Answer 1

To assist you better on this issue, could you please provide the following info:
Since you have posted the question on Azure App Service?
Is your WordPress webapp hosted on Azure WebApp or on Azure VM or some other Azure service?
Are you referring to any Azure doc for the steps/process?
Does it work fine locally? You would typically setup and config WordPress site, as you would on-prem.

Typically, just to highlight, the error message you’re seeing suggests that the email address format for the client is invalid. This could be due to special characters in the “From” name or “From” address fields in your WooCommerce email settings.

 

You may want to know, the WordPress on App Service can integrated with Azure Email Communication service to enable email feature. You take a look at the approach outlined in this article WordPress on Azure AppService - Email Integration.

On App Service: The wp-config.php files can be updated using either Kudu console or FTP Client (such as FileZilla).

1. Browse to Kudu : http://”yoursitename”.scm.azurewebsites.net. Example: if your Azure App Service Web App name is “testwebapp”, then surf to http://testwebapp.scm.azurewebsite.net
2. Click ‘Debug Console’ and select ‘CMD’ Traverse to wwwroot folder
3. For WordPress, update wp-config.php -make necessary changes, and save.
