If you want to prompt others to act on or respond to an email message, you can send a reminder for the recipients with a flagged message. Another option is to send a message that is flagged with start and due dates and more information in the Flag to list. This way, the information is available to the recipients in the InfoBar of the message, without a reminder.
Note*** Use discretion when you send reminders to other people. Some recipients might not want reminders to appear on their screen while they work.
1. In a new message, on the [Message] tab, in the [Tags] group, click [Follow Up], then click [Add Reminder].
2. When a new window appears, select the type of reminder that you want in the Flag to list.
3. Select a date and time in the lists next to the Reminder check box. The reminder type, together with the date and time, appear in the InfoBar of the message.
