Recently, during some forwarding/replying of emails, I get an error message. Sometimes it takes me 3-4 times at canceling the draft, then reopening the original email then clicking forward/reply until it finally will work without an error message. Please see attached pictures for the error messages. 
Hello,
please contact me on [email protected] together with link to this topic in subject.
with regards
Jan
