Yes it is a long time known that you have to put good passwords on managers mailbox or disable access to it through the pc tool
They also change the pass word to slow the changing back the fwd they set to prem numbers or the mailbox they set external delivery to prem lines
Lock down the vm ports to stop it making calls and block external fwd to extensions that don't need it
