Hi there,

I've just recently started to get error messages using Thunderbird. I've made no changes and it seems to be intermittent.

Error message;

An error occurred while sending mail: Unable to establish a secure link with Outgoing server (SMTP) smtp-mail.outlook.com using STARTTLS since it doesn't advertise that feature. Switch off STARTTLS for that server or contact your service provider.'

Receiving email seems to be OK.

Any advice welcomed!

Dave
