I cannot set up scan to email on Smart Tank 7602

[gooddad56]

We are actually on iOS Sequoia 15, using Office 365 for most of our work. We have an HP Smart Tank 7602 set up to a MAC-Mini via wireless connection. While being logged in to the EWS for this printer, I have been trying many different settings to enable scan to email, but I get a couple of error messages:

"SMTP server busy, try again later"

"Incorrect credentials, check username and password"

Outgoing server settings: smtp.office365.com    Port 587

With and without Server Authentication

email account being used on the Mini: shipping@companyname.com

Account type: Exchange

I can't seem to figure out what I am missing.  Thanks

@gooddad56, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

Setting up Scan to Email on the HP Smart Tank 7602 using Office 365 (smtp.office365.com) can be tricky due to strict Microsoft security requirements. Based on your details, here’s a step-by-step guide and what might be going wrong:

Checklist of Key Requirements

SMTP Server: smtp.office365.com

Port: 587

Encryption: STARTTLS (also known as TLS)

Authentication: Required (Use full email address and correct password)

Username: Your username

Password: App password (if MFA is enabled)

Sender Email: Must match the username

Likely Causes of Your Errors

Error 1: "SMTP server busy, try again later"

• Could be a timeout, incorrect port, firewall, or incorrect encryption setting.
• Ensure STARTTLS is selected, not SSL or no encryption.
• Double-check that port 587 is open on your network.

Error 2: "Incorrect credentials, check username and password"

• If you're using Multi-Factor Authentication (MFA) on the Office 365 account, you'll need an App Password — regular password will fail.
• Go to Microsoft 365 admin > Account Settings > Security Info > Create an app password.

Recommended Configuration in HP EWS

• Open HP EWS in your browser.
• Go to Scan > Scan to Email > Outgoing Email Profiles.
• Choose to Add or Edit the email profile.
• Use these settings:

1. SMTP Server: smtp.office365.com
2. Port: 587
3. Use STARTTLS: Yes
4. SMTP Authentication: Yes 
   Username: Enter the user name
   Password: [Use an App Password if MFA is enabled]
5. Sender Email Address: Enter the email address

• Save settings.
• Use Test or try scanning a document to that email.

Troubleshooting Tips

• Create App Password: https://account.microsoft.com/security
• If using Exchange-based account, ensure SMTP is allowed for that mailbox: 
  Admin must enable SMTP AUTH for that user in Microsoft 365 admin center.
  Go to Users > Active users > [your user] > Mail > Mail apps > Enable SMTP AUTH.
• Firewall/Router: Ensure port 587 is open and not blocked by your ISP or firewall.
• EWS Timeouts: If the interface is idle, refresh and try again.
• Test with Another Email: Temporarily test with a Gmail account (with App Password).

Optional Debug Step: Enable SMTP Logging

If all fails, some HP printers support SMTP logging. Look under:

• EWS > Settings > Administrator Settings or Diagnostics
• Enable logging and try a scan-to-email. Review the logs for SMTP handshake errors.

I hope this helps. 

Take care and have a good day.
