Slow+search+in+Outlook+2012

Problem:
Outlook 2012 is sometimes slow to provide results when searching emails

Solution:
Outlook 2012 uses the Windows 7 search so you need to rebuild the search index in Windows 7. Rebuilding the index can take several hours, and searches might be incomplete until the index is fully rebuilt.  
 * 1)  Open Indexing Options by clicking the Start button and then clicking Control Panel.
 * 2)  In the search box, type indexing options, and then click Indexing Options.
 * 3) Click Advanced.
 * 4) In the Advanced Options dialog box, click the Index Settings tab, and then click Rebuild.
