I have tried to download email from an imap account successfully using vb.net and EAGetMail, emails are saved to a folder as .msg. The problem is when I open one of those files with Outlook (tested only with 2016 version) and I try to reply to all, from address appears on to destinations. If I try that with a msg file saved by Outlook not by EAGetMail the reply to all is ok and from address doesn't appear on to destinations.
I'm using evaluation version of EAGetMail, ¿is it a limitation or a bug?

thanks for reporting this problem, we will do a test and will back to you at tomorrow.

Hi, we have tested it. When outlook save the email, if the sender is an account existed in outlook, the message will be marked as self-sent, so when you click reply all, from will not be included in the destinations, however, when you use EAGetMail save the email, EAGetMail doesn't know if sender is an account existed in local outlook, so when you click reply all, from will be included in the destinations.

That is not a bug or limit.

Thanks, that solves the question. It would be possible to include an option on a future version to mark email as self-sent? Something like this:

Ok, we will consider to add this feature at next version, but it cannot be done in very soon.
