Add an option box for channel e-mail creation and properties
When you create a teams channel, an e-mail is automatically created for it.
But for some channels there may not be the need to have an e-mail address and for some other channels, there may be the need to change the e-mail properties.
Currently (Apr. 2019) if you want to remove an e-mail address for a channel or if you want to modify the e-mail properties for a channel, you can do it only after the creation of the channel.
A useful feature should be to add an option box during the channel creation to choose either to create or not an e-mail address for the channel and, in case of selection, to set its properties directly.
