Some calendar items in Outlook are not getting archived.

Problem

Some calendar items in Outlook are not getting archived.

Cause

This issue may be caused by the fact that calendar items with additionally invited people have a different message class than standard calendar events.  Calendar events with more than one attendee are considered meetings.

• Normal calendar events have a message class of IPM.Appointment*
   
• Meetings have a message class of IPM.Schedule*
   

By default, Enterprise Vault does not include the message class IPM.Schedule*.

Solution

In order to resolve this issue, add the IPM.Schedule*  message class to Enterprise Vault and enable it in the Exchange archiving policy.

Add the IPM.Schedule* message class to Enterprise Vault:

1. In the Enterprise Vault Administration Console, right-click on Directory on [EV_Server_Name] and select Properties.
    
2. Click on the Exchange Message Classes tab.
    
3. Click on the Add... button.
    
4. In the Class field, enter the message class IPM.Schedule*.
    
5. In the Description field, enter a description like Meeting Requests.
    
6. Click OK to save the message class to the list.
    
7. Click OK again to close the Directory Properties dialog box.

Enable IPM.Schedule*  for archiving in the Exchange Mailbox Policy:

1. In the Enterprise Vault Administration Console, right-click on the specific Exchange Mailbox Policy  to enable IPM.Schedule* and select Properties.
    
2. Click on the Message Classes tab.
    
3. Check the box next to IPM.Schedule*.
    
4. Click OK to save the changes to the Policy.
    
5. Synchronize the mailboxes affected by the policy update.
    

Note: In order to synchronize mailboxes, go to Tasks under the appropriate Enterprise Vault Server in the console, right-click on the Exchange Mailbox Archiving Task for the server the affected users are on and select Properties. On the Synchronization tab, click the Synchronize button.
