3.8 Set 'Enable OOF messages to remote domains' to 'None'

Information

You can use this setting to determine if the server automatically forwards out-of-office messages to remote domains.

Rationale:

Attackers can use automated messages to determine whether a user is active, in the office, traveling, and so on. An attacker might use this information to conduct other types of attacks.

Solution

To implement the recommended state, execute the following PowerShell cmdlet:

Set-RemoteDomain 'RemoteDomain' -AllowedOOFType None
