Sharepoint - Adding a comment

You need a reliable “sent to client” date, while the Properties form no longer displays your former Comment field. SharePoint’s editable properties depend on the library’s configured columns and your permissions, so a shorter form does not by itself prove the information was deleted. Select an affected file and open the library’s Details pane, then Edit all, to check its available metadata. Ask the library owner to check the existing Comment column before creating a replacement. For the actual requirement, add a Date and time column named “Date sent to client,” configured for date only if time is unnecessary. Enter the value through the Details pane and add the column to the library view so it can be sorted and filtered. If you cannot create columns or edit values, the library owner needs to check your permissions and column configuration.
