The calendar reminder does not alert the user when its supposed to. It should provide the alert no matter what tab you are in or whether the browser is up. Previously we used to have mail alerts in the Yahoo Toolbar. Is there a browser extension (.crx, .xpi, .exe) we could add that allow users to get the calendar reminders even if they do not have the Yahoo Mail page open?
Reminder for Corp calendar account are managed by exchange thats why you don’t see those options for your corp calendar account. You should still be able to see these options for your personal Yahoo calendar account. Thanks, Ashish
