Learn how to setup an out of office reply in Outlook
Description: Set up automatic replies, set a time range, use rules to manage your inbox while you’re out, and create different out-of-office messages for different groups, with or without a Microsoft Exchange account.
Click the File tab.
Then Info tab in the menu.
And now the Automatic Replies (Out of Office)
In the Automatic Replies dialog box, select the Send Automatic Replies check box.
If you want to specify a set time and date range, select the Only send during this time range check box. Then set the Start time, and then set the End time.
In the Inside my organization tab, type the message that you want to send within your organization, and in the Outside my organization tab, type the message that you want to send outside your organization.
Click OK.
If you selected the “Only send during this time range” option, the Automatic Replies (Out of Office) feature will continue to run until the date and time set for the End Time is reached.
Otherwise, the Automatic Replies (Out of Office) will continue to run until you repeat the setup and select the “Do not send automatic replies” option.
