I'm currently busy with a new project. That is an integration between Zimbra and ERP (openbravo).
I have already searched for information from Zimbra. (the docs folder in Zimbra) and some guides.

What i have to do (in summary) are these steps:
1] That users can make new emails/calendar items and task outside zimbra
2] And get these new emails/calendar items and task from Zimbra.

It is unfortunaly not easy to get for example tasks in Zimbra. Is this possible via SOAP of maby another way?

And do you have maby another ideas/information or method to get information from and to Zimbra?

Thanks in advance!
