Please note: These numbers are based on the status of April 2023. Throughout 2023 email-content will no longer count towards data capacity impacting the potential savings. Learn more

The AttachmentExtractor for Dynamics 365 and PoweApps moves content (emails and files) from Dataverse to SharePoint or an AzureBlob. Doing so significantly reduces data and file capacity consumption. As a result, you save costs by avoiding expensive Capacity Add-ons for Dataverse.

The big question is: How much money can I save?

This article describes the steps to take to get a good idea of the potential savings for your tenant.

How to Estimate your data & file Capacity savings:

  1. First, go to the “Power Platform Admin Center” and log in to your tenant.
  2. Navigate to “Licensing” -> “Dataverse” ->”Environments“.
  3. Select your environment.

By scrolling down, you can find and open the ActivityPointerBase, Attachment, and AnnotationBase tables and view their size.

Now you can estimate your potential savings:

  1. Data Capacity Savings: Moving email content will shrink the ActivityPointerBase table around between 35-40%. Thus, we recommend 40% for your estimate.
  2. File Capacity Savings: Moving file attachments will shrink the Attachment and AnnotationBase table between 60-90%. Thus, we recommend 80% for your estimate.
