OR Microsoft adds support for custom addresses e-mail in its services Office 365, a possibility that hopes to be completed in the third quarter of 2020.
It is known as a secondary address. This template allows users to extend their email address using the "tags" or plus (+) character.
The "tag" can be unique each time, allowing users to create an infinite number of custom email addresses, which they can add to shopping companies, newsletter subscription forms, contact forms and other online forms.
Note that this function already exists in gmail of Google.
