I am constantly having issues accessing my Google Apps Mail. Sometimes it will sync just fine. There are other times where I get and error that says “Synchronizing folder failed due to the following error: Execution of request failed (Temporary Problem - please try again later)” This happens half the time I try to sync my mail.
When this error pops up again, could you please open the third tab in the same window as the error titled ‘Log’ and copy its content here? (For fast copying, pressing Ctrl+A will select everything).
