Outlook
stores its account settings etc. in a number of registry keys and
files. When you start up Outlook for the first time, it will check
if these keys exist and, if not, will prompt the user to create a
new account. This works fine in the virtual environment when
Outlook is not installed on the physical system. However, when the
user already has Outlook installed physically, the Thinstalled
version will find the registry keys in the system registry and use
those settings, which is probably not what's intended. What's
needed is "Full Isolation Mode"
for the registry keys and files where Outlook stores its settings,
so the Thinstalled version will pretend the system systems don't
exist. To set this up, some changes need to be made to the capture.
First of all, the following entries need to be added to the
HKEY_CURRENT_USER.txtfile:
must be created in each of the following subdirectories:
%AppData%\Microsoft\AddIns
%AppData%\Microsoft\Office
%AppData%\Microsoft\Outlook
%Local AppData%\Microsoft\FORMS
%Local AppData%\Microsoft\Outlook
(create the subdirectories as needed)
Attachments
By default, Outlook creates a directory where it stores attachments
when you open an attachment for viewing. This directory will
normally be something like "C:\Documents and
Settings\<username>\Local Settings\Temp\Temporary Internet
Files\OLKxxxx" where the last "xxxx" is replaced by something
randomly chosen. This works fine when the viewing application runs
in the same virtual sandbox as Outlook. However, when you want to
use an external application (an application not running in Outlooks
virtual sandbox) the external application won't be able to find the
file it is supposed to show. This is because Outlook will store the
file in the sandbox. To solve this, the isolation mode of the
directory where the attachments are stored needs to be set to
Merged. The next problem then is that we don't know what the name
of that directory is (the last part of the name was randomly
chosen).
To solve this, add a value to HKEY_CURRENT_USER.txt which sets the
name of attachment directory:
isolation_full HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Security
Value=OutlookSecureTempFolder
REG_SZ~%Profile%\Local Settings\OutlookTempxxxx#2300
(The "11.0" in the key name is for Outlook 2003, use the
appropriate version number for your version of Outlook). For
slightly increased security, replace the last 4 "xxxx" characters
by something random.
Next, create a directory "%Profile%\Local Settings\OutlookTempxxxx"
in your project and create an ##Attributes.ini file there
containing:
[Isolation]
DirectoryIsolationMode=Merged
The directory "%Profile%\Local Settings\OutlookTempxxxx" is just an
example, you can use whatever you want, as long as you make sure
that the directory is named in the OutlookSecureTempFolder registry
key and is set to the correct isolation mode.
