Need to change From name displayed in Wordpress

Question

I'll do my best to describe this issue. It begins in Wordpress but it must be caused by some configuration with Microsoft 365.

On my website, I use the plugin WP Mail SMTP. The problem is that the From Name is set to my old organisation name. It's greyed out so I cannot manually change it. Here's a screenshot of what I'm seeing:

As part of the configuration of the plugin, I set up an app registration on my Azure tenant according to their instructions here. Also, I used to have a business plan with Microsoft 365 but quickly reverted to a personal plan. Could some of the configuration I made there be 'stuck' to my old organisation name?

I'd ultimately like to know how to remove any trace of my old organisation from my Azure account.

N.B. I posted this question answers.microsoft.com originally but the moderator told me to post here instead.

Hi, @helpmeplenty

I have checked and answered the WP Mail SMTP documentation.
https://wpmailsmtp.com/docs/how-to-set-up-the-outlook-mailer-in-wp-mail-smtp/

I think you registered your application and set it up for WP Mail SMTP, but you may have registered your application in another tenant as you expected.
You can re-register the application.

I'm not sure, but looking at the WPMailSMTP documentation, it looks like you can remove Conneciton. So, you can reset the grayed out part by deleting and recreating the connection.
