Do you perhaps mean that your Comcast/Xfinity email has been migrated to Yahoo?

If so, Classic Outlook will try to connect you to the Comcast Mail Servers because your email ends with comcast.net. You have to trick Outlook into using the Yahoo Mail Servers instead. For step-by-step instructions see:

First, sign in to Xfinity Email and make sure access for third-party email programs such as Outlook is enabled. Xfinity requires this setting before Outlook can connect to your Comcast.net mailbox, as mentioned here:

Then, in classic Outlook:

1. Go to File > Add Account.
2. Enter your full Comcast/Xfinity email address, for example ******@comcast.net, and select Connect.
3. Enter your Xfinity password if prompted. Microsoft confirms that classic Outlook can add additional accounts through File > Add Account.
