[Branda Pro] Add support for Microsoft 365 Mail

0

Branda supports SMTP connections but it doesn’t support Microsoft 365 because Microsoft has changed their requirements. Now you have to user their APIs in order to create app IDs, client IDs etc in order to connect Outlook to a site.

FluentSMTP has a step-by-step guide on how to do this (https://fluentsmtp.com/docs/setup-outlook-with-fluentsmtp/#add-new-microsoft-connection).

Unfortunately I had to disable Branda and install FluentSMTP to make Outlook work on a client’s site. I’ve also wasted ~20 minutes of a support agent’s time because there is no documentation for this case and he didn’t know why Branda doesn’t work, even though SMTP and the credentials were correct.

    Ok, so I have been using Fluent SMTP and it kinda works…. as in after playing around with the user levels to get an account that has Entra credentials and can set up the app ID and other credentials and setting teh authorisation longevity for 2 years – the plugin works ……… for bit! Have had this exchange with their support:

    =======
    But after a month I get:

    FluentSMTP Plugin may not work properly. Looks like your Authentication unique keys and salts are changed. Reconfigure SMTP Settings

    Which I can do, but after this has happened for a few months, I am getting fed up of emails not sending, having to reconfigure and then resend all the failed emails. It is happening on more than one site and it is becoming problematic – to the point of not being useable with MS 365

    Any idea why this is happening and is it the MS credentials changing of those of WordPress? I have WPMU Dev Defender Pro installed.

    Their reply:

    Thanks for reaching out to WPManageNinja support.
    Based on the information you’ve provided, it seems like the issue might be related to a security plugin modifying the unique SALTS in your WordPress wp-config.php file. Some security plugins, including WPMU Dev Defender Pro, can automatically update these keys and salts for added security, which could cause the authentication credentials to reset every time this happens.
    To resolve this, I recommend checking the settings of your security plugin to see if it has an option to automatically regenerate the WordPress keys and salts. If that’s the case, you can either adjust the settings to exclude wp-config.php from these updates or disable the automatic regeneration of keys and salts altogether.
    Additionally, you may want to confirm that the Microsoft 365 credentials remain unchanged during this process and that no other security features are interfering with the authentication process.
    This should help ensure that the FluentSMTP connection remains stable and prevent the need to reconfigure it repeatedly.

    SO my questions are:

    1. Is their answer realistic?
    2. How do I find the setting for this in Defender Pro (can’t see it in the documentation)? and,
    3. What is the downside of turning such a setting off?

    Hi TrueHammer ,

    I hope you are doing well today!

    The answer provided by WPManageNinja support seems realistic and plausible. Security plugins like Defender Pro can modify the unique SALTS in the wp-config.php file, which could potentially cause authentication issues with plugins like FluentSMTP.

    To find the setting in Defender Pro that controls the automatic regeneration of WordPress keys and salts, you can navigate through Defender Pro->Recommendations->Update Old Security Keys

    The downside of turning off the automatic regeneration of keys and salts in Defender Pro would be a potential decrease in security for your WordPress site. These keys and salts play a crucial role in encrypting sensitive information and securing user data. Therefore, disabling this feature could leave your site vulnerable to security threats. It is important to weigh the convenience of not having to reconfigure plugins like FluentSMTP against the potential security risks of disabling this feature.

    Kind regards,

    Hi again TrueHammer

    11 months on, any news on BRANDA working with MS 365? Surely there should at least be a 1/4 target for the solution?

    I understand your frustration, and apologize for not being able to provide you with a specific timeframe for a fix. However, please rest assured that our Branda team strives to fix each bug and feature request/improvement as quickly as possible.

    In general, providing an ETA for can be challenging since our developers need to consider the issue’s complexity, prioritize tasks depending on their severity, and manage their workload. Those fixes should also be checked by our QA team. This is why we could not provide a clear timeline for the specific issue you’re experiencing.

    Thanks for your understanding.

    Kind regards,
    Zafer
