Setting Outlook Registry setting of type REG_EXPAND_SZ

[TimGoff]

Hi

I am changing users Outlook autosignature by code - first copying a template to their profile and then setting a registry value, which is :

[user sid]\software\microsoft\office\10.0\common\mailsettings.

The value name is NewSignature of type REG_EXPAND_SZ.

I initally thought I could pass the string value of the template and change the value, but Outlook doesn't recognise it.

Any help much appreciated
Tim
