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.

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

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

Go to ⚙️ Settings → Forwarding and POP/IMAP.

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
