I have an alias address that I need to link to an existing mailbox. Until today, this alias was functioning solely as a forwarding address. We now need the address to function as both an incoming and outgoing address.
I was able to successfully delete the address under the forwarding tab, so it is now non-functional as an incoming address. When I attempt to register this address with the existing mailbox in my acccount, I get the following error message:
Likely a few systems Comcast must update/clean out once that was deleted. I doubt it will take 72 hours, but it could definitely take a few. The extra time is really just to cover them in-case something does get held up.
