hello outlook gurus
a few w7x64/outlook 2010 sp1 clients are unable to open digitally signed emails. the same user can open these emails on a different client with outlook 2010 or in owa. i already tried to create a new outlook profile, but i had the same problem.
they get the following message: this element can not be opened, because of an unknow error. (translated from german).
any ideas where to start the troubleshooting process ? thanx alot .
hubert
ps: i already cleard the corresponding certificate in the w7 cert-store.
