[General] How to ask if a person has come back ? (politely)

[ken_oy]

I have to meet my graduate school professor whom I haven't met for a long time. I emailed him to schedule an appointment, but he went for vacation. He told me he would be back this week. I am still not sure whether he is back today, how to write in email to ask politely? Thanks.

Dear Professor XXX

I just wondered if you are back from your vacation yet. Please let me know when you return so we can arrange to meet up.

Thanks.
