Hi everybody.
Time to time I receive email with winmail.dat only in my Kontact client. Because I did not know what the sender made and why it happend I did not ask. BUT now I know and try to describe.
In Outlook2016 connected to Grommunio server exist some appointment at private Calendar. My collegue open this appointment and attach me in. Outlook sent email to my grommunio local account. At web GUI I can see appointment which I can confirm or reject. If I would like to export it to eml it save *.ics file which seems correct.
At my grommunio account I have rule which send all emails to my other address at Kolab server. Delivered email contains only winmail.dat. I can see it in Kontact client and Kolab WEB GUI too.
My Kontact client is connected into my grommunio account by IMAP TLS protcol. I can see winmail.dat only too at incomming message. So by WEB GUI I can see correct message but by IMAP winmail.dat only.
I checked log files at both servers, but did not find any error. Has somebody some idea how to discovered where could be problem?
Outlook is set to create new messages as HTML and convert to HTML other ones when reply or forward them.
Thank you for any advice.
