I recently downloaded Zimbra Desktop and I really like it. I'm admittedly not very technical. My problem is in Contacts; I cannot save new numbers in the mobile number field. I enter the new mobile number, it highlights in blue and appears saved. When finished, I move between Mail and Contacts and the number appears saved. I quit ZD then reopen it and the numbers are still there. HOWEVER if I turn off the computer, restart it and open ZD, the mobile numbers are gone. What am I doing wrong? How do I fix this?
