It also doesn't work well with contacts in Outlook 20 since editing the first page of the form reverts the form to the older Outlook contact form (as in the screenshot below). Note that the custom forms method doesn't work well with Appointment forms since you can't change the first page of the form. See the Tools section below for add-ins that you can use instead. (Home or Page Up jumps to the top entry on the list while End or Page Down jumps to the bottom.) If that is still too many steps, you can use a macro to insert the date and time. To insert other formats, use the arrow keys to select them, then press Enter. It's not bad if you use the keyboard shortcuts: Alt+N, D, Enter will insert the date and time format you have set as default. One complaint about the Insert Date & Time command is that it is too many steps.
