Consider the following sentence . My boss (say Mr X) wrote this to me in an email and before this paragraph he actually gave a list of items that I need to work on :
We will have a Webex meeting at 9:00 AM on Friday with Y to review these items. Please confirm that you can make it.
Is he saying that I should be done with those items before 9:00 AM on Friday and then have the meeting with Y or is he just asking me to confirm my availablitiy for that meeting ?
