Outlook reminds you of due tasks and appointments, automatically fetches your e-mails etc. And numerous Addons depend on that Outlook is running. Of course, all of the functions are only available as long as you don't close Outlook.


  • Determine how Outlook should react to clicks on the Close button or the cross in the upper right corner.
  • Before Outlook actually closes, OLKeeper asks you what to do: just minimize the window, really close it or cancel.
  • You will never again miss an important appointment or e-mail just because Outlook was accidentally closed.
  • Don't waste your time with unnecessary, long waits during Outlook restarts.
  • You can configure OLKeeper to prevent employees from closing Outlook.
