SMTP Error: Could not authenticate.

    The server I believe is the issue and I think it’s Microsoft but not sure if I’m correct. Would that be how to resolve?

    All plugins are up-to-date.

    Thanks,

    Hi @catriona35,

    Thanks for reaching out! According to the error message, it appears that you have configured the WP Mail SMTP -> Settings incorrectly.

    If you’re configuring a Microsoft 365 email account, you need to generate an app password by following this guide and then update your SMTP Password under the WP Mail SMTP settings page.

    Also, make sure to update the “from email address” with your Microsoft 365 email address.

    Once you correct the SMTP settings, try sending a test email (WP Mail SMTP -> Tools).

    I hope this helps. Thanks!
