      4. Use the filters to search for the missing email (like sender, subject, or date).
      5. If you find the email, check why it was quarantined and decide whether to release it or mark it as safe.
  2. Blocked Sender:

    • Issue: Not receiving emails from specific senders because they are blocked.
    • How to Fix:
      1. Check your Outlook email client for the blocked sender list.
      2. In Outlook, go to "Settings" and click "View all Outlook settings."
      3. Navigate to "Mail," then "Junk email."
      4. Look under "Blocked senders and domains" for the sender's email address.
      5. If the sender is blocked, remove them to start receiving their emails again.
  3. Adding Safe Sender:

    • Issue: Emails from some senders are marked as spam or junk and don't reach your inbox.
    • How to Fix:
      1. Open your Outlook email client and go to "Settings."
      2. Click "View all Outlook settings," then "Mail."
      3. Select "Junk email" and go to "Safe senders and domains."
      4. Add the sender’s email address to the safe sender list.
      5. Save the changes to ensure future emails from this sender land in your inbox.
  4. Email Not Delivered:

      2. Review any settings for outgoing and incoming email filtering.
      3. Ensure the email queue isn’t backed up.
      4. Reach out to your email service provider for further assistance if delays continue.
  6. Missing Emails Due to Focused Inbox:

    • Issue: Important emails might be missed because they are filtered by the Focused Inbox feature.
    • How to Fix:
      1. In Outlook, go to "Settings" and click "View all Outlook settings."
      2. Select "Mail," then "Layout."
      3. Find "Focused Inbox" and either turn it off or adjust the settings to make sure you don’t miss important emails.
      4. Check the "Other" tab frequently to see if any important emails were misclassified.
