Amazon has been improving Alexa’s diary-managing skills for a while now, adding support for Outlook and iCloud in 2017. This made it easy to ask Alexa to put a meeting in your calendar on a set time and day. Just say: “Alexa, schedule a meeting for 2pm tomorrow afternoon.”
Starting this week, Alexa is now able to edit these arrangements too. You can say: “Alexa, rearrange my meeting” and the assistant will ask for more details about which one, and when to move it to.
You can also say: “Alexa, move my 9am meeting to tomorrow at 2pm” and the change will be made, appearing right away in the calendar on your computer, smartphone or wherever you view it.
