outlook not sending email from my shaw account

Hello KIM SCOLES, 

Thank you for reaching out. I understand how frustrating it is when your emails remain stuck in the Outbox. 

First, may I ask if you’ve already checked the suggested solution from Q&A Assist, and whether it helped resolve the issue? 

If not, please try sending an email using Apple Mail or Shaw Webmail. 

• If emails send successfully there but not in Outlook, this confirms the issue is isolated to Outlook for Mac. 

In this case, the problem is usually caused by incorrect outgoing (SMTP) settings or a corrupted Outlook profile. 

• Please remove your Shaw email account from Outlook and add it again, making sure the SMTP settings are correct. 

If re-adding the account doesn’t help, follow these steps to reset your Outlook profile: 

•  Quit Outlook. 
• Open Finder > Applications. Right-click Microsoft Outlook and select Show Package Contents. 
• Open Contents > SharedSupport and double-click Outlook Profile Manager. 
• Click the + button to create a new profile. 
• Highlight the new profile, click the gear icon, and select Set as Default. 
• Open Outlook. 
• Go to Outlook > Settings > Accounts and add the Shaw email account. 
• Send a test email to confirm the Outbox is working. 

Finally, send a test email to test that messages are no longer stuck in the Outbox. 

Should the issue continue, please share the outcome of the test email and any additional details, so we can further investigate and assist you accordingly. 

Use the following checks and changes in Outlook for Mac to resolve Shaw mail stuck in the Outbox.

1. Confirm Outlook and network connectivity

• In Outlook for Mac, on the Outlook menu, make sure Work Offline is not checked.
• Use a browser on the Mac to open any website to confirm the Mac is online.

2. Check mailbox/storage limits

• If using a Microsoft account in the same profile, verify that Microsoft cloud storage is not full. If storage is full, sending can be blocked until space is freed. See the mailbox storage page linked from the article if applicable.

3. Turn on SMTP authentication for the Shaw account Many POP/IMAP providers (including ISPs like Shaw) require authentication on the outgoing (SMTP) server.
4. In Outlook for Mac, go to Tools > Accounts.
5. Select the Shaw account in the left pane.
6. Under Outgoing server, click More Options.
7. In the pop-up, choose the appropriate authentication type (typically the same username/password as the incoming server) and enter the Shaw email credentials.
8. Save and try sending again.
9. Verify Shaw server settings and credentials If messages still hang:
10. Go to Tools > Accounts again.
11. Select the Shaw account and verify:
    • Email address, username, and password are correct.
    • Incoming and outgoing server names and ports match the values Shaw requires (check Shaw’s documentation or support site for exact POP/IMAP/SMTP, SSL, and port settings).
12. If Shaw requires SSL or non‑default ports, enable SSL and set the ports exactly as specified by Shaw.
13. Check for firewall or network blocking SMTP If the Mac is on a home or work network that blocks SMTP:
14. Ask the ISP or network admin whether outbound SMTP ports used by Shaw (for example 587 or 465, depending on Shaw’s settings) are blocked.
15. If they provide an alternate SMTP server or port, update it in Tools > Accounts > select Shaw account > Outgoing server.
16. Confirm the Shaw mail server is available If this account worked previously and suddenly stopped, the Shaw mail server may be temporarily unavailable. Contact Shaw again specifically to confirm server status and that the mailbox is not locked or over quota.
17. Check attachment size and Drafts/Outbox

• Large attachments can prevent sending. Open the stuck message in the Outbox and remove large attachments, then send again.
• If Outlook shows an error that the message is too large, move or delete the message from Drafts or Outbox and then permanently delete it from Trash.

If, after verifying SMTP authentication, Shaw’s exact server settings, and network/firewall status, messages still hang in the Outbox, create a new Outlook profile and re-add only the Shaw account to test sending in a clean profile.
