From Name does not work in any case (office365)

Hi, I’m using WP Mail SMTP, and a contact form using Contact Form 7.

In my form settings, in the “mail” tab, for “From”
I have myname<[email protected]>

But all emails from this form arrive with a FROM name of “web”

In the “WP Mail SMTP” plugin, I’ve set the FROM name as “myname”, and have checked the “Force From Name” box.

We are using smtp.office365.com for our SMTP, if that makes a difference.

I really don’t know what else to try. Any advice?

Thanks!
