The Get email Address option is not available channel option list.
you have to check in Teams Admin Center -> Org-wide Settings -> Teams Settings -> Email Integration if you have "Allow users to send email to a channel email address" enabled.
Also, to get Channel email address you have to be a Team Owner.
Agree with Luca, you need to turn on “Allow users to send email to a channel email address” in Microsoft Teams Admin Center.
It needs to wait up to sometime for this setting to take effect.
As I know, except the team owner, the channel member can also get the channel address. For more details, please refer to this article:
This is not an answer but something I have noticed. 6 days ago, I created two teams with an additional channel per team. The email address for the general channel was ready, but the email address for both channels was not, and I was stuck on the "We're still setting up your team. Please try again later." message. Just now, when I wanted to check the channels again, it was ready to use and the email address was ready as well. In the admin portal, the envelope icon wasn't showing, but now it is. 24 hrs to setup the channel is understandable, not almost a week. This behavior is seriously weird, especially that there are no time indicators. Is this a bug or something?
I'm going on 7 days at this point with it still staying "We're still setting up your team. Please try again later"
