User Permissions for creating Exchange/AD Tasks

I am trying to disribuite small tasks to users to alleviate pressure from our IT Dept.  In this case, I am trying to set it so users can add Exchange/AD contacts.  Here is what I am getting for an error report:

- <taskWizardRun taskName="Establish E-mail Address" dcName="CUTTER_JOHN" buildNumber="6944" runningAs="adminit@uwc21.net">
  <timespan startTime="2007-03-28 14:41:58.006" milliseconds="15" />
  <taskSummary errorCount="1" completedCount="0" warningCount="0" errorCode="0x00000000" />
- <items>
- <item adsPath="LDAP://cutter_john.uwc21.net/CN=Test Test,OU=UWC,DC=uwc21,DC=net" class="contact">
  <progress code="10" milliseconds="15">Updating attributes</progress>

  </noWriteAccess>
  </details>
  </summary>
  </item>
  </items>
  </taskWizardRun>

Any ideas?
