Here is the scenario: We had a user that created a calendar event that was sent out to others in his dept. The user has since left the company and his user was deleted. I have a request to remove the calendar event he created. I do not know who or how many others were sent this calendar event.
I tried this powershell string but it did not work:
Get-Mailbox | Export-Mailbox -SenderKeywords "Username" -SubjectKeywords "enter keywords here" -IncludeFolders "\Calendar" -DeleteContent
We are running Exchange 2007.
