Solution 1Recommended

Check Your Apple iCloud Storage Settings

Identify what is consuming your iCloud space, as Microsoft 365's OneDrive storage is separate and does not expand your Apple iCloud capacity.

Microsoft 365 includes up to 1 TB of OneDrive storage. However, iCloud is Apple's independent cloud storage service. Purchasing a Microsoft 365 subscription does not increase your iCloud storage or manage Apple device backups.

To resolve the iCloud warning, you need to manage your Apple account storage directly from your device settings.

Open System Settings

Launch the Settings app on your iPhone, iPad, or Mac device.

Access Apple ID Profile

Tap or click on your Apple ID name located at the very top of the Settings menu.

Navigate to iCloud Management

Select 'iCloud', then choose 'Manage Account Storage' or 'Manage Storage' to view a breakdown of what is using your space.

Free Up Space or Upgrade

Delete unneeded backups, photos, or files to free up space. If you need more iCloud storage natively, you must purchase a larger storage plan directly from Apple.

Check Your Apple iCloud Storage Settings

Independent Cloud Services: Your 1 TB of OneDrive space is still available for your documents and files. You can manually move large files like photos to the OneDrive app to free up iCloud space.

Frequently Asked Questions

Can I use my Microsoft 365 OneDrive storage for automatic Apple device backups?

No, Apple devices natively use iCloud for full device backups (like app data and system settings). However, you can use the Microsoft OneDrive app to back up your photo library automatically by enabling the 'Camera Upload' feature.

How do I move files from iCloud to OneDrive to clear the warning?

You can open the Files app on your Apple device, navigate to your iCloud Drive, select the large files you want to move, and copy them to the OneDrive folder. Once they are safely synced to OneDrive, you can delete the originals from iCloud.

Does WPS Office require OneDrive or iCloud to save files?

No. WPS Office gives you full control over where you save your files. You can save them directly to your device's local storage, or link the app to third-party cloud services like Google Drive, Dropbox, OneDrive, or iCloud Drive based on your storage availability.
