correct this if anything wrong

[english_learn]

My colleague is off last two days sick. He usually sends a document to our boss. In his absence, I am not sure whether he has sent it or not. So I decided to send this document with the comment below to the boss. Please correct it if anything wrong.

Attached is the Summary Slide for your update. In Jim’s absence, I am not sure whether you have received it already or not. Thanks
