Refresh Maintenance Date for the Product Key
If the maintenance date for your product key is not up-to-date, refresh the product key. Refreshing the product key will update the product key with the date that your current maintenance period expires and stops expiration messages you may have already received. If you believe that the latest displayed date is incorrect, contact Tableau Support.
Note: This topic describes how to refresh the maintenance date for Tableau Server. For information about refreshing the maintenance date on Tableau Desktop see Refreshing Tableau Desktop Product Key in the Tableau Knowledge Base.
