.SYNOPSIS
Rename-Team changes the email address of a Team. This is done because when Users Rename their Teams and they expect the email will be changed as well.
This cmdlet was designed for users. Current group name and new email address will need to be entered by the user after the cmdlet is run.
The user may need to be granted permissions to change this setting and also be the groups owner. Or you can just do it for them.
.DESCRIPTION
Renaming a Team in Office365 does not automatically change the email address.
This cmdlet is used to allow users to rename their Office365/Team email.
