Hi, I'd like to try to configure an Exchange (Office 365) account in Thunderbird Beta, and it doesn't work for me. I use the autodiscover and: 1. Thunderbird tells me that it can recover the connection settings, okay 2. It offers me IMAP, POP and Exchange/Office365. If I select the last one, it says that the server doesn't allow open protocols and that I must install/pay the Owl extension. 3. If I select "configure manually" with Exchange protocol, an error appears: "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsiMsgAccountManager.createIncomingServer] Thx
