The Outlook for Windows message window that opens when you create a new message, reply to, or forward a message does not display all message fields. The most used options are available directly in the message composition window:

Having received a huge number of different promotions, discounts, last-minute offers, and limited time offers, we often check them when their validity period has already expired. To avoid missing such an offer or promotion, you can set reminders in Outlook. But it is also very useful to clean up, remove, or mark invalidated messages that are already overdue:

In Outlook, you can assign importance levels to outgoing messages so that recipients can quickly understand whether the message needs to be processed as soon as possible or can be left later.

For some Outlook messages, it can be useful to add Voting buttons to collect your colleagues' or friends' votes (see how to add and use voting button in Outlook). The sender of a message with voting buttons will receive an e-mail message each time the recipient votes on it.
