Rebuilding search index

If you search for items in Microsoft Office Outlook 2007 and 2010 and do not receive the results that you expect, the indexing of your Microsoft Windows and Microsoft Office system data files (the search catalog) may not be complete.
Symptoms of an incomplete index include the following:
  • Partial or no search results are returned.
  • Items that you expect to appear based on your search criteria are not displayed.
You can rebuild the search catalog, which restarts the indexing of your data files. The search catalog is a file where all of your Outlook and Microsoft Windows items (data files) are indexed. To rebuild your search catalog, do the following:
  1. Exit Outlook.
  2. In Microsoft Windows, click the Start button, and then click Control Panel.
  3. Do one of the following:
    • Windows Vista Click System Maintenance, and then click Indexing Options.
Note In Classic view, double-click Indexing Options.
  • Microsoft Windows XP Under See Also, click Other Control Panel Options, and then click Indexing Options.
Note In Classic view, double-click Indexing Options.
  1. Click Modify, select the check boxes for the locations you want to index, and then click OK.

Use Outlook in Cache and Online Global Address List

You can use Outlook in cache mode and still have the client access the Global Address Book online:
If you make frequent changes to the offline address book, you may want to modify the way that Outlook computers on your network access the Address Book. You can disable the downloading of the offline address book and force the Outlook computers to use the online Global Address List when they use Cached Exchange Mode.
To do this, add the following registry value to the computers, as appropriate for the version of Outlook that you are running.
Outlook 2010
HKEY_CURRENT_USERSoftwareMicrosoftOffice14.0OutlookCached Mode
Parameter: DownloadOAB
Type: REG_DWORD
Value: 0
Outlook 2007
HKEY_CURRENT_USERSoftwareMicrosoftOffice12.0OutlookCached Mode
Parameter: DownloadOAB
Type: REG_DWORD
Value: 0
 
We highly recommend Cache mode for outlook users for the reasons stated in the blog site below:
