Adding multiple participant in a single attempt in Outlook calendar event

Question

In the Outlook web mail Calendar event option, If I need to add multiple participants to the event, I can add all of them in the Required attendee section (highlighted in the screenshot), one by one.

Currently I'm not able adding multiple participants at a time. Say if I have to add 20 participants, currently I need to enter the 20 email address separately.

Is it possible, can I add all the participants in a single attempt like adding the email address in semi-colon separated or any other way?

Answer 1

In the recent Outlook, the UI is changed and I can able to paste any number of participants in to the invite attendees field.
