Set Vacation Out of Office in Outlook: Setup and Tips

To set a vacation out-of-office reply in Outlook, open Automatic Replies, turn them on, choose your dates, write your messages, and save. The exact menu depends on whether you use classic Outlook for Windows, new Outlook, Outlook on the web, or Outlook for Mac. Set it up before you leave, and send yourself a test message if you want to confirm the reply is working.

What You’ll Need

Access to the Outlook account that should send the reply. For work or school accounts, automatic replies are usually provided by Microsoft Exchange or Microsoft 365.
Your vacation start and end dates, including the times you want replies to begin and stop. Check your calendar and time zone before entering them.
A short message explaining when you will be away and what senders should do if their request is urgent. Have a separate external message ready if people outside your organization need different information.

Step-by-Step

Identify which Outlook you are using. Classic Outlook for Windows has a File tab at the top-left of the main window. New Outlook for Windows has a more web-like interface and a Settings gear. Outlook on the web runs in a browser, while Outlook for Mac has its own menu layout. Follow the matching route below; the wording and placement can change slightly with updates.
Open Automatic Replies. In classic Outlook for Windows, select File > Automatic Replies. If you do not see Automatic Replies, your account may not support the feature, or you may be using a different Outlook version. In new Outlook for Windows, select the Settings gear, then Accounts > Automatic replies, and select the account if asked. In Outlook on the web, select the Settings gear, then Accounts > Automatic replies. In Outlook for Mac, look under Tools > Automatic Replies; depending on the release, you may instead find the setting in Outlook > Settings > Accounts after selecting the account.
Turn on the automatic reply. In classic Outlook, choose Send automatic replies. In the newer interfaces, switch on Automatic replies or the equivalent control. If Outlook offers a choice between replying for a limited period and replying indefinitely, enable the scheduled-period option for a vacation. This helps prevent the message continuing after you return.
Enter the start and end times. Select the option to send replies only during a specified time period, then set the beginning and ending dates and times. Use the time zone associated with the mailbox or the one shown in Outlook’s date controls, and consider whether you want the reply to start before your first day away. Set the end to a time when you are actually ready to receive messages again. If you are unsure, choose a slightly later end time and add a return date in the message so senders have a realistic expectation.
Write the message for people inside your organization. In classic Outlook, use the Inside My Organization tab. In other versions, enter the internal message in the available reply box. State the dates you will be away, when you expect to respond, and the correct backup contact or shared mailbox for urgent matters. Keep it brief and specific. For example: “I’m away from June 10 through June 14 and will respond when I return on June 17. For urgent order questions, contact Jordan Lee at the sales desk.” Check that the dates and contact details are correct before saving.
Decide whether to send a separate external reply. If senders outside your organization should receive an answer, enable external replies. Classic Outlook separates this into an Outside My Organization tab. New Outlook and the web version may offer a choice to reply only to contacts or to everyone outside the organization. Choose the narrower contacts option if it meets your needs; replying to everyone can disclose your absence to unfamiliar senders. Do not include sensitive travel plans, personal phone numbers, or details that you would not want forwarded.
Review the external message and audience. Use a shorter message for external recipients if appropriate. You might say that you are unavailable until a specified date and direct customers to a general team address. In classic Outlook, the outside-organization setting may include a checkbox controlling whether replies go only to contacts. Read that option carefully: it affects who receives the message, not just how the message is worded. If you do not need external replies, leave them off.
Save or apply the settings. In classic Outlook, select OK. In new Outlook or Outlook on the web, select Save if shown, or close the panel only after confirming the setting has been applied. Outlook for Mac may use an OK or close control. Reopen Automatic Replies to verify the toggle, schedule, and message are still present. A drafted message is not active until the setting is enabled and saved.
Test the result. From a different email address, send a simple message to the account and confirm that the expected reply arrives. If the scheduled start is in the future, the test may not trigger yet; do not change the date just to test unless you can restore it immediately. You can instead check the saved settings and ask a colleague to confirm the message after the scheduled start. Remember that Outlook may send only one automatic reply to the same sender during a period, so repeated tests from one address may not generate repeated replies.
Turn the reply off when you return if needed. If you set an end time, Outlook should stop replying then. If your return plans change, revisit Automatic Replies and adjust the schedule or turn the feature off. You can also update the message if your return date or backup contact changes. Do not assume that closing the Outlook app turns off a reply; for supported Exchange and Microsoft 365 accounts, the automatic response is generally handled by the mail service.

Common Mistakes

Forgetting to enable the feature. Typing a message into the box does not necessarily activate it. Check that the main switch or “Send automatic replies” option is on and that you applied the changes.

Leaving the end date unset. An indefinite reply can continue after you return. Use the scheduled-period option where available, and verify the end date and time before you leave.

