Secondary User account e-mail no longer accessible.

Does using Outlook to manage my e-mail not trigger sign-in to keep from deactivation? If so, that may need to be posted some where clearly so those of us who wish to keep using our e-mails know to do so manually through the website.

You will want to use the Xfinity Website to access your email. We have the specific details outlining these here:

Primary and secondary accounts
Just like your primary email account, your additional email accounts must also be accessed using the Xfinity Email website in the 90 days prior to your disconnecting service to continue to use your Xfinity Email account.

If each account was accessed using the Xfinity Email website, you can continue using each of your Xfinity Email addresses as usual.

You can use Outlook, but try to go to the website on a regular basis, as Outlook does not trigger the sign-in.

Also, there has recently been spam/phishing email that looks like it is coming from Comcast but it isn't.  When you're on the website if that email doesn't have the verified Xfinity logo next to it, you'll know that it isn't legitimate so to report it as spam.
