changes?

Is this possible?

Best Regards

What version of Exchange are you using? If the item is no longer on the organizer's calendar, the organizer will have to create a new meeting. Before you do that, you can enable the Calendar Repair Assistant, which will remove the orphaned meeting all other calendars. Here is information on the CRA -
