Under Exchange 2007 we had a journal mailbox. It was really simple to set up MRM to remove entries under the calendar from this journal mailbox every day. In 2010 SP1 it appears that this isn't possible? Can anyone confirm this? When setting up a retention policy, there is no option to select "Calendar". It just lists inbox, journal, spam, deleted items, etc. Is this an oversight or am I missing something? All I need to do under 2010 is set up a policy that removes calendar items from a single mailbox every 24 hours. Can anyone advise? I have performed the following in the EMS but cannot see a way to "apply" this to a mailbox? New-ManagedFolder -Name 'Journal Mailbox Calendar' -DefaultFolderType Calendar New-ManagedContentSettings -Name 'Delete Journal Mailbox Calendar Entries' -FolderName 'Journal Mailbox Calendar' -MessageClass Calendar -RetentionEnabled $true -TriggerForRetention WhenDelivered -RetentionAction PermanentlyDelete -AgeLimitForRetention 1 I have tried running Set-Mailbox -Identity JournalMB -ManagedFolderMailboxPolicy 'Journal Mailbox Calendar' but this throws an error: The managed folder mailbox policy "Journal Mailbox Calendar" How do you apply the managed folder to a user?

OK I think I figured this out. Is this correct in that there are four stages required? New-ManagedFolder -Name 'Journal Mailbox Calendar' -DefaultFolderType Calendar New-ManagedContentSettings -Name 'Delete Journal Mailbox Calendar Entries' -FolderName 'Journal Mailbox Calendar' -MessageClass Calendar -RetentionEnabled $true -TriggerForRetention WhenDelivered -RetentionAction PermanentlyDelete -AgeLimitForRetention 1 New-ManagedFolderMailboxPolicy -Name 'Delete Journal Mailbox Calendar Entries' -ManagedFolderLinks 'Journal Mailbox Calendar' Set-Mailbox -Identity JournalMB -ManagedFolderMailboxPolicy 'Delete Journal Mailbox Calendar Entries'
