Exchange 2013 CU3 Retention Policy Not working for Calendar & Tasks

Question

We are currently on Exchange 2013 CU3 with Online Archiving Enabled for the user
Default policy is set to move  all the items in mailbox which are  older than 30 days to online archive mailbox.
Calendar and Tasks Items are also getting archived alongwith other Outlook items from Inbox,Deleted Items etc
Followed Technet website and created RPT for Calendar and Tasks with retention disabled
Still DPT takes precedence and move all the items under Calendar and Task to Online Archive Mailbox

Hi Sam,
I recommend you refer to the following article, despite this for Exchange 2010, however the same applies to exhcnage 2013:
Prevent archiving of items in a default folder in Exchange 2010
To prevent the <acronym title="Default Policy Tag">DPT</acronym> from being applied to a default folder, you can create a disabled <acronym title="Retention Policy Tag">RPT</acronym> for that folder (or disable
any existing RPT for that folder). The Managed Folder Assistant, a mailbox assistant that processes mailbox items and applies retention policies, does not apply the
retention action of a disabled tag. Since the item/folder still has a tag, it's not considered untagged and the DPT isn't applied to it.
Why are items in the Notes folder still archived?
If you create a disabled <acronym title="Retention Policy Tag">RPT</acronym> for the
Notes folder, you'll see items in that folder are not deleted, but they do continue to be moved to the archive! Why does this happen? How do you prevent it?
It's important to understand that:
A retention policy can have a <acronym title="Default Policy Tag">DPT</acronym> to
archive items (using the Move to Archive retention action) and a DPT to
delete items (using the Delete and Allow Recovery or
Permanently Delete retention actions). Both apply to untagged items.
The move and delete actions are exclusive of each other. Mailbox folders and messages can have both types of tags applied - an archive tag and a delete tag. It's not an either/or proposition.
If you create a disabled RPT for the Notes folder to not delete items, the archive DPT for the mailbox would still apply and move items.
When it comes to archiving, there's only one archive policy that administrators can enforce – the <acronym title="Default Policy Tag">DPT</acronym> with 'Move to archive' action.
You can't create a <acronym title="Retention Policy Tag">RPT</acronym> with the 'Move to archive' action. This rules out using the disabled RPT approach to prevent items from being moved.
