Zimbra Forums

I am having continuous errors with "Zimbra Desktop is unable to synchronize data from "xxxx@gmail.com". Re-enter the password and click Save to re-authenticate the account." It gives an entry line for the password and two buttons SAVE and DISMISS. These errors occur for all of my gmail accounts. I have also noted the loss of the Calendar and Contacts synchronization with my Yahoo and GMail accounts. These were big reasons for my using this application in the first place. When might they be re-implemented or restored to the program?
