How to Fix Gmail Not Showing All Emails (IIUM Student/Staff Accounts)

If your IIUM Gmail (Google Workspace) is missing emails, follow these troubleshooting steps:


1. Check the "All Mail" & Other Tabs

Gmail filters emails into categories.

  • Click "All Mail" (left sidebar) – Shows every email, including archived ones.

  • Check Promotions, Social, Updates, Spam tabs.

  • Search for missing emails (use keywords/sender name).


2. Disable Gmail Filters

Filters may auto-archive or delete emails.

  1. Go to ⚙️ Settings → See all settings → Filters and Blocked Addresses.

  2. Delete/disable any suspicious filters.


3. Check "Trash" & "Spam" Folders

  • Trash: Emails deleted in the last 30 days.

  • Spam: False positives may hide here.


4. Increase Gmail Storage

  • IIUM provides 15GB for Google Drive + Gmail.

  • If full, delete old emails or empty "Trash" & "Spam" permanently.


5. Sync Issues? Refresh or Reconnect

  • Browser: Clear cache (Ctrl+Shift+Del) or try incognito mode.

  • Mobile App:

    • Pull down to force sync.

    • Go to Settings → [Your Account] → Sync Gmail.


6. Check Forwarding & POP/IMAP Settings

  1. Go to ⚙️ Settings → Forwarding and POP/IMAP.

  2. Ensure emails aren’t being auto-forwarded or deleted.


7. Try a Different Device or Browser

  • Test on Chrome/Firefox or the Gmail mobile app.


8. Contact IIUM IT Help Desk

If emails are still missing:

Note: IIUM staff/students use Google Workspace, so some features may differ from personal Gmail. 🚀
