First of all thanks a lot for tnefparse, it rocks! It seems to be the only opensource util/library that has so far managed to parse this winmail.dat file I have here..

My question is: are there any plans to support generating .ics files from winmail.dat MAPI calender invitations? For example MS Exchange 2010 seems to send such winmail.dat files (and some organizations still seem to use such an old servers..). Based on some googling newer Exchange servers and/or Outlook clients might send such winmail.dat invitations aswell.

If I understand correctly such winmail.dat file does not include any real .ics attachments but instead the calender invitation is included in the MAPI fields/objects/properties.. like this:

$ tnefparse -o winmail.dat  -b
