Unable to Delete Attachments from Completed and Read-Only Email Records

What’s happening?

Users are unable to delete attachments from incoming email records in Dynamics 365 once the email record status is marked as "completed" and becomes read-only.

Reason:

In Dynamics 365, email records marked as "completed" become read-only, which inherently prevents any further modifications, including the deletion of attachments.

Resolution:

In Dynamics 365, deleting attachments from a read-only email record is not directly supported due to the inherent restrictions on modifying read-only records. However, this functionality can potentially be achieved through additional customization methods, such as:

• Implementing a custom workflow.
• Developing a plugin.
• Utilizing Power Automate (formerly Microsoft Flow) to automate the deletion process.

These customization methods can provide a workaround to delete attachments from email records that are marked as completed and read-only.
