Enable email previewing
harmon.ie for Outlook Knowledge Base
The Show Preview command allows you to see a preview of email messages (.msg files) uploaded to SharePoint using:
Messages uploaded using the Upload button or by dragging and dropping from the Windows Explorer cannot be previewed.
For previewing email messages, harmon.ie saves the content of the email in a column named MailPreviewData.
The content is compressed and stripped from embedded objects, such as images, excel tables, etc.
To enable the preview of email messages:
The MailPreviewData column must be added to the SharePoint library and to the content type assigned to email messages. There are two methods to add it:
- Create a column called MailPreviewData in the SharePoint library.
- Set Column type to Multiple lines of text, with plain text.
- Set Allow unlimited length in document libraries to Yes.
- Uncheck Add to all content types (recommended).
- Uncheck Add to default view, in order to hide the column from the library view (recommended).
- Add this column to the content type assigned to email messages.
- Select the column from the content type and set This column is to Hidden, to hide the column from the document properties (recommended).
- By configuring email header mapping. Read Automatic configuration of mapping email headers to SharePoint properties and email headers search to learn how.
