Invalid Email Error
All of a sudden my iphone is not getting new emails for my sbcglobal.net email address. It also is not able to show the messages of older ones there just before this happened. ( I still get new emails on my home ACER computer.) I went into Settings, Name, Phone number, Emails and the sbcglobal.net email address is there and correct. I selected EDIT and deleted it and thought I could add it again, but it is not accepting it. I select add email address and put in the same email address and it says Invalid Email.....this email address is not available. Choose a different address.". This is the one I need to add.
iPhone 11 Pro, iOS 15
