When clicking on name in address book -the email address appears different in the email address bar and can't be sent -why?

Question

I have been using thunderbird for some years - in last month when I have been trying to send some emails I have a problem with some of them in that part of the email address has changed when I insert it ino the address bar and has inverted commas around the first part of the address before the @. I have tried deleting the addresses and re-inserting them but the same thing happens. If I go into the address bar and delete the commas the email is sent - can I overcome this problem without having to go into each email? I send out emails to many people and changing each one that has the problem takes a long time. Not every email address has this problem. Many thanks -Tim

Answer 1

ok, I've spent some time doing various scenarios.
I have managed to replicate one scenario which does as you say.
If my contact in the address book:
With name details as Peter Foo
email address: [email protected]
where there is an inserted space before the name peter, of course this is not instantly noticeable, but it is as if you hit the space bar just before typing the email address.
Then when I use the Contacts Sidebar in a Write message, it will add the email address like this:
Peter Foo <" peter"@somewhere.com>
which of course in invalid.
but in the address book, if highlight the contact, in the section below the email address in blue -if I click this to send an email the email address is printed exacly with the space and it will send as if nothing is wrong.
So i'm asking you to check those email addresses which insert incorrectly via the Contacts sidebar. They only do this for me if there is a hidden inserted space at the start of the email address.
