A family of Microsoft word processing software products for creating web, email, and print documents.
From the three-dot handle in the screenshot, I can see that the selected item is a content control, but I can't tell what kind of content control it is; I'll assume it's plain text. Also, I can't see what the control displays before it pulls the data from the CRM database. Anyway, this works for me:
Click on the three-dot handle to select the whole control (but not the table cell that contains it). Press Ctrl+F9 to insert field braces around the control's contents. Between the opening brace and the original contents, type the word DATE, a space, and a double quote mark. Between the original contents and the closing brace, type a double quote mark, a space, and the switch @ "yy". It should look something like this:
{ DATE "27/8/2019" @ "yy" }
Press F9 to update the field and display its result, which in this case will be 19. (If you really meant that you want the day, month, and two-digit year. the switch should be @ "dd/MM/yy".)
