(background) -------------------- I'm still running Windows 7 (it works for me) and Thunderbird (version 115.16.2 (32-bit)) has been my e-mail client application for many years. Inside Thunderbird I have a series of sub-folders (which I shall refer to as 'folders') named & arranged by years & months. Any received e-mails that are 'personal' (i.e. not news items, previously OK'd advertising, or junk) get filed into the current month's folder (which is 'inside' the current year's folder). (Towards the end of a current month I create the next month's folder.) I used a wired USB mouse with two buttons ('left' & 'right'). When things are working like they are supposed to (and I have received a piece of personal e-mail that I want to store) I 'left click' on the e-mail (in the 'inbox') and (while holding the 'left button') 'move' the e-mail into the current month's folder. -------------------- (the 'problem') Once in awhile I accidentally click the 'right button' during the process of moving an e-mail from the 'inbox' to the current month's folder. To-all-appearances the e-mail 'disappears' though a few times I have found it in an 'adjacent' month's folder (I also look in the 'trash' folder'). So far my only 'solution' (I at least have a copy of the message) is to go to my e-mail server (I have it configured so that it does not automatically delete messages) and 'forward' the message to myself (in which case I am shown as being the 'sender' when the message arrives in the Thunderbird 'inbox'). ----------------------- (my question) Does Thunderbird have an (undocumented ?) 'disintegrate' action ... where a message can be completely erased as a result of an accidental right mouse button click ... or is there some other folder where I should look (other than 'adjacent' month's folders and the 'trash' folder) ?
