1. Just get your root certificate installed on the device so that it is seen in the certificate store (server sertificate!), lot of instructions to do that on this forum.. 2. Go to xterm: cd /home/user/.maemosec-certs/ssl-ca/ 3. see the directory contents: ls -lh ; there should be a long file (something like x89x8x7087873234324.pem and then a short symlink to it 89737443.pem ) 4. then just make the symlink: cd /home/user/.activesync/certs/ ln -s /home/user/.maemosec-certs/ssl-ca/* . this did the trick for me! But do this on your responsibility!
