Hi @Richard Duane Wolford Jr ,
Welcome to our forum!
Does anyone know if there is a way to set Outlook Web Access as the default mail application using Group Policy?
Based on my research, i found that Outlook Web Access can not be set as default, as it is not an application. We can only choose one of the several optional apps listed to set it as the default client.
But for the use of GPOs to set the default mail client you mentioned, please refer to this:
configure the default email client using Group Policy
Hope to help you!
