Is it possible to speak with a live support agent?

@user_78cbt9 

I’m receiving the message stating my email mailbox is full. I’ve permanently deleted hundreds of emails. 

Have you deleted those emails from Trash?

Also, delete your cache and cookies for xfinity.com, close out of email; close out of Xfinity; close your browser and then start a new session.

Hey there, user_78cbt9! Thank you so much for taking the time to reach out to us on the Xfinity Forums! Thank you @Again for sharing those troubleshooting steps. Have you had a chance to attempt them? How are you accessing you email? Are you using a 3rd party mail client?
