Hi Ex Team,

EM is another good step to make the system more secure until the patches can be applied. Perfect!

The_Exchange_Team But why do the applied mitigations have to be removed manually? Why is there no property called "MitigationOutdated" on the ExchangeServer. Each SU and CU could enter here the mitigation that was previously applied and now fixed. And with a script you could remove all MitigationOutdated like

remove-mitigation $(get-ExchangeServer).MitigationOutdated

to revert the mitigation configuration.
