Hi,

When Email Address property for an user is modified, I need to verify
whether this modified email address already exists in the organization.

proxyAddresses property contains all the email addresses of the user.
I found in AD Schema that this property is replicated to GC by default.
my concern here is that this default setting can be modified by an
administrator

Do I perform a single GC Query on proxyAddresses Attribute, to find if
the modified email address already exist in the exchange organization?
or
Do I query a DC of each domain in the forest?

please let me know if there is any other method or workaround

Any help will be appreciated

Regards,
Subodh
