Different Age Based Archiving Rules for Folders in the same Mailbox

Following up on a previous post (https://www-secure.symantec.com/connect/forums/evp...). We currently archive Exchange mailboxes, specified message classes over 90 days old. This works as expected.

I'd now like to add Calendar items over 2 years old, I don't think this is easily achievable using the standard policies and settings. To test this out I have created a new mailbox policy including IPM.Appointment items and applied this to my test mailbox. So far so good.

I then used the below EVPM INI file to set the age based archive policy on the Calendar folder:

[Directory] 
DirectoryComputerName = EVARC-EM1-01
SiteName = Enterprise Vault - EM

[Filter]
Name = 2YearCalendar
CreateShortcut = False
DeleteOriginal = True
UnreadMail = True
UseInactivityPeriod = True
InactivityUnits = Months
InactivityPeriod = 24

[Mailbox]
DistinguishedName = LegacyExchnageDN of target mailbox

[Folder]
Name = Calendar
FilterName = 2YearCalendar
OverrideArchiveLocks = True

EVPM processed successfully. I ran provisioning and mailbox synchronisation and tried a Run Now archive, but no calendar items are archived.

Is there a way to verify the policy is applied to the test mailbox? and any ideas on achieving the differing age based archiving on different folders.

Thanks,
