How to change a Team email
There are a lot of reasons that can lead you to a rename of a Team, either because the self-creation is enabled, and the names don’t follow the internal rules or simply because the name no longer makes sense.
On Microsoft Teams you have a graphical interface that will allow you to change the name and the description of the Team however the email will not change to reflect the modification.
To modify the email, you will need to use the Exchange PowerShell below to create a new alias and delete the old one.
