Unable to set up Thunderbird Mobile on my Android phone

I should also add, when I try to put in the settings (which I know are correct, same as what I have in Thunderbird Desktop), it comes up with "Checking incoming server settings failed Network error Details: Unable to resolve host "twc.mail.com": No address associated with hostname. I positively know that is correct.

This is the Thunderbird for desktop operating systems forum. You might be better off asking your question in the Thunderbird for Android forum where its experts reside.

But I will say this... Spectrum (including, presumably, TWC) has been having severe connectivity problems that affect all email agents, for several weeks at least, though they rarely admit it. We are watching the situation closely, but there's not much we can do.

According to Spectrum's help web page <https://www.spectrum.net/support/internet/mobile-email-setup>, that is a valid address, but it is not online right now, which is why you're getting the "Unable to resolve host" error. Hopefully that's a temporary situation, but you would have to check with them for status.

Moving this topic to the TBfA queue.

This is a duplicate of https://support.mozilla.org/en-US/questions/1604884 I've responded to that post.

The correct server name is mail.twc.com, not twc.mail.com
