This field isn't used directly from the Active Directory system for any technical function. Needless to say that it is indeed an important info attribute when it is provided to other users in global address lists or stuff like that. This is the reason for having the mail attribute in the global catalog by defaul.
For users with an Exchange mailbox the real recipient addresses for email are stored in the multivalue attriobute proxyAddresses. When proxyAddresses is changed manually with admin tools or by a recipient policy, the systems sets automatically the the value of attribute mail to the primary SMTP address.This is not the case when you set the attribut by script or with programming technics - therefor in Exchange environments the following rule is valid:
- The attributes "mail" and "proyAddresses" are to be set together. The value of "mail" has to be the primary SMTP address from "proxyAddresses".