Choosing the wrong account. If Outlook contains personal and work mailboxes, settings may apply to only one account. Check the account name shown in the Automatic Replies panel, especially if you manage more than one inbox.

Assuming external replies are enabled. Some versions keep outside-organization replies separate from internal ones, and they may be off by default. Confirm the external audience setting if customers or other outside senders need a response.

Sharing too much information. A vacation reply may go to people you do not know. Avoid telling strangers that your home will be empty, listing detailed travel plans, or sharing confidential work information. Provide a general return date and an appropriate business contact instead.

Using a rule as if it were an automatic reply. Rules that send a reply from a template are not the same as the mailbox’s Automatic Replies feature. They can behave differently, may require Outlook to remain running, and can create reply loops. Use the built-in feature when your account supports it.

Tips

Keep the reply useful rather than elaborate. A good message answers three questions: Are you available, when are you expected back, and whom should the sender contact instead? If there is no backup person, say when you will respond rather than promising a response time you cannot guarantee.

Use separate internal and external messages when your organization’s policies allow it. Coworkers may need a colleague’s name or team channel, while external senders may be better directed to a public support address. If the external audience is broad, avoid a personal mobile number unless your organization specifically approves sharing it.

Check the calendar invitation and mailbox schedule if you work across time zones. The automatic reply is tied to a mailbox’s date and time settings, and a difference between your travel location and work location can make the message start or end earlier than expected. Make the return date explicit in the text as well as setting the end time.

For a shared mailbox, confirm that you have permission to manage its automatic replies and that you are editing the shared mailbox rather than your own account. If you cannot find the setting or save changes, ask your Microsoft 365 administrator. Company policies may also specify a standard message or approved backup contact.

On the Outlook mobile app, open the account menu or profile, select the relevant account, and look for Automatic replies in its settings. The exact labels can vary by app version and account type. If you cannot find the control on your phone, use Outlook on the web or desktop instead, then verify the saved setting there.

Troubleshooting

Automatic Replies is missing. The feature is commonly available for Exchange, Microsoft 365 work or school, and Outlook.com accounts, but not every email provider supports it. If the mailbox uses IMAP or POP, Outlook may not be able to set a server-side vacation reply. Check with the email provider for its webmail vacation-response setting, or ask your work administrator whether the feature is enabled. Do not assume that an Outlook rule will work while your computer is off.

No reply arrives during a test. First verify that automatic replies are enabled, the test time falls inside the scheduled window, and the message was saved for the account you emailed. Check the Junk or Spam folder at the test address. Send from a different address, because Outlook may limit repeated replies to the same sender. Also check that you are testing the correct internal or external message; an external sender will not receive an internal-only reply.

The reply starts or ends at the wrong time. Reopen the schedule and confirm the date, time, and mailbox time zone. If you changed your computer’s time zone while travelling, compare the setting with the mailbox’s intended local time. Update both the schedule and the dates written in the message so they do not contradict each other.

Only some people receive a reply. Review the external audience option. A setting limited to contacts will not reply to every outside sender, and an internal message is not sent to external addresses. Ask a colleague to test from inside the organization and use a non-work address for the external test.

The setting will not save or the menus look different. Confirm you are online, reopen Outlook, and try Outlook on the web for the same account. In a managed work account, an administrator may restrict the feature. If the control is still unavailable, provide IT support with the account type, Outlook version, and the exact step where saving fails; never send them your password.

Frequently Asked Questions

Will Outlook send the vacation reply if my computer is off?
For supported Exchange, Microsoft 365, and Outlook.com accounts, the automatic reply is generally managed by the mail service, so Outlook does not need to stay open. A local rule that sends a template may behave differently and can depend on Outlook running.

Can I set automatic replies for only certain dates?
Yes. Turn on the scheduled-period option and enter a start and end time. Check that the date range matches the dates in your message, and remember that the time zone can affect when the reply begins or stops.

Does Outlook reply to every email from the same person?
Usually not. Outlook commonly sends one automatic reply to a sender during the active period rather than replying to every message they send. This prevents repeated responses and mail loops, so use a different address when testing.

Can I send one message to coworkers and another to customers?
Yes, when your Outlook version provides separate internal and external message areas. Write each for its intended audience and check the external audience setting. Some versions let you limit outside replies to your contacts.

How do I stop the reply early?
Open Automatic Replies for the correct account and turn the feature off, then save or apply the change. If you have multiple mailboxes, check each one; turning it off for your personal account does not necessarily change a shared mailbox.

Why can’t I find Automatic Replies in Outlook?
Your email account may not support Outlook’s built-in feature, or the control may be in a different place in your version. Try the account settings in Outlook on the web, check the provider’s vacation-response settings, or ask your administrator whether the feature is available.
