Comment 9 for bug 615631

Sorry for re-posting straight after my own posting... I've just downloaded the 0.12 add-on from the home page (https://addons.mozilla.org/thunderbird/downloads/file/101514/provider_for_microsoft_exchange-0.12-sb+tb.xpi) Installed version says it's v0.11, file 101514 appears to be the old version.

Just for info to other reading this, the correct URL is https://addons.mozilla.org/thunderbird/downloads/file/109818/provider_for_microsoft_exchange-0.12-tb+sb.xpi?src=version-history

I've managed to install the v0.12 version and it is still exhibiting the same issue.

Set the Exchange 2010 IMAP4 service so that the meeting invites appear as iCalender, and not a URL.

1. Create Gmail event, invite internal exchange participant and others in other domains.
2. Using the iCal invite in the Exchane Inbox, accept the meeting.
3. Meeting invite is re-issued to all participants in all domains.

HOWEVER

If you use the "Invitations" link at the bottom of the Thunderbird status bar and accept it that way, then the meeting request is *not* reissued to everyone. Everything works as expected.
