When you access an archived mailbox you have a number of options available to you in terms of finding and accessing user data.
Live and Archive View
Administrators can switch between the 'live view' and 'archive view' of a users mailbox - much like an end user can within the Mimecast Personal Portal.
Browse through the folder structure (live or archive view) much like you do within Outlook or any other email client.
There are two options for search. Searching for folder names across the mailbox (including mail, calendar and contact folders) and searching for content within specific folders.
Use the search field above the folder list to search across all mailbox folders.
Once you have selected a folder from the list and loaded the content, you can search within that folder using the search field above the list of emails, calendars and contacts (dependent on what folder you have loaded.)
NOTE: When searching email folders, a full content search across message body, subject and attachments is performed.
NOTE: At this time, searching calendar and contact folders is meta data only.
Searching calendar folders: a search across the organizer, attendee and subject only.
Searching contact folders: a search across name, email address and company only.
