Title: Incorrect authentication data Last modified: August 30, 2016 --- # Incorrect authentication data * Resolved [DestinyFacts](https://wordpress.org/support/users/destinyfacts/) * (@destinyfacts) * [10 years, 6 months ago](https://wordpress.org/support/topic/incorrect-authentication-data-3/) * I am trying to get my contact form 7 to work on my website but everytime I submit I get “Failed to send your message. Please try later or contact administrator by other way.” * I downloaded the Postman SMTP Mailer plugin but I get a “Incorrect authentication data” when I try the test email. * This is my Office 365 email settings: **SMTP setting** Server name: smtp.office365. com Port: 587 Encryption method: TLS * Here are the settings I used in the plugin below, please help. * **Outgoing Mail Server Hostname** relay-hosting.secureserver.net * **Socket** SMTP – secureserver.net:587 * **Email Address** [TonyL@Littleshots.org](https://wordpress.org/support/topic/incorrect-authentication-data-3/TonyL@Littleshots.org?output_format=md) * Sending the message: Failed Incorrect authentication data * **How will you prove your identity to the mail server?** * When it asks for username & password (ABOVE) what do I need to put in? Is this my issue? My Contact form 7 from is: [your-name] <[your-email]>, does this need to be changed since it states “The Username is usually the same as the Envelope- From Email Address.” * **Troubleshoot** OS: Linux a2plcpnl0124.prod.iad2.secureserver.net 2.6.32-531.29.2. lve1.3.11.10.el6.x86_64 #1 SMP Fri Jun 12 15:09:02 EDT 2015 x86_64 PHP: Linux 5.4.43 C PHP Dependencies: iconv=Yes, spl_autoload=Yes, openssl=Yes, sockets= Yes, allow_url_fopen=Yes, mcrypt=Yes, zlib_encode=Yes WordPress: 4.3.1 en_US UTF-8 WordPress Theme: theme51348 WordPress Plugins: All-in-One WP Migration, Cherry Lazy Load Boxes Plugin, Cherry Plugin, Contact Form 7, MotoPress Content Editor Lite, Postman SMTP, Go Daddy Quick Setup, Seamless Donations, Search Engine Visibility, WordPress Importer WordPress wp_mail Filter(s): wp_staticize_emoji_for_email Postman: 1.7.2 Postman Sender Domain (Envelope|Message): LittleShots.org | LittleShots. org Postman Prevent Message Sender Override (Email|Name): No | No Postman Active Transport: SMTP (smtp:tls:plain://relay-hosting.secureserver.net:587) Postman Active Transport Status (Ready|Connected): Yes | Yes Postman Deliveries (Success |Fail): 0 | 14 * [https://wordpress.org/plugins/postman-smtp/](https://wordpress.org/plugins/postman-smtp/) Viewing 6 replies - 1 through 6 (of 6 total) * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [10 years, 6 months ago](https://wordpress.org/support/topic/incorrect-authentication-data-3/#post-6767225) * The reason for the error is you are connecting to secure server.net instead of smtp.office365.com. The two different servers have two different accounts for you, with different passwords for each. The wizard should have warned you about this during setup. * **The more general answer is that you can’t directly access the Office365 server throug GoDaddy because they block the ports. ** * If you have access to cPanel at GoDaddy, you can try enabling the Remote Mail Exchanger. I’ve heard that works for some people with Office 365. * Otherwise your only options at godaddy are: - Godaddy email - Gmail with the Gmail API - Any email with the Mandrill API - Any email with the SendGrid API * I recommend signing up your office 365 email at SendGrid. That’s what i would do in your situation. * I hope that helps you! * Cheers, Jason * Thread Starter [DestinyFacts](https://wordpress.org/support/users/destinyfacts/) * (@destinyfacts) * [10 years, 6 months ago](https://wordpress.org/support/topic/incorrect-authentication-data-3/#post-6767237) * On the Postman SMTP Setup Wizard Setup * How will the connection to the mail server be established? Your connection settings depend on what your email service provider offers, and what your WordPress host allows. * Postman recommends 🔐SMTP-STARTTLS with Password (Plain) authentication to host smtp.office365.com on port 587. * Socket: * 🔒 SMTP – office365.com:587 🔒 SMTP – office365.com:465 🔒 SMTP – office365. com:25 🔒 Mandrill API 🔒 SendGrid API Authentication: * Password (requires username and password) **Warning: connected to secureserver. net instead of office365.com.** * I enter in smtp.office365.com but it gives me this warning.

You are actually connecting to secureserver.net, not smtp.office365.com. **GoDaddy prevents direct connections to Office365. ** * As I mentioned earlier: Try setting enabling the Remote Mail Exchanger in cPanel. * If that doesn’t work, use a different service like SendGrid. * Thread Starter [DestinyFacts](https://wordpress.org/support/users/destinyfacts/) * (@destinyfacts) * [10 years, 6 months ago](https://wordpress.org/support/topic/incorrect-authentication-data-3/#post-6767258) * I tried enabling remote mail exchanger, did not work. * I found this in the cpanel: **Manual Settings** If you do not see an auto-configuration script for your client in the list above, you can manually configure your mail client using the settings below: * Secure SSL/TLS Settings (Recommended) Username: [tonyl@littleshots.org](https://wordpress.org/support/topic/incorrect-authentication-data-3/tonyl@littleshots.org?output_format=md) Password: Use the email account’s password.

Outgoing Mail server hostname but it still gave me Incorrect authentication data. * Is there anything I can do with this information? I feel like I am putting in something wrong for the wizard, or I am missing/accidently deleted the MX record the plugin needed. * I dont understand what you mean by using a different service. Does that mean canceling my 365 office account and installing another plugin? Geez ive been trouble shooting this contact form for days now.. is there a faster way to msg someone who can help me? * Thread Starter [DestinyFacts](https://wordpress.org/support/users/destinyfacts/) * (@destinyfacts) * [10 years, 6 months ago](https://wordpress.org/support/topic/incorrect-authentication-data-3/#post-6767261) * My donations plugin is not sending emails either. I used Seamless-donations. Do you know what MX record I need to have to make that work? * Thread Starter [DestinyFacts](https://wordpress.org/support/users/destinyfacts/) * (@destinyfacts) * [10 years, 6 months ago](https://wordpress.org/support/topic/incorrect-authentication-data-3/#post-6767272) * I think the problem was that my MX record has both my godaddy local c panel email and another record for my office 365 remote email. * I am removing my local one, and changing that setting again to remote mail exchanger. * Will update late tomorrow with progress, thanks.
