I am attempting to run this command:
Get-Mailbox | Search-Mailbox -SearchQuery '(Received:01/01/2010..31/12/2013)' -DeleteContent
but I receive error message:
A parameter cannot be found that matches parameter name 'DeleteContent'.
I have searched this error message online and viewed other solutions like ensuring the account has Mailbox Import Export Role. I checked and this role is part of Organization Management, which Administrator is a member of.
