You work as the Enterprise Exchange Administrator at ABC.com. ABC.com is using
Microsoft Exchange Server 2010 as their messaging solution.
How can you configure Outlook Web App (OWA) to block ABC.com employees changing
passwords?

A.
You must use IP Block list.

B.
You must change the properties of the OWA virtual directory.

C.
You must use an Outlook Web App mailbox policy.

D.
You must set up recipient filtering.

Explanation:
This question is confusing as two answers are correct. If you wish to disable the changing of
passwords through OWA for all domain users, then you would use the following command:
Set-OwaVirtualDirectory -Identity <OWAVirtualDirectoryName> -ChangePasswordEnabled
$false However, if you wish to prevent certain users from changing their passwords through
OWA, then you use the Segmentation tab of the OWA mailbox policy in the EMC. Or,
alternatively, you could use the following command:
New-OWAMailboxPolicy -Name ‘OWA Mailbox Policy Name’ | Set-OWAMailboxPolicy –
ChangePasswordEnabled $false
I have gone for the former answer as it does not specify that it should only be configured for
certain individual users.
