My system is win2k8 64 bit, I have outlook 2010 64 bit installed and I tried to install ZCO with ZimbraConnectorOLK_220.127.116.1124_x64.msi.
After installation and configured profile, whenever I started outlook I saw error
"Cannot open your default e-mail folder. An unexpected error has occurred. MAPI was unable to load the information service LSMSSP.DLL. Be sure the service is correctly installed and configured."
