use Bitrix\Main\Loader;
Loader::includeModule('crm');
$obActivities = CCrmActivity::GetList(
    [],
    [
        'OWNER_TYPE_ID'     => CCrmOwnerType::ResolveID('CONTACT'),
        'COMPLETED' => 'N',
        'CHECK_PERMISSIONS' => 'N'
    ],
    false,
    false,
    [
        'ID'
    ]

while ($arActivity = $obActivities->Fetch()) {
    CCrmActivity::Update(
        $arActivity['ID'],
        [
            'COMPLETED' => 'Y'
        ],
        false
