Hello @adam198,
Regarding your current configuration, Microsoft accounts typically don’t natively support sending emails directly from aliases when connected through FluentSMTP. While you’ve configured the alias in Microsoft 365 and enabled sending from aliases in Mail flow settings, these settings might not fully translate to FluentSMTP’s connection.
To resolve this, the most effective approach is to contact Microsoft 365 support. They can help you enable the necessary features and permissions within your account that will allow FluentSMTP to send emails via your configured alias. You might need specific settings or permissions that are not enabled by default.
Once Microsoft has enabled the necessary features, you should be able to configure FluentSMTP to send emails from your alias address.
Let me know if you have any other questions!
We’re having the same issue. We enabled the ‘turn on sending from aliases’ option in the Microsoft 365 Admin Center but it’s still not adopting the from email address and name set in your plugin.
Does your plugn support alias-specific sending via Microsoft Graph OAuth? Does your plugin construct the Graph API call correctly with "from": {"emailAddress": {"address": "[email protected]"}} ? I believe the ‘from’ name can’t be changed at all when using Microsoft?
