The auto-reply message is sent to each recipient only once, regardless of how many messages that person sends you during the designated vacation period.

1. Click the Preferences tab.
2. Click the Mail tab. The Mail tab appears.
3. Scroll down to the Receiving Messages area, as shown below.
4. Check Send auto-reply message.
5. Enter the message to be sent in the text box, such as the message shown above.
6. Check Start Date.
7. Click the arrow to open the calendar, and select the start for the away message.
8. Check End Date.
9. Click the arrow to open the calendar, and select the end for the away message. The End Date is the last date (inclusive) that the away message is sent.
