I must have inadvertently disabled notifications and reminders in my Outlook.com calendar because when I view the details of any event in the calendar, it says "You've turned off your calendar notifications (reminders, changes to calendars, and daily summaries). Turn them back on" under the "Reminders" section of the event details page. When I click on the "Turn them back on" link, I am redirected to the calendar options page. When I try to click on the box next to "Get notifications (reminders, changes to calendars, and daily summaries)" under the "Turn notifications on or off" section of the calendar options page, it will not let me click on that box to re-enable the calendar notifications. That is, the box does not become checked when I click on it. It seems that the checkbox to enable calendar notifications has been disabled. I am aware that Outlook.com is performing maintenance on the calendar. I saw the following announcement, dated October 23, 2013, on the Microsoft services system status page: "Outlook.com is performing maintenance on the calendar. You might see error messages when creating/editing birthdays. The checkbox to get notifications in the Options page may also be disabled during this time. Sorry for the inconvenience." Can someone please tell me if this maintenance is still underway, and, when it will be completed and/or offer some advice on how to re-enable notifications in Outlook.com calendar?
