Troubleshooting Steps

  1. Make sure your Outlook version is at or above 14.0.7116.5000

    1. To see your Outlook version, click on File > Help > Additional Version and Copyright information. The number at top right is the one you're interested in.

  2. Run Windows Update and make sure all Office and Outlook patches are installed.

  3. Follow the directions below for running outlook with the /cleanfreebusy switch.


Run Outlook together with the /cleanfreebusy switch

Outlook has several command-line switches that you can use to repair issues. To repair free/busy, follow these steps:
  1. Close Outlook.
  2. To determine the path of Outlook.exe, follow these steps:
    1. Click Start, point to Find, and then click Files or Folders.
    2. In the Named box, type Outlook.exe, and then click Find Now.
    3. Note the path of the Outlook executable for reference.
      1. For Outlook 2007, the default path is C:\Program Files\Microsoft Office\Office12\Outlook.exe.
      2. For Outlook 2010, the default path is C:\Program Files\Microsoft Office\Office14\Outlook.exe.
    4. On the File menu, click Close.
  3. Click Start, and then click Run.
  4. In the Open box, type the path of Outlook (include the file name in the path), press the Spacebar one time, and then type /cleanfreebusy. 
    1. For example, the command-line command for Outlook 2010 is as follows:
      "C:\Program Files\Microsoft Office\Office14\Outlook.exe" /cleanfreebusy

      Note: The full path has to be in quotation marks to preserve long file names.
  5. Determine whether the problem still occurs.
