Saveset ID: 201412299889600~201302192124210000~Z~E0BABA40E9FE4E446A7F9ED1839232C1

Indicators the the issue may be present are as follows:

1. Exchange "Recoverable Items\Versions" folder consumes a large amount of space on the Exchange Servers.
2. The Exchange "Recoverable Items\Versions" (not visible to users) folders contain large quantities of duplicate Recurring Custom Calendar items, modified by the Vault Service Account.
3. Calendars in Enterprise Vault Users' Archives contain large quantities of duplicate Recurring Custom Calendar items, corresponding to the duplicate items within Exchange "Recoverable Items\Versions" folder.

A Dtrace of ArchiveTask will contain a "0x8004010f" MAPI_E_NOT_FOUND error code during post processing.
{DELATTACHFROMMSGANDAPPENDLIST.EN_US} HRXEX fn trace : Returning error [0x8004010f]

Steps to confirm issue

1. Examine the calendar in the user's archive for multiple copies of Recurring Custom Calendar items.
2. Start a DTrace on the ArchiveTask process
3. Execute a "Run Now" for "Archiving and Shortcut Processing" against the affected user's mailbox
4. Allow the "Run Now" to complete
5. If the Vault Store's "Safety Copies" setting is configured for "After backup", run a backup of Enterprise Vault.
6. Wait for the "Storage File Watch" process completion event for all partitions of the Vault Store containing the user's archive.  The end of the "Watch file partition scan" is indicated by an Event from the "Storage File Watch" process in the Symantec Enterprise Vault Event Log.
7. Allow an additional 10 minutes for the Archive Task to finish post-processing
8. Stop the DTrace
9. Examine the DTrace for error lines containing 
   "{DELATTACHFROMMSGANDAPPENDLIST.EN_US} HRXEX fn trace : Returning error [0x8004010f]"

If the above conditions are present, then it is likely that the issue is present within the environment.  

In Exchange 2010 and above, when a single occurrence of a Recurring Custom Calendar Item is edited, it is stored as an attachment to the original Recurring Calendar Item.  During Post Processing of an Recurring Custom Calendar item, with at least one Edited Single recurrence, the archiving task attempts to strip attachments from the Edited Occurrence.  If the Edited Occurrence is missing the MAPI Attributes PR_BODY, PR_HTML, or PR_RTF_COMPRESSED Post Processing may fail with "0x8004010f" MAPI_E_NOT_FOUND.  During the next archiving run, the item is seen as a new item and is re-archived.  This in turn causes the Exchange item to be placed in the Exchange "Recoverable Items\Versions" folder repeatedly.
