"Error: [7302-54-09-00000000] Unable to add group member user@domain to list@domain" (4303326)

When migrating users in a group, NME was unable to find a member of the list using the smtp address for the user with the following error:

Error: [7302-54-09-00000000] Unable to add group member user@domain to list@domain.

NME was unable to find the member of the list using the SMTP address for the user. In order to be added to a list, the user must be a mail-enabled security object or a mail-enabled contact with the address listed as the primary SMTP address or listed as a proxyAddress.

You can either add the user and then provision groups a second time or you can ignore this error if the user will not be added to AD.

If the user will be migrated later, then you can provision groups to add this user to the list after the user is migrated.
