Thunderbird 78.2.2 email client update is out

The Thunderbird email client team has released a new version of the program for all supported operating systems. Thunderbird 78.2.2 is a bug fix update for the most part but it introduces a new feature and changes as well.
The update is already available via the email client's automatic updating system. Thunderbird users may select Help > About Thunderbird to start a manual update query. The client will pick up the update then and install it on the system.
The new version is also available on the official Thunderbird project website. Just download it and run the installer to update the existing installation to the new version.
Note: Versions prior to 78.x won't be updated to the new version via automatic updates. A manual update is required to update. Thunderbird 78 introduced many changes to the email client, including support for MailExtensions. Classic extensions cannot be used anymore.
The first change becomes apparent right after the first start; Thunderbird opens the privacy policy in a new tab in the email client when it has been updated. The last update of the policy, at the time of writing, is August 30, 2020.
Thunderbird 78 introduced recipient pills functionality, similarly to how Gmail and other email services display recipients. The updated version supports drag and drop operations; you can drag and drop recipients to other recipient fields, e.g. from CC to BCC using the new functionality.
Twitter chat support has been removed completely in the new version. As far as fixes are concerned, many patch issues in the built-in OpenPGP functionality that has been enabled in the previous release version.
The "discover key online" feature is now working when you search using an email address, and decryption should work now as issues with certain "HTTP proxy configurations" has been addressed.
Other fixes in the new version include improvements to Windows 10 high-contrast theme setups, making event reminder details readable in the Calendar, and fixing an issue that caused the sending of messages to fail when recipients were in LDAP address books.

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. :)

You are a god – thank you!

Yah…thanks Claude. I’ve been having the same problem and tried all the suggestions…your solution was the answer. It had resized itself to a 0/0 box. Cheers

Thanks a lot. I was facing this issue from past 3 week. I tried everything but no resolution. The issue was happening intermittently and mainly when I was changing the display of screen ( as i use 2 monitors). The only option i had was to do system restore. But thanks to you.
I’ve been tried to sole this problem for 12hours. Your comment about changing the display of screen helped me a lot!! Thanks!!

This problem was faced by only one user logging to TS 2008 r2 using outlook 2010.The issue was resolved.
Thanks.
Great tip. Thank you!!!! If it helps, I had to use the Control Key and the arrow keys at the same time to bring my window back into view. Worked like a charm.
Thank you, this worked !!!!
