Use BCC Instead For Thunderbird For Better Email Privacy

When it comes to sending emails to multiple recipients you have several options at your disposal. The most common options are to use To, CC or BCC for that.
The first two options may cause privacy issues as they reveals all email addresses to all recipients. That may not be a problem if you are sending out emails to people that work all for the same company or organization, but may very well be one if recipients do not have anything to do with each other.
One example where this could be a problem are the giveaways that I hold here on Ghacks regularly. I usually have to email ten or even more winners of licenses and it would not really make sense to let everyone see each others email addresses in those emails.
Use BCC Instead is a Mozilla Thunderbird extension. It works almost like the native attachment warnings that you get when you use words like attached in the email body or subject without attaching a file to the email.
The extension warns you whenever you send emails to multiple recipients using either To or CC instead of BCC.
Please note that the extension warns you about sending the email to multiple To or CC recipients. It gives you the option to go ahead and send it anyway, or to click cancel to modify the parameters to BCC. It does not auto-correct the issue.
The default limit is set to 10, which means that you only get warnings if you send out emails to more than ten recipients using To or CC. You can change that in the options, for instance to 1 which would always warn you when To or CC is used.
You can furthermore block emails from being send out at all if the selected value is exceeded.
You can also make additional changes to the configuration. It is for instance possible to change the default messaging form from TO when composing new emails or forwarding messages to another form, or configure the extension to always substitute BCC for TO and CC recipients.
Thunderbird users can download Use BCC Instead from the official Mozilla extension repository.

You said that Outlook isn’t your main email client, so which is your main one?
I think its thunderbird
It is Mozilla Thunderbird.
Awesome! This actually solved my problem… what a stupid bug.
If this is the same bug that I’ve encountered, there may be another fix: (1) hover over open Outlook item in Taskbar, cursor up to hover over Outlook window item, and right-click; (2) this should give you Restore / Move / Size / Minimize / Maximize — choose Move or Size; (3) use your cursor keys, going arbitrarily N/S/E/W, to try to move or size the Outlook window back into view. Basically, the app behaves as though it were open in a 0x0 window, or at a location that’s offscreen, and this will frequently work to resize and/or move the window. Don’t forget to close while resized/moved, so that Outlook remembers the size/position for next time.
THANK YOU Claude!!! I could get the main window to launch but could not get any other message window to show on the desktop. You are my hero!!!!
Solved my issue! 6 years later and this is still problem…
Fantastic. Thank you. Size did the trick.
This solved my Outlook problem, too. Thank you. :)
