Review for Edit Email Subject (EES) by Mark B
Rated 1 out of 5 stars
Does Not Work for me at all.
Thunderbird 115.12.2 (SuperNova up-to-date) on Windows 11 Pro.
Account is IMAP.
I tried with "Back up email into local folder..." checked and not checked.
I get a "busy" icon, followed briefly by a big red Circle with a white "X" in it, then nothing.
