We have several thousand 'contacts' setup in AD already for a faxing system. We're migrating to an online fax provider that uses e-mail rather than plain old telephone. So, we've bulk edited all the AD records so that the 'mail' attribute is populated with the right e-mail address in the right format.
Now, how do we enable these contacts within Exchange 2007? I've looked through http://technet.microsoft.com/en-us/library/bb684891.aspx but that only seems to talk about manually editing the CSV output to specify the external addresses. AD already knows the external e-mail addresses - I just need the info in Exchange!
Any thoughts?

Have a read through of the first link - very helpful.

Maybe you could use ExchMbx but is untested with Exchange 2007
Check out ADModify. It allows bulk change to AD attributes including exchange attributes.
