Add Mail Account Fails: "Configuration cannot be verified"
Hello All, I downloaded and installed Thunderbird successfully. I linked an Outlook.com email successfully. But when I tried to add a second email account (gmx.com), it failed with a "Configuration cannot be verified" error. I retried, and got the same error. Then I tried with another email account (zoho.com), and it also failed with the same error message. Any thoughts would be greatly appreciated! Thanks! -John
