Back in May, Microsoft announced that it would be sunsetting Sunrise Calendar on August 31. When the end-of-life date came around, the company postponed it, saying that it wanted to add more features to the Outlook Mobile apps first.
Today, that day has finally come, as the app will stop working soon (and we'll stop making those horrible sunset puns). As of today, changes to your calendar will no longer sync with the app. If you add something to your calendar in Sunrise, it won't show up on other platforms, and vice versa. Tomorrow, you will be signed out of your account.
All of the changes that you've previously made to your calendar will continue to be available on your preferred platform, such as Gmail, iCloud, or Outlook. As of today though, you may want to switch over to Outlook if you want to continue to have a similar experience.
As Microsoft promised, it is also updating the Outlook apps today with new features. You can find out more about that right here.
Finally, Sunrise said that it would like to thank all of its users for supporting it along its journey:
We’d like to extend a final and massive thank you to all of you who’ve supported us along the way. It’s been a hell of a ride. We really hope you enjoyed those years we spent together as much as we did.
