Enable or Disable the Automatic Removal of Older Versions of Meeting Messages

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

By default, the Calendar Attendant removes older versions of meeting messages (such as meeting requests, cancellations, and updates) delivered to recipients' Inboxes. Removing these items helps reduce the number of meeting messages that users have to manage.

When the Calendar Attendant performs this task, the following actions occur:

• Out-of-date meeting updates are deleted.

• Redundant meeting responses that don't contain text are deleted.

• Meeting messages that contain text (for example, responses with additional text or attachments) are preserved.

For example, Tony sends a meeting request to Ayla, and Ayla tentatively accepts the meeting. Tony receives a meeting message stating that Ayla has tentatively accepted the meeting. Ayla later declines the meeting. Tony receives the newer e-mail message stating that Ayla has declined the meeting. The Calendar Attendant moves the older, tentative meeting message into Tony's Deleted Items folder.

For more information about how to disable the automatic removal of older meeting messages on a per-user basis in Microsoft Office Outlook Web App, see "Automatic Processing" in Calendar Tab.
