I have a bunch of users who use an application and when that application does an update it automatically sends an email on behalf of whoever is doing the task... My issue is when someone says no and un-checks to make it so the message never pops up again , it stops it for working on that user. At first I tried to add mapi.blind-send.warn to true and it does not pop up... If I totally uninstall thunderbird and delete the profiles in %APPDATA% I still end up with the same issue... my only solution thus far is I have to create a new windows user to get it to totally reset to make it work. I am wondering how to reset thunderbird so I don't have to do this...
