Lightning: event replies are marked "TENTATIVE" instead of "ACCEPTED"

[Régis Desgroppes]

Binary package hint: thunderbird

1)
Ubuntu 9.04

2)
thunderbird 2.0.0.22+build1+nobinonly-0ubuntu0.9.04.1
lightning-extension 0.9+nobinonly-0ubuntu2

3)
When accepting an invitation, the generated .ics file contains X-MICROSOFT-CDO-BUSYSTATUS:TENTATIVE
The event is marked "tentatively accepted" in Exchange.

4)
It should be something like X-MICROSOFT-CDO-BUSYSTATUS:ACCEPTED
The event should be marked "accepted" in Exchange.

Thank you very much,
Regis

Can you please post the output of the following commands as typed:
apt-cache policy lightning-extension thunderbird
ls_release -a

Also as i recall this has been reported already. Can you please see if it works in sunbird from repos?
Also please file this upstream with mozilla and add the link to this bug report so we can track it.
