Hello, After transfering mail (with Thunderbird), the receiver tells me that the original text transferred is missing in my mail. Mail server is outlook exchange, and I can confirm the missing text when looking via webmail, in sent file. Strange, because thunderbird shows original text, even in the receiver's answer. When selecting only text format in thunderbird preference, original text is transferred, so I guess the problem is in the HTML protocol. I'm using TbSync and ActiveSync for Exchange Thanks for your help
