Is it possible to run Merge Contact and Mailbox Enable and not have the checkbox "Automatically update e-mail addresses based on e-mail address policy" checked?
The reason for this requirement is that a customer wants to have the primary email address transferred over from Domino "as is".
This scenario is achievable using the follow parameter in the Global Defaults file:
This setting determines whether the Wizard should, after mailbox-creation, set the newly created mailboxes to Automatically update e-mail addresses based on e-mail address policy. This is an Exchange feature offered in the Exchange Management Console, as a checkbox on the E-Mail Addresses tab of the Data Properties for each mailbox. This NME parameter specifies whether the Wizard should automatically enable or disable that Exchange feature during mailbox-creation.
For example, the default:
… tells the Wizard to enable the Exchange automatic-update feature (check the Exchange checkbox).
To disable the Exchange feature (uncheck the Exchange checkbox), set EmailAddressPolicyEnabled=0.
