Cannot send outgoing email from Thunderbird desktop for Windows
Using Thunderbird desktop for Windows with my Hotmail account, I frequently cannot send an outgoing email. I regularly get the following message even while successfully receiving incoming messages.
Send Message Error Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Cannot connect to SMTP server 2603:1036:308:2817::2 (2603:1036:308:2817::2:587), connect error 10060.
I use Thunderbird for Android with the same email account without any issues. Any thoughts?

Until you post a screenshot of your SMTP server settings pane, you may not receive any suggestions.
Let me know if more info is required. This problem of not being able to send emails happens intermittently.

The SMTP looks good. That indicates (to me, but I'm no network guru) that the error message is correct - that there are intermittent network problems.
However, when the message fails to send from Thunderbird for Windows, I have tried my phone with Thunderbird for Android using the same email account and I even disabled my cellular data so that my phone was the same wifi as my computer. The message goes thru from my phone just fine. I immediately went back to my desktop and it still won't send. So it seems like the issue resides in the Windows app.
I did some checking on others having the 10060 error and theirs were resolved by adjusting firewall/anti-virus settings.
