crpb I am using the appliance from the 16-02 ISO so not a Debian update. If this is showing up on Debian and OpenSuse it is likely the gromox update 2.26.152.g05ad038-lp155.39.1 caused the issue as I believe that it handles the http code.
I have just applied this mornings updates to my 16-02 ISO appliance :-

As you can see below no change in the errors. Also the 'ews: unknown field URI 'message:ReplyTo' (ignored)' message is also still being reported own the http log (this has been happening for about 4 weeks now.

Both log messages appear to be benign, but just because Grommunio seems to be working OK, doesn't mean a pending issue isn't developing. it would be nice to clear these error/info/warning log entries, whatever they are.
