How to Process Emails Faster office365

Currently, I am using the following approach to search for unread emails in my inbox, and then move them to another folder once they are read.
```php
$messages = $folder->messages()->
                    //all()->//all
                    unseen()-> //unread
                    setFetchOrder("desc")-> //ORDER DESC
                    //limit(1)-> //LIMIT MESSAGE
                    get();
```
