        Hi,
it's not the evolution-ews, but the Exchange server having problem
convert the message into the MIME version. I mean, the error above is
returned by the server, after the evolution-ews requested the server to
return the message as its MIME version, not as a set of properties.

Some versions of the Exchange server support only S/MIME, not PGP,
which sort of explains the issue.

I tried to copy couple PGP messages into an Exchange 2007 server (using
evolution-ews) and it garbles the messages which are encrypted, not
those signed only. I tried the same messages with an Exchange 2013
server and it works fine there, all the messages look the same as in
their source directory.

I do not know how much the actual result depends on the method the
message was received (either by copying, as in my case, or by a SMTP,
like probably in your case), but I cannot try the encrypted messages, I
do not have the right GPG key.

Thinking of it, the curl command I offered you to provide will not
help, it will return the same error, thus the only way to correct this
is to fallback to "construct message from properties on the client
side, instead of relying on the to-MIME conversion on the server), but
I cannot reproduce the error with my copied messages, they all are
downloaded, even shown garbled in case of the encrypted message.
        Bye,
