We agreed he was coming over to my country to have a meeting with my manager and myself in a week in March. But we didn't decide specific date, then i asked my manager's assistant to block his schedule of the whole week.
Please comment if this is a proper expression and ket me know if there is better way to communicate. -
Dear Xxx,
Hope you had a great start of the year 2018.
I’m wondering if you might be able to narrow the date to come over, as my manager's assistant is receiving meeting requests to him in March and getting difficult to find right time excluding this whole week.
I’d be also glad if you could let us know your intention how many days you’d like to spend for the discussion.
