The contents of the Public Folder Favorites folder are not removed from your offline folder files when you turn off the Download Public Folder Favorites option in Outlook


Symptoms


If you turn off the Download Public Folder Favorites option in Outlook 2003 or in Outlook 2007, the contents of the Public Folder Favorites folder are not removed from your offline folder files (.ost).

Cause


This behavior occurs because all future synchronization stops when you turn off the Download Public Folder Favorites option. This prevents the .ost from receiving new files and growing larger, but it does not remove the files that have already been downloaded.

Workaround


To work around this behavior, turn off the Download Public Folder Favorites option, and then clear offline items from each
Public Folder Favorite folder that is in your .ost. To do this, follow these steps:
  1. Start Outlook.
  2. Click Tools, click E-Mail Accounts, click View or change existing e-mail accounts, and then click Next.
  3. In the Name list, click your Microsoft Exchange server, and then click Change.
  4. Click More Settings, and then click the
    Advanced tab.
  5. Under Cached Exchange Mode Settings, click to clear the Download Public Folder Favorites check box, and then click OK.
  6. In the Outlook navigation pane, right-click a Public Folder Favorites folder, and then click Properties.
  7. On the General tab, click Clear Offline Items.
  8. Repeat steps 6 and 7 for each Public Folder Favorites folder that you want to clear.
