You could create a custom inventory rule (this article , maybe  RegistryValueEquals) and search for the following in the registry:

1. Start > Run > Regedit
2. Expand HKEY_LOCAL_MACHINE\Software\Microsoft\Office\xx.y\Outlook where xx.y is a version number, typically 10.0 through 20.0.  If this key does not exist then it is likely registered under Wow6432Node, which means it is a 32-bit version.
3. Look at the value in the key called Bitness.  This value should be either x86 (32-bit) or x64 (64-bit).

hope this helps
