Again and again questions about how OCS deals with "Content Life Cycle" are reaching me. And it isn't very strange because there is no "very" clear information on how OCS deals with expiration dates etc. Except when you purchase the OCS Resource Kit from Microsoft Press ;-)
Where can you set an expiration date within a meeting? In Live Meeting Console you can't. When using the web scheduler can.
Settings referring to this configuration items are found within the following WMI classes:
The meeting expiration within OCS is out of the box: 14 days you can find a integer ContentExpirationGracePeriod This property type typically describes the grace period in addition to the expire time after which the Web Conferencing should clean up content for a conference.
The maximum lenght of any meeting without any activity is covered in the MaxMeetingLength property. The OOTB value is 24 hours.
The UCAuthenticatedUserGracePeriod property defines the grace period allowed for anonymous or federated users to stay in the meeting without any authenticated user in the meeting.
You can change all values above according to your organizational needs.
The tools to make encrypted meeting content on your server more viewable are included within the OCS Resource Kit (DMInsider, DMHash and DMDel)
