After installing a temporary license, Symantec Mail Security for Microsoft Exchange (SMSMSE) still shows "Expired" in the console.
The licensing display in the SMSMSE console will show "Expired" when a license is in its grace period. It will show "Not Licensed" when the grace period has ended. If the new temporary file covers less time period than the remaining grace period, the licensing status will not change in the console when the new license is installed.
The dates listed in the XML Symantec License File (*.slf) indicate the date at which the license will no longer activate product functionality.
The license file can be opened in Notepad to determine the actual end date. License files will be located in (by default) C:\ProgramData\Symantec Shared\Licenses, with the format *.slf.
