Thunderbird 3.0.4, Lightning 1.0b1 with View->Display Attachments Inline checked
I have a meeting invitation from Outlook but there is no option to accept it.
I've read about the "Display Attachments Inline" bug, so I've set that.
I've also read that you are supposed to enable Javascript to get this to work, but TB3 doesn't support Javascript in email attachments.
So what is the solution to integrating Outlook invitations?
For me this was the primary motivation for installing Thunderbird. Without this feature will have to consider TB2 or Evolution.
Please advise.
