Export not completing from Discovery Accelerator

I am having a similar issue as described in this blog post from 2012.

http://www.symantec.com/connect/forums/export-not-completing

We are running DA on Windows 2012 VM, Enterprise Vault is also running on Windows 2012 VMs seperate from DA and the databases are in SQL 2012.

The messages are on the server but are not converting to .psts.  The version of outlook is 2007.

When I run this query

SELECT tc.[Name] AS 'Case Name', tp.[Name] AS 'Export Name', tp.StatusID, ts.Name AS 'Status', tp.CreateDate AS 'Create Date'
FROM tblProduction tp
JOIN tblCase tc ON tc.CaseID = tp.CaseID
JOIN tblStatus ts ON ts.StatusID = tp.StatusID

The status ID is 51.

I have restarted the Accelerator manager service and even rebooted the server, no luck.

Any help would be much appreciated.
