Why does a Gmail address report being over quota and then start receiving mail again?

Summary

A Gmail address reports being over quota primarily because its 15 GB of free storage is shared across Google Drive and Google Photos. When this combined storage is full, users can't receive new emails. This issue can arise from large attachments, photos, music files, and other data stored in these services. Syncing processes can also temporarily exceed the quota. Resolutions include clearing out large or unnecessary files, emptying the spam and trash folders, or purchasing additional storage through Google One. Once the storage is reduced below the limit, the Gmail address will start receiving mail again.

Key findings

  • Shared Storage: Gmail's storage is shared with Google Drive and Google Photos.
  • 15 GB Limit: The default free storage limit is 15 GB across all three services.
  • Large Attachments: Large attachments, photos, and music files quickly consume storage space.
  • Syncing Issues: Background syncing of large files can temporarily exceed the quota.
  • Hidden Storage: Spam and trash folders can take up significant storage space if not regularly cleared.
  • Storage Solutions: Clearing storage and purchasing Google One storage are effective solutions.

Key considerations

  • Monitor Storage: Regularly monitor storage usage across Gmail, Drive, and Photos to prevent reaching the limit.
  • Clear Files: Periodically clear out large attachments, unnecessary files, and content from the spam and trash folders.
  • Manage Syncing: Be mindful of syncing large files to Google Drive and manage syncing settings.
  • Device Backups: Consider the impact of Android device backups on Google Drive storage.
  • Paid Storage: Evaluate the need for a Google One subscription if the free storage is consistently insufficient.
