We are planning a large deployment of Zimbra NE 7 and I want to resolve some issues.

I've seen that from the Briefcase, you can not create spreadsheets and presentations in the trial version. Can I enable this functionality? How ? Some documentation ?

We are very interested in the online edition of documents. What options are about the formats like OpenDocument or OpenXML? I really would like to receive an email with a document, edit it in the bag and return the e-mail with the modified document.

I've seen in a Zimbra 7 webinar the possibility of sending SMS notifications. Where I can find documentation about this?

Thanks for all,
