Support for PST in Network Drives

One of the main challenges on VDI has always been around use of Outlook PST’s.Although PST’s are meant to be used as archiving or backup solutions , Smaller mail box size in large Organizations meant that People use PST all the time. I would not like to get into a discussion if one should use PST or not. As a VDI administrator ,  I might be against the use of PST’s but then decision varies from Organization to Organization and we have to live with it. PST’s are generally stored on Home drives ( Data Drive) that are presented to a User in a VDI session. Predominantly , Home Drives are carved out of NAS or on a more generic term “Network Drives”.  Until now , PST’s accessed over Network was not a supported Microsoft Configuration  which meant that you cannot log a case with Microsoft for any issues pertaining to use of PST’s on Network Drives.

Starting with Outlook 2010 , Microsoft has termed that “Network access of PST and OST as a Supported configuration” under specific conditions namely,

  • A high bandwidth/low latency network connection is used.
  • There is single client access per file (one Outlook client per .pst).
  • Windows Server 2008 R2 Remote Desktop Session Host (RDSH) and Virtual Desktop Infrastructure (VDI) are used.
This is a welcome change from a VDI Administrator perspective. There are always advantages and disadvantages of using PST on VDI and you would be the best person to judge if it’s suitable to your environment. Sometimes you don’t have a choice !
More details on Support for PST in Network Drives can be found in this Microsoft KB and would recommend reading the Planning Consideration White paper that can be found here.
