Support » Plugin: WP Mail SMTP by WPForms » Test email not sending to Outlook

  • Resolved amykitupforta



    I am trying to send a test email to my Outlook email via WP Mail SMTP, but having followed the suggested documentation, Googling all my problems and asked my hosting provider (Crazy Domains), it’s non-functioning.

    The steps I took:
    1/ Installed WP Forms, created a simple 3-field form with no edits done to it. Put shortcode into Elementor web builder.

    2/ Installed WP Mail SMTP, selected settings for Outlook:
    From email: (my outlook email), forced from email
    From name: (named it), forced from name
    Other SMTP
    SMTP host:
    Encryption: TLS
    SMTP Port: 587
    Autentication: ON
    SMTP username: (my outlook email)
    Password: (password to login to my outlook email)
    Saved settings

    3/ Attempted to send test email. “Waiting for” for a while, then 504 Gateway Timeout.

    4/ Contacted Crazy Domains. Suggested I turn off encryption while using Port 587. Did so, as well as using Port 25 and trying every combination with encryption & auto TLS. Same error.

    5/ Saw PHP sticky post update. Tried PHP…got an instant “your test email has been sent” but no mail delivered. My WordPress is hosted by Crazy Domains and they do recent updates, most recently today. I should have PHP 7.2…

    6/ I have another website on the same hosting service account, which also use WP Forms & WP Mail SMTP and has connected to a Gmail account following your documentation.

    Any other clues guys? First time building a website, so I don’t speak the backend lingo at all, please be kind – I’d love a few pointers to anything I missed. Thanks!

    Hi Amy,

    The 504 Timeout error occurs most likely if incorrect SMTP settings used. You will need to contact your hosting provider once again and request correct SMTP credentials. Some hosting companies (like Bluehost) provide own host/port/username/password/encryption/authentication.

    Hi Amy – We haven’t heard from you in about a week, so I’m going to go ahead and mark this ticket resolved. If you still have questions, though, please feel welcome to continue the conversation.

    Hi Sanjeev,
    I’ve contacted my hosting provider (Crazy Domains) and Outlook, and they both said there’s nothing wrong on their end. Basically everyone is blaming the other party, so I’ve given up the contact form since I can’t find answers and I have no html skills to look further into it.Thanks.

    Hi Amy,

    I really apologize for the trouble here — I definitely understand that this situation is super frustrating. Unfortunately, the current issue you’re running into is almost definitely hosting related.

    But the good news is that I have a suggestion that will very likely get around all of this: setting up a different mailer within WP Mail SMTP. The “Other SMTP” mailer that you’re using right now will often run into server related issues, however all of the other mailer options in WP Mail SMTP have a different fundamental design that helps them to avoid most of these kinds of issues (they use APIs rather than traditional SMTP).

    Specifically, I’d recommend checking out our Mailgun or SendGrid mailers.

    These are both super reliable mailer options, and have free account plans that tend to work just fine for many small business owners. If you click either of those links, you can check out all of the setup details for either option.

    I hope this helps! 🙂
