    FluentSMTP uses OAuth with Microsoft to generate a token based on the Application (client) ID, client secret, and the specific Microsoft account being authorized. Since the same app works with another account, the issue is specific to the primary account configuration/permissions, not FluentSMTP itself.

    From the provided context, the only supported guidance related to WordPress and Azure is how to integrate email via Azure Communication Services rather than via individual mailbox OAuth tokens. For WordPress running on Azure App Service, email is expected to be sent using Azure Communication Services instead of directly authenticating a mailbox with plugins like FluentSMTP.

    To avoid the token issue for that specific account, configure WordPress email to use Azure Communication Services as the SMTP/email backend for the site, and then send mail from WordPress through that service rather than directly through the problematic mailbox.
