Thanks very much for your help.

We are experiencing an issue with our WordPress site where emails are suddenly not sending. Here are the details:

• Email Source: Elementor Pro
• Mailer: SMTP.com
• Error Message: You must provide at least one recipient email address.

This setup was working perfectly fine before, but now it is giving us this error message. We haven’t made any recent changes to the email configuration or the associated forms.

Steps we’ve tried so far:

1. Double-checked recipient email addresses in forms to ensure they are set correctly.
2. Verified SMTP settings in Elementor and SMTP.com.

Despite these checks, the issue persists. Can you please help us identify the cause of this problem and guide us on how to resolve it?

Thank you for your assistance!

We don’t change the password of the email account, but these are the logs from Easy WP SMTP:

“Error Mailer: Other SMTP SMTP Error: Could not authenticate”

This is what I see when sending a test from Easy SP WMTP:

“There was a problem while sending the test email.

Could not authenticate your SMTP account.

This means we were able to connect to your SMTP host, but were not able to proceed using the email/password in the settings.

Typically this error is returned when the email or password is not correct or is not what the SMTP host is expecting.

Recommended next steps:

1. Triple check your SMTP settings including host address, email, and password If you have recently reset your password you will need to update the settings.
2. Contact your SMTP host to confirm you are using the correct username and password.
3. Verify with your SMTP host that your account has permissions to send emails using outside connections.
4. Visit our documentation for additional tips on how to resolve this error.”

Re-entering the password in Easy WP SMTP -> Settings isn’t enough. We have to change the password in Microsoft 365 and then enter the password in Easy WP SMTP and that would fix it.

This is a recurring problem that pops up about every other month and is unacceptable.

Here are out settings:

Mailer settings: Other SMTP

SMTP Host: smtp.office365.com

Type of encryption: TLS

SMTP Port: 587

SMTP authentication: ON

We would like a solution that doesn’t involve switching the mailer settings to 365/Outlook because that is a Pro feature.

Thank you!

Here the trouble shooting I have done so far:
-Updated all plug-ins
-Installed WP mail logging (shows that the emails get sent and doesn’t log an error)
-made sure that the send email from address is the same as the website domain
-Checked if wordpress sends an email if I request to reset the password (it does)
-Checked if my contact form on the website still works (it does)
-Checked if the email goes to spam (it doesn’t)
-Placed test orders with different email addresses (none of them receive any order confirmation or order notes even though “WP Mail Logging” shows that the emails have been sent out).

I’m at a loss. Where do I go from here?

I’ve updated all updates needed in wordpress / plug-ins. I could not figure out what’s wrong.

P.S: I’m not really good in coding. Hoping someone can explain it to me in detail on what to do if there is a coding involved.

Kindly help me how to fix this.

Thank you so much
