Comment 17 for bug 247396

I have the same problem.

After installing 'evolution-plugins-experimental', ensuring 'tnef-attachment' is enabled, and restarting machine, "winmail.dat" attachments are not recognised.

I have updated all packages via 'apt-get upgrade'. dpkg -l evolution\* yields:

Any suggestions appreciated
