I mapped an Org wide with specific profile still User with different Profile are able to see that org wide email while sending email form salesforce in my Salesforce Org
I encountered a similar issue in one of my dev orgs where I had correctly mapped the Org-Wide Email Address to a profile, but users from other profiles were still able to view it. The reason was that I had initially set the Org-Wide Email Address for all users and later restricted it to specific profiles.
I spent a significant amount of time trying to figure out why users from other profiles could still see it. The issue was similar to what is described here: Organization-Wide Addresses do not immediately show up in Lightning User Interface.
Please verify everything again, and if everything seems correct, give it some time. In my case, it took about an hour for the changes to take effect.
