--- Comment #5 from René Krell <renda.kr...@gmail.com> --- Just for the record, as a hint: Thunderbird 45.8.0 does show this kind of messages (TNEF) without any trouble - in header there appears: "This message contains an invitation to an event." with the Decline | Tentative | Accept buttons. Which probably means this seems not to be an authorization or other integration problem. -- You are receiving this mail because: You are watching all bug changes.
