Choosing to use Purview Sync or Collect

Purview Sync is a more sophisticated search capability than the MS Graph API. For customers who want to limit their search results they should use Purview Sync. For broader searches and imports using general date range or file types, you can use Collect.

You must have an E5 license to collect Teams data and email archives using Collect. For more information, see Collect. You need an E5 license for Advanced Discovery in Purview. For more information, see Importing data.
