I have 250.69 storage available, but my calendar is telling me I do not have enough space in cloud?

Hi Thereliable1,

Thank you for participating in the Apple Support Communities. We understand Calendar is prompting an alert that you don't have enough space in iCloud. If you have 250 GB of free space on your device, this is different than iCloud storage space. This article explains the difference between device storage and iCloud storage: What's the difference between device storage and iCloud storage? - Apple Support.

"Device storage is the available storage on your iPhone, iPad, Mac, or other Apple device. iCloud storage keeps your photos, files, notes, and more, up-to-date and available across all your devices.

Device storage

An Apple device like an iPhone, iPad, or Mac comes with a set amount of storage. The more storage your device has, the more music, apps, photos, and other content you can store on that device. If your device storage is almost full or full, you might get an alert.

Here's how to check the amount of device storage you've used and, if needed, how to optimize and manage your storage space.

Check the device storage on your iPhone or iPad

1. Open the Settings app.
2. Tap General.
3. Tap iPhone Storage or iPad Storage to check the amount of device storage that you've used.

If you want to free up storage space on your iPhone or iPad:

2. In the sidebar, click General.
3. Select Storage to check the amount of device storage that you've used.

iCloud storage

To access your content on any device and help optimize your storage, you can also use iCloud storage. You can use iCloud storage to keep photos, videos, device backups, and more, and keep this content up-to-date across your devices. When your iCloud storage is almost full or full, you might get an alert and you can buy more.
