Stop Automatic Camera Uploads on Android
Disable the automatic backup of photos and videos on your Android device to prevent OneDrive from filling up your shared Microsoft storage.
If your Microsoft storage is maxed out, it is often due to automatic media backups from a mobile device. Disabling this feature ensures your storage isn't consumed by large video and photo files.
Open the OneDrive app on your Android device. Tap on the 'Me' icon or your profile picture at the bottom right, then select 'Settings'.
In the Settings menu, tap on 'Camera upload'.
Toggle off the 'Camera upload' switch. If prompted, confirm that you want to stop backing up your photos and videos.
If you are using a Samsung device and cannot find the OneDrive app, go to your phone's Settings > Accounts and backup > Manage accounts. Select your Samsung account, go to 'Sync apps', and toggle off the OneDrive sync for Gallery.
Unlink OneDrive from Your PC
Disconnect your computer from OneDrive to stop large desktop files from automatically syncing to the cloud.

Frequently Asked Questions
Why does my OneDrive storage limit prevent Outlook from sending emails?
Microsoft utilizes a unified storage quota for your entire Microsoft account. This means OneDrive files, Outlook email attachments, and Microsoft 365 apps all share the same storage space. When OneDrive is full, your email service is blocked.
Will I lose my photos if I stop the OneDrive backup on my Android phone?
No. Disabling the camera upload feature only stops future photos from uploading to your Microsoft cloud account. All existing photos remain safely stored in your phone's local memory.
How can I stop the backup if I don't see the OneDrive app on my Android device?
If you cannot find the standalone OneDrive app, your phone might be syncing via a built-in integration, such as Samsung Gallery. Check your device settings under 'Accounts and Backup', locate your Microsoft or Samsung account, and disable the cloud sync options from there.
How long does it take for Outlook to start working again after I free up storage?
Once you bring your storage under the quota limit, it can take up to 24 hours for Microsoft's servers to update your status and restore your ability to send and receive emails in Outlook.
