We are using ZCS release 7.2.0 on a CentOS 5.9 machine. I have one user who is using Outlook 2010. He has two email accounts. Each email account has a .pst file and neither one is backed-up by our back-up software most probably due to corruption in the files. Microsoft says that a .pst file "contains your e-mail messages, calendars, contracts, tasks and notes." I believe that Zimbra actually stores all of his emails on the Zimbra Server. Maybe, a copy of each email is stored in the .pst file but the actual email is still stored on the Zimbra Server. Am I correct?
Also, if this user creates any folder in Outlook and stores emails there, would the emails also be on the Zimbra Server or would they be taken off the Zimbra Server and put into the .pst file?
