How to AD query of users with OWA enabled

[Wong@discussions.microsoft.com Terence Wong]

I've tried to select any options by Active Directory Users and Computers but
no suitable option was found

Hi
this is stored in the attribute "protocolSettings" of each user.

The way to query it depends on the Exchange version
Exchnage 2003:
something like
(&(objectClass=user)(homeMDB=*)
(|(protocolSettings:HTTP§1§1§§§§§§)(protocolSettings=HTTP§1§0§§§§§§)
(!(protocolSettings=*)
)
)

Exchange 2007:
get-casmailbox | where-object {$_.OWAEnabled -eq $TRUE}
