Can Groupwise Migrator for Exchange synchronize GroupWise public distribution lists member additions in Exchange distribution lists?
If new members are added to the GroupWise public distribution lists, the 'Directory Exporter' will need to be run again. By running the 'Directory Exporter' again, new members to the GroupWise public distribution lists will be found and added to the 'GroupsToProvision.abk' file.
When the 'Provision Distribution Groups' is performed (a second time since the initial run), it first validates whether the target Active Directory Distribution Group exists, and if it does it does not try to recreate but will add new members when there is a match of current mail-enabled or mailbox-enabled Active Directory objects.
If the Active Directory object is indeed found and has a matching attribute value (based upon matching 'proxyAddresses', 'targetAddresses' and 'mail' attributes) found in the 'GroupsToProvision.abk' file, this mail-enabled/mailbox-enabled object will be added as a member to the Active Directory Distribution Group.
