Problem with Windows Desktop Search

We have a 2012 R2 terminal server running at a virtual server. Installed on the TS is office 2013 with outlook configured for remotely hosted email.  Connecting to the hosted mail with Exchange Proxy settings using NTLM authentication. The OST files are on a data drive on the TS which is configured to be searched by WDS.  But you can never successfully search for anything in your mail.

Using a very small test outlook account, with In outlook under search status, there is always 10 items to be index.  It never falls even when checking under  "index options" shows there are 1,120,000 items already index and the count has stopped.

rebuild has been hit many times

uninstalling WDS and re installing has been attempted many times.

Under files types to be index both PST and OST are ticked with Index and file contents selected ALTHOUGH they are considered "Plain Text Filtering." MSG is also ticked and a considered outlook office MSG IFilter.

One completely random item I feel might point to the problem.  With outlook is closed, going into index options through control panel, looking at included locations,  you see Microsoft Outlook with the 2013 icon ticked.  Clicking modify also shows you Office Outlook with the correct 2013 Icon. Plus you see the data drive and ie history also ticked but this is irrelevant.

When you open outlook 2013, select Options, Search , Index Options  -  Office outlook has vanished! When you click modify you find mapi15:// followed by a SID, when this entry is highlighted, a balloon says  "This location is currently unavailable, uncheck it blah blah blah."

When you close Outlook 2013 and once again go into Index options everything looks normal with Office Outlook once again showing nicely in both screens.

I would like to be able to configure WDS to search the OST file on the data drive.

Can anyone help please
