Outlook is a popular email and calendar program. It can be difficult to compact Outlook data files, especially if the data is spread out across several folders. This article will show you how to easily compact Outlook data files.

  1. Open Outlook and click on the File menu.
  2. Select Compact Data from the menu and then click on the Compact Data button.
  3. In the resulting window, enter a name for your compressed Outlook data file and click on the OK button.

Of course this tip isn’t very useful for experienced Outlook users, but we like to cover everything helpful even if it’s fairly basic.

Compacting Outlook Data Files

From the Outlook main window, choose Data File Management from the File menu.

The Account Settings dialog will open up on the Data Files tab. Highlight Personal Folders, which should be located on the local drive, then click on the Settings button.

 

Now with the Personal Folders dialog box open, click on Compact Now.

A message indicating compacting is taking place will pop up then disappear when done. Now we can close out of the remaining windows.

This will work in both Outlook 2007 and 2003. If you notice Outlook becoming slow try out this quick fix.
