the email attachment underscore is a security feature, it is intended behavior
you seem to just be a disgruntled user with unrealistic expectations of fix-it-now and perfection, you will find unacceptable fault eventually no matter what you install
Eh? It was a major issue and was renaming all attachments upon landing in outlook. It wasn't intended and the fix then was to disable attachment renaming altogether. Claimed they couldn't undo the issue then under pressure from customers, finally released a convoluted fix.
See here
Its an accumulation of issues over the space of a year.
I'm not demanding a fix it this minute approach. My point was, the issue was reported, the issue has been replicated, they know what's causing it, they know what the fix is, but can't push the update for another 2-4 weeks?
If you take a look at the official thread on their forum, you'll see that this has impacted customers businesses (people ringing or emailing asking why their website is down - it's not, it's done to the AV), COVID related websites etc.
It's a pretty big issue.
I'm fine with finding fault. We're human after all, it's how the faults and mistakes are handled that matters.
thanks for your feedback
