Sara,
Hello, Mr./Ms. Yamada here.
We made an appointment for you to come to the research room next Monday, but actually I was interrupted by an urgent meeting so I couldn't make it.
Sorry, let me change the date and time.
If you want it earlier, tomorrow, the 17th, from 5:00 pm onwards; If it's later than Monday, then I'm free from 10 o'clock on Wednesday and Thursday.
Please let me know your convenient time.
Department of Foreign Languages, 〇X University — Yamada Hana.
