Office 365 - Resolution for Bad Outbound Senders

What Is This Issue and How It Helps

SmartReach.io pauses campaigns when Microsoft Outlook rejects emails with the "Access denied, bad outbound sender" error to protect your email reputation. This ensures your cold email outreach remains effective by preventing further damage to your sender credibility.

How It Works

SmartReach.io monitors your sent emails and analyzes bounce messages from your email provider. If Microsoft Outlook flags your emails with the "Access denied, bad outbound sender" error, the platform automatically pauses the affected campaigns. Below are the steps to identify and resolve this issue, as well as how to resume your campaigns.

A: Steps to Resolve the Issue

1. Check for Restricted User Status
2. Visit Microsoft’s Restricted Users page to see if your account is restricted.
3. Log in to Microsoft 365 Security or review Microsoft’s documentation.
4. Contact your email account admin (or do this yourself if you’re the admin) to remove your account from the restricted users list.

B: Enable Authenticated SMTP

1. Ensure Authenticated SMTP is active for your Microsoft account, as this is required for sending emails through SmartReach.io.
2. For Microsoft 365 accounts purchased directly: Follow [Microsoft’s SMTP setup guide.](Microsoft accounts purchased directly through Microsoft 365)
3. For accounts purchased via GoDaddy: Refer to [GoDaddy’s SMTP setup guide.](Mircrosoft Accounts purchased via GoDaddy)

C: Improve Email Deliverability

1. Check if your emails are landing in spam folders. If 1% or more of recipients previously marked your emails as spam, this can trigger rejections.
2. Write short, personalized emails to increase engagement.
3. Include an unsubscribe link in all emails to comply with best practices and reduce spam complaints.

Verify Resolution

1. After addressing the above steps, test your email account by sending a single email through SmartReach.io to confirm it’s no longer rejected.
2. If the issue persists, contact SmartReach.io support via the support page or book a call.

How to Prevent Future Pauses

• Regularly monitor your email deliverability using SmartReach.io’s spam and authentication checks.
• Keep your email content concise and tailored to your audience.
• Ensure Authenticated SMTP remains enabled and your account is not restricted.
