saved emails preview file attachment
When opening a saved email in a folder from the sharepoint web interface, the content of the email is displayed but not its file attachments. We would need a way to open the attachments. Right now the only way is through the desktop file explorer with synced folders.
This is a generic problem with storing emails containing attachments in SharePoint. There is no item on the roadmap that addresses this. There are 3rd party solutions (e.g. https://www.slimapplications.com/wp-content/uploads/2021/04/EmailManagerAttachmentPreview-1.png) that allow viewing of the attachments directly in the browser but Microsoft should offer this capability OOTB.
