Synchronizing Error

Hi, I am getting the following error. Do not know what it means. How do I correct the problem?

8:32:26 AM MailClient.Storage.Application.OperationException: Synchronizing folder ‘3 - UD/Directory/’ failed due to the following error: Execution of request failed: https://www.google.com/m8/feeds/gal/u… (Temporary problem - please try again later.)

I have seen this error in the past and it was what it said-- a temporary Gmail problem that cleared on its own.
