title: How can I get all the activities for an account?
body: <p>I have a program that I have written that gets the data from Dynamics CRM 2013 online. But I am running into one issue where a query to get the activities for an account only returns a subset instead of all the activities. The query expression is this</p>
  
  <pre><code>private QueryExpression CreateActivityQuery(Guid id)
  {
      QueryExpression query = new QueryExpression()
      {
          Distinct = true,
          EntityName = Cd2Sf.ActivityPointer.EntityLogicalName,
          ColumnSet = new ColumnSet(true)
      };
      query.Criteria = new FilterExpression();
      query.Criteria.AddCondition("regardingobjectid", ConditionOperator.Equal, id);
      return query;
  }
  </code></pre>
  
  <p>Where the id is the account id. I had first tried using the activityparty where the party id was equal to the account id and then I tried using the regardingobjectid and lastly then tried the Rollup method with the extended related entities but all produce the same result. </p>
  
  <pre><code>#region Create RollupRequest
  // Create RollupRequest
  RollupRequest rollupRequest = new RollupRequest();
  rollupRequest.Query = qexp;
  rollupRequest.Target = new EntityReference("account", acct.Id);
  rollupRequest.RollupType = RollupType.Extended;
  #endregion Create RollupRequest
  
  #region Execute RollupRequest
  // Execute RollupRequest
  RollupResponse rollupResponse = (RollupResponse)service.Execute(rollupRequest);
  #endregion Execute RollupRequest
  
  #region Show RollupResponse results
  ShowActivities(rollupResponse.EntityCollection, percent);
  #endregion Show RollupResponse results
  </code></pre>
  
  <p>Do I need to use contacts as well to get all the activities that are associated to the account, i.e. use the activityparty and match the to/from/sender/cc/bcc/etc with contacts for an account? I had tried to use the contact id as the regardingobjectid but that still does not account for all of the activities.</p>
  
  <p>It appears that the web page for dynamics crm online when viewing the account and the activities that are on that page are more than what the above query gets alone.</p>
  
  <p>How do I get the other activities, the ones that seem to be not directly related to the account?</p>
