Selecting User Initiated Password Changes in Common Application Settings allows users to set their Mimecast cloud Password in which of the following?

Choosing the option that states users can set their Mimecast cloud password in the Mimecast Personal Portal is accurate because the Personal Portal is designed as a user interface that provides individuals with the ability to manage their account settings, including password management. This portal is specifically intended for users to interact with their Mimecast account in a secure manner, allowing them to change passwords and adjust other personal settings as needed.

The other options do have functionalities related to Mimecast services but do not provide a venue for setting passwords directly. Mimecast for Outlook, Mimecast Mobile, and Mimecast for Mac focus mainly on accessing and using Mimecast’s services rather than providing account management features like password changes. Thus, the correct answer correctly points to the most appropriate place where users have the capability to initiate password changes.
