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. Some email clients, providers, or organizations may be configured to send low-importance emails only during non-business hours.

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.

Voting Buttons in Outlook are a useful feature that helps you easily collect your colleagues' or friends' opinions, preferences, or decisions through email messages. Using Voting Buttons in email messages, you can create a poll, survey or just ask questions with a limited set of answers.

On replies to emails, the response (replying message) is returned, by default, to the sender of the email. In some business processes or projects, creating messages with responses collected by someone other than the message creator is often necessary.

Nearly every home and business Internet provider also offers an e-mail service. In Outlook, you can connect one or more email addresses from both Microsoft and other providers. To organize your email addresses in Outlook, you can create different profiles.

Currently, Outlook for Web messages text is created in the 12-point black Aptos font. You can use the default font and then apply different fonts, styles, and formatting options for characters, paragraphs, and more in Outlook for Web messages (just as you do in other Microsoft applications, such as Word or PowerPoint):

By default, text in Outlook messages is shown in 11-point Calibri, black for original messages and blue for responses, arranged in left-aligned paragraphs on a white background. In Outlook messages, you can apply two types of formatting at the same time:
