I'm looking to create a new Custom Attribute in my Active Directory schema to add for Users.
Which setting is best to support one that will hold personal e-mail addresses?
For example one User may have "firstname.lastname@example.org", but someone else may have two e-mails like "email@example.com" and "firstname.lastname@example.org".
This would be an indexed attribute for future searching/querying.
My AD functional level is Windows 2008 R2. Do not want to use any MS Exchange schema.
