Outlook cannot be running to use the purge/compact functionalities. This program will compact and purge MDaemon Connector database file.  There are four main command line options:
                
(1) Use the /f command line option to specify the location of the database file, LocalCache.db. This option is required for both the compact and purge options.
                
(2) Use the /c command line option to compact the database file, Localcache.db. Use the /s switch to specify the cache size.  Use the /g switch to specify the page size.
                
(3) Use the /p command line option to purge the message body of mail messages and purge orphaned attachment files.  Use the /d switch to specify the age of the file.
                
(4) Use the /? command line option for additional information about the available command line options

(1) A crash occurs when Outlook tries to sign or encrypt a plain text or RTF message using
                Outlook 2016 and Windows 10.
                
(2) Embedded S/MIME encrypted message within sent encrypted S/MIME message
                will have blank message body.
