Enable native Outlook search experience
With this feature, the Microsoft Outlook offline folder file (*.ost) and the search database specific to the user are roamed along with the user profile.
First, enable Microsoft Windows Search Service, and set its startup type to “Automatic.” Then follow the steps below to enable search index roaming for Outlook.
- Open the Group Policy Management Editor.
- Under Policies > Administrative Templates: Policy definitions (ADM) > Classic Administrative Templates (ADM) > Citrix > Profile Management > Advanced settings, double-click the Enable search index roaming for Outlook policy.
- Select Enabled. Click OK.
If search index roaming is not configured in Group Policy objects, the value from the .ini file is used. If this setting is not configured anywhere, it is enabled by default.
For your changes to take effect, run the gpupdate/force command from the command prompt. You must log off all sessions and then log on again. For details, see http://technet.microsoft.com/en-us/library/bb490983.aspx.
The Enable search index roaming for Outlook feature relies on VHDX files to work. VHDX files are created for each user that uses the feature. VHDX files store user-specific profile on a separate virtual disk that is dedicated to that user’s profile. Profile Management mounts VHDX files on logon and unmounts them on logoff. There are two VHDX files:
- OutlookOST.vhdx file, containing Microsoft Outlook offline folder file (.ost)
- OutlookSearchIndex.vhdx file, containing search index database for the offline folder file stored in the OutlookOST.vhdx file
Quick creation of VHDX files
As an enhancement to the Enable search index roaming for Outlook feature, Profile Management accelerates the creation of user-specific VHDX files. It does so by generating user-specific VHDX files as copies of the template VHDX file (UpmParentVhd.vhdx) that is created automatically when the first user logs on.
For example, if the Enable search index roaming for Outlook feature is enabled, you can see that the following VHDX folder files are available after logon:
- A folder
UpmVhdin the user store. This folder is located in the root folder of the user store. For example, if the user store is configured as
UpmVhd folderwill be created at
- A file
When other users log on, Profile Management generates the VHDX files specific to those users’ profiles as copies of the template VHDX file.
