I am responding to an email where another person is asking about when I will be available next week?. Now, I am not yet sure about my next week schedule. It depends on couple of important must-have meetings which are not scheduled yet. I wrote following response:
Right now, I am not certain about my next week schedule. It depends on couple of must-to-attend but yet-unscheduled meetings. I will send you a follow-up email by end of this week about my availability.
Can you please suggest some better way to describe it?
