Hi, I need to schedule a meeting with Michael for Sunday at 5 pm. 
Of course, may I have your name, please?
My name is John. 
When do you expect the meeting to wrap up?
It should only be two hours, so around 7 pm?
Would you like to note down an optional reason for the meeting?
Yes, have it down as weekly scrum planning. 
Unfortunately Michael is not able to make Sunday @ 5 pm.
Would you like to try scheduling the meeting for a different day or time?
Can you try 2 pm on the same day?

Ok, try 1 pm on the same day.
I'm sorry, I'm sure you're frustrated, but that time is not available either. Would you like to try another time or day?
No that's alright, I'll just have to check my schedule againg. 
Thank you and goodbye.
