Hi @EnzoSalernoCompleteMachineTools-1331
Welcome to our forum!
Outlook does not support the unified management of templates for all users in an organization. Message templates can only be controlled and managed by individuals themselves.
If you want all users to use the prescribed template when sending emails, we recommend that you format the template for all users and ask them to follow the template requirements when sending emails.
Also, to get this feature more quickly, I have found a post in feedback collection website, and you could vote for it. Many features of our current products are designed and upgraded based on customers’ feedback. You can also make suggestions on that website and hope Microsoft will notice this in the future. Thank you for your understanding and support.
