I have been using Thunderbird for emails for a couple of years now, without problems. In the last couple of weeks there has been a marked increase in the number of empty emails being received by customers, I write the email and they receive contentless emails.
It generally happens when using the reply button rather than just writing and sending a new email.
To the vastly more knowledgeable on these things than me, is it an problem at my end or Mozilla's?
Is there a fix? Or should I simply change, kicking and screaming, to Outlook?
