The following parameter can be added to the MNE Global Default Settings under the [General] section so that MNE will not apply any permissions to the target mailbox.
This setting tells the wizard to not manipulate ACLs in any way during the migration. By default (ACLs=1) the wizard will
copy ACL information and will set folder permissions in Exchange. New in version 4.10: The ACLs parameter now
also determines whether PAB ACLs will be migrated. Prior to this enhancement, PAB ACLs were always migrated
regardless of this ACLs=<#> setting.
