VDI – Outlook OST caching on a User Profile Disk

Configuring the File Share for Storage of User Profile Disks:

Create a file share with the following NTFS and Share permissions:
In our case : \\fs01.uwsd.loc\UPD

Share Permission

NTFS Permission

Creation of the User Profile Disk Template

To create the UPD Template, you need to execute the following script in PowerShell:
(change the UNC path. The 10 stands for the size of the disk in GB, it’s thin provisioned)

(gwmi -ns root\cimv2\terminalservices -class win32_tssessiondirectory).createuserdisktemplate("\\%SERVERNAME%\%SHARE%",10)
# in our case:
(gwmi -ns root\cimv2\terminalservices -class win32_tssessiondirectory).createuserdisktemplate("\\fs01.uwsd.loc\UPD",10)

Configuratie UvhdRoamingPolicy:

Create a file named: UvhdRoamingPolicy.xml on a central location: In our case \\uwsd.loc\NETLOGON\
In the XML file :

<UvhdRoamingPolicy>
      <RoamingMode>2</RoamingMode>
             <Include>
                     <Folder>AppData\Local\Microsoft\Outlook</Folder>
             </Include>
</UvhdRoamingPolicy>

In the UvhdRoamingPolicy.xml are the folders you want to include. In our case only the Outlook folder

We now need to add the GPO to copy the file from the share to the VDI:
Computer Configuration → Preferences → Windows Settings → Files

Testing:
Log in as a Test user on the VDI. When logged on, you should see the UPD:

Browse to %localappdata%\microsoft and you will see the Outlook icon:

To check the symbolink link:

In the VDI create a Outlook profile and turn on the “Use cached exchange mode” option.

Browse to: %LocalAppData%\Microsoft\Outlook and see the OST file. Logoff and logon to another VDI and see the OST file.
