any help would be very appreciate.

I don't know if it's the right place to make this post. I new with Zimbra and I realized that is a very good application for document and information sharing. It's a great help with office collaboration life.

I need to enable preview on Zimbra 7.2.3_GA_2872_Ubuntu_10_64 FOSS EDITION in a fresh Ubuntu 10 install. so I followed the procedure

su - zimbra
zmprov gc default | grep zimbraFeatureBriefcasesEnabled
zmprov mc default zimbraFeatureBriefcasesEnabled TRUE

But after restarting, i still can't preview imported .doc .docx .xls documents.

Thanks and kind regards
