Thunderbird Mute Thread, Ignore Email Conversations

When it comes to email conversations with multiple participants, it sometimes happens that the discussion takes a turn that is no longer of interest to individual users.
This can be a discussion on a mailing list for instance, where other members of the list discuss specific topics.
Being part of the mailing list however means that those emails arrive in every user's inbox. It also means that all users have to deal with the messages, which often means marking them read or deleting them entirely.
Mute Thread is a new experimental add-on for the Thunderbird email client that gives the user the ability to mute individual email threads. In theory, this means that muted threads do not appear anymore in the email client's inbox.
The emails are not deleted, just hidden from view, and Thunderbird users can display them again by clicking on View > Threads > Ignored Threads in Thunderbird. It is necessary to switch to another mail folder temporarily to display the hidden messages again in the active folder.
Threads in Thunderbird can be muted by clicking on Message > Ignore Thread or using the shortcut K for the same effect.
Mute Thread in its current stage is what the developers call an experimental add-on. This means that the devs have plans to integrate it into the email client eventually, but do not have an idea how and when this is going to happen.
Currently the devs are looking for one or two developers who would like to take over the project. The Mozilla Labs post offers additional details about Mute Thread and contact information for developers who would like to participate in the development of the add-on.
The add-on is available for download at the official Mozilla add-ons website. It is compatible with Thunderbird 3.1 to 3.3a only.
Update: Mute Thread functionality has been integrated into the Thunderbird client. You can right-click on any message in the program now to ignore the thread or sub-thread.
It is no longer necessary to install the add-on for the functionality.

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. :)

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 !!!!
