Thunderbird 78.0 Release Imminent
MZLA Technologies Corporation has uploaded Thunderbird 78.0 to the distribution server; this means that the new major version of the email client will be released soon.
Update: The release notes are up now. The new version of Thunderbird is offered as a direct download only, and not as an upgrade from within the client itself. The team notes that users of Enigmail should not update, that only MailExtensions will work, and that OpenPGP functionality is disabled by default.
Thunderbird 78.0 is a major release which will replace the current stable branch, Thunderbird 68.x, in the future. The release notes are not up yet, but the beta release notes provide a good overview of the major changes in that release.
Attention: Thunderbird 78 makes major changes to the extension system similarly to the changes that Mozilla implemented some time ago in the Firefox web browser. Many extensions may not work anymore after the upgrade to Thunderbird 78 as classic extensions need to be updated to stay compatible. We suggest that you test a portable version of Thunderbird 78 first, e.g. by installing the add-ons that you rely on manually, to find out which extensions are compatible and which are not.

Closing Words
It is too early for a final verdict; the final release notes are not out and there is a chance that other things have changed, were fixed, or introduced in the new version.
Users who rely on certain add-ons may want to wait with the upgrade.
Now You: Do you use Thunderbird? Will you upgrade right away to the new version?
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.

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.
