To edit an event you first need to select the desired event from the list, then simply click on edit event.
On the edit event screen you will see all the options that were available when creating a new event and you can amend/update any of the details.
After saving any changes to an event you will have the choice to resend the invitation emails to all invitees (In the case the date/time has changed), to just send an email to any added invitees or to not send any email notifications.
Next to each invitee, you also have the option to manually resend the meeting invitation which can be done at any time.
