DepEd Gmail Not Receiving Emails – Storage Quota Full

Since Google's 2024–2025 storage policy changes, many DepEd accounts hit quotas quickly (Gmail + Drive + Photos shared pool). When storage is full, **new incoming emails bounce** or fail silently (senders may see "mailbox unavailable" or 552/Quota exceeded bounce).

Symptoms:
- No new mail arrives (but old mail visible)
- Senders report delivery failure
- Storage at 100% in one.google.com

Steps to fix:

1. Check usage immediately
- Go to https://one.google.com/storage/management
- See Gmail vs Drive vs Photos breakdown (Photos auto-backup often culprit)

2. Free space urgently
- Empty Trash & Spam folders in Gmail (they count toward quota)
- Delete large attachments: Search Gmail for `has:attachment larger:10M` → delete unnecessary
- Turn off Google Photos backup: photos.google.com → Settings → Backup → Off (or set to High quality)
- Clean Drive: drive.google.com → Storage tab → Sort by quota used → Delete old modules/photos

3. DepEd-specific notes
- New teachers: Wait 2–5 days after HR activation before heavy use
- Shared Drives (school/division) don't count toward personal quota – move shared resources there
- If quota still blocked: Submit helpdesk ticket to division ITO/MIS (they may request temporary lift or pooled adjustment per DepEd policy)

4. Prevention
- Enable auto-delete for Spam/Trash older than 30 days (Gmail Settings → Filters)
- Regularly archive old emails to Drive as .mbox (export via Takeout)
- Monitor storage monthly

After cleanup, emails should resume within minutes–hours. If not, check MX records via admin console (rare misconfig) or report outage on workspace status dashboard.

Still no mail after freeing >10% space? Create ticket with screenshot of storage page + recent bounce message (if sender shares).
