Hello,

I have already ticket open but I'm wondering if anyone else experienced issues with message corruption for emails delivered from outlook.com servers. I have few clients which are getting corrupted messages and one thing in common for them (except similar corruption) is that all of those messages has been sent from outlook.com servers.

All of this messages starts (in message content view) like:

and later there is some base64 encoded message.

Thanks

CodeTwo is a company that adds a standardized closing signature and footer to every message. If all of the messages are from CodeTwo, I would suggest contacting them

Only one corrupted email had codetwo entries in headers but still. All of those corrupted emails sent somewhere else are being shown correctly. I had my client asked his client to send email to his SmarterMail account and GMail account as second email and one received in SmarterMail is corrupted and in Gmail is not.

FYI this has been confirmed as a bug and will be resolved but I'm not sure in which of future builds
