Thunderbird 17 released, find out what's new

Thunderbird 17.0 is the last release of the email client before Mozilla's de-prioritization of the client takes effect. What this means is that Mozilla is assigning engineers that maintained various Thunderbird related positions, like feature development, code review or marketing and engagement, to other projects. The gaps are filled by contributors which worked side by side with Mozilla in some areas.
Thunderbird 17 will be an ESR, an extended support release, which means that coming versions will be released as 17.0.1, 17.0.2 and so on and not Thunderbird 18, 19 or 20. The next big version update will then be released at the end of 2013 when Thunderbird's version will be moved to 24 to fall in line with the Firefox browser.
The release notes list the following features and changes:
- A Menu Button is now shown to new users by default
- Tabs are now drawn in the title bar on Windows
- An issue causing spell-checking only parts of words in Thunderbird 16 is now fixed (790475)
- An issue causing Thunderbird 16 to repeatedly download emails is now fixed (806760)
- RSS feeds can now be viewed in the Wide View Layout (531397)
- Various fixes and performance improvements
- Various security fixes
- Mac OS X 10.5 is no longer supported
Definitely not the big bang that Thunderbird users may have hoped the last release would be. New users see the single menu button that is already known from Firefox, while Thunderbird will display the menu bar for old users by default. Tabs are now also shown in the title bar which saves some space in Thunderbird.
Several minor changes have not been listed in the release notes. The Message Filters dialog comes with a search now which makes it easier to find filters in the manager especially if lots of filters are configured.
Another change is the option to automatically display the attachment pane when you open emails in Thunderbird that contain attachments. A right-click on the attachment pane and the selection of Initially show attachment pane enables and disables the feature in the client.
A right-click on a mailbox and the selection of properties displays information about the number of messages and the site of the messages on the hard drive.
Mozilla has improved support for Google Mail addresses by implementing support for Google's XLIST, X-GM-MSGID, X-GM-THRID and X-GM-LABELS. You may also notice improvements when copying, moving or deleting messages in the client.
Existing Thunderbird users should get automatic update notifications when they start the client for the next time (if they have not already). New users can download the latest version of the email client for all supported operating systems and languages from Mozilla. (via Sören)

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. :)
Thank you so much, this started happening to me today and was causing big problems. You are a life saver, I hope I can help you in some way some day.
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.

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.
