GO!NotifyLink Enterprise Server:

Issue: If you issue consecutive 'Notify Off' commands before issuing a 'Catchup' you will not receive any emails that where sent prior to the most recent 'Notify Off'. A timestamp is generated when the 'Notify Off' command is received and this time is used to determine which emails should be sent to the device when a 'Catchup' is received. As such, this timestamp gets reset each time a 'Notify Off' is received and any emails that were gleaned prior will not be sent.

Solution: There is no solution at this time.
