I want to automate the PST compaction process without any regular lookup and which should be based on my custom settings. How to do it?

Answer: The software provides a scheduler to schedule the compaction process to be held automatically at the specified Date and Time. The entire process will be based on your predefined custom settings and you need not have to lookup every day. You can schedule your compaction operations as below:

Steps to automate PST Compaction -

  • Run Stellar Phoenix Compact PST software and click the 'Settings' tab.
  • Chose the appropriate 'Compacting Options' and other options as per your requirement.
  • Under 'Compact Scheduler' section, check mark 'Schedule Settings for compact Outlook Data File'.
  • The 'Compact Scheduler' dialog box opens. You can choose between two distinguished options. If you want the software to run every day at Outlook start-up, check-mark the 'Start of MS Outlook' option under 'Everyday At' section. To run the software at any particular day, check mark the 'Compact Daily At' option and provide the details under 'Specified Day & Time'. Check mark the days, if you want the operation to be held in any specific day.
  • Click 'OK' to finish.

Note: You can see the scheduled tasks at Start menu > System Tools > Scheduled Tasks Folder.
