How to Set Up an Out of Office Rule in Microsoft Outlook

To set up out-of-office replies in Outlook, use Automatic Replies if your account supports it: open the feature, write your message, choose when it should run, and save. This is usually more reliable than creating a mail rule because Exchange and Microsoft 365 can send replies while Outlook is closed. Use a reply rule only when Automatic Replies is unavailable, such as with some POP or IMAP accounts.

Outlook’s built-in feature is often called Automatic Replies rather than an out-of-office rule. The steps below cover both the built-in setting and a rule-based workaround, so you can choose the method that matches your account.

What You’ll Need

Access to the Outlook account you want to configure. For the built-in Automatic Replies feature, the account generally needs to be a Microsoft Exchange or Microsoft 365 work or school account.
Your planned absence dates and the message you want people to receive. Prepare separate internal and external messages if you need to share different details with colleagues and outside senders.
If you must use a rule, classic Outlook for Windows and permission to save an Outlook template file. The desktop app may need to stay open and connected for this workaround to reply to new messages.

Step-by-Step

Check which Outlook version and account you’re using. In Outlook for Microsoft 365 on Windows, look for the version switch or the simplified ribbon. The built-in feature is available for many work and school accounts but may not appear for POP or IMAP accounts. If you use Outlook on the web, sign in to the mailbox in your browser. If you have several mailboxes, select the one that should send the replies before changing settings.
Open Automatic Replies. In classic Outlook for Windows, select File > Automatic Replies. In new Outlook for Windows or Outlook on the web, select Settings (the gear) and then Accounts > Automatic replies. The exact label can differ slightly as Microsoft updates the interface. In classic Outlook for Mac, open Tools > Automatic Replies; in new Outlook for Mac, check Settings > Accounts for the same option. If the setting is missing, try Outlook on the web or use the rule workaround below.
Turn on replies and set a schedule. Select the option to turn on automatic replies. If you want Outlook to start and stop without you returning to the settings, enable Send replies only during a time period or the similarly named scheduling option. Enter the start and end dates and times, and check the time zone shown for the mailbox. If you do not set a time period, remember to switch replies off manually when you return.
Write the message for people inside your organization. Enter a concise note in the internal message box, if one is provided. State when you are away, when you expect to respond, and who can help with urgent matters. For example: I’m away from November 10 through November 14 and will respond when I return. For order questions, contact Jordan Lee at the support desk. Avoid promising a response time you cannot meet, and do not include sensitive information that should not be shared broadly.
Choose whether to reply to people outside your organization. Enable the external-sender option only if outside contacts need to know you are unavailable. Depending on the Outlook version, you may be able to reply to all external senders or only people in your contacts. Use a shorter external message where appropriate, and do not reveal internal staffing details, private phone numbers, or confidential project information. If your workplace disables external replies, ask your Microsoft 365 administrator rather than trying to bypass the policy.
Save the setting and verify it. Select Save or OK, depending on the version. Reopen Automatic Replies and confirm that the status and schedule are correct. If the absence is scheduled for later, the setting can show as enabled even though the reply will not start until the specified time. After the start time, ask a trusted colleague outside your organization to send a simple test message if external replies matter; do not use confidential content for the test.
If Automatic Replies is unavailable, create a reply template. In classic Outlook for Windows, create a new email containing the response, then select File > Save As. Choose Outlook Template (*.oft) as the file type, give it a clear name, and save it. Close the draft without sending it. This template will be selected in the rule you create next. Keep the message short and include an alternative contact if that is useful.
Create a rule that uses the template. In classic Outlook for Windows, go to File > Manage Rules & Alerts > New Rule. Under starting from a blank rule, choose Apply rule on messages I receive, then select Next. To reply to every incoming message, leave the conditions unchecked and confirm that you want the rule to apply to all messages. Select the action reply using a specific template, click the underlined template link, choose User Templates in File System, and select the saved .oft file. Continue through the wizard, add a name, and make sure Turn on this rule is selected before finishing.
Check how the rule will run. A template-reply rule is not the same as server-based Automatic Replies. It is generally a client-side rule, so classic Outlook may need to remain open, online, and connected to the account to process messages. Test it with a message from another account. If the rule is intended to run only during a particular absence, disable it when you return; unlike the scheduled Automatic Replies setting, the rule does not necessarily switch itself off on an end date.

Common Mistakes

Setting both methods at once: If Automatic Replies and a template-reply rule are both active, people may receive duplicate or confusing responses. Choose one method for the same mailbox and period unless your administrator has told you otherwise.
Forgetting the end date or switch-off: An unscheduled reply can continue after you return. Set a definite end time or add a reminder to turn it off.
Using a rule with Outlook closed: A client-side rule cannot reliably respond when the computer is shut down, Outlook is closed, or the app is disconnected. Use server-based Automatic Replies if your account supports it.
Sending too much information externally: External replies can reach customers, vendors, and unknown senders. Keep the message appropriate for a broad audience.
Assuming a rule behaves like an absence setting: A rule may not offer a schedule, separate internal and external messages, or the same safeguards against repeated replies. Review its behavior before relying on it.

Tips

Use clear dates rather than phrases such as “next week,” especially if readers may be in another time zone.
Give senders a useful next step: a shared inbox, service desk, or colleague who has agreed to cover your work.
Keep internal and external messages distinct. Colleagues may need more context than customers or other outside contacts.
Before a long absence, check your calendar, shared mailbox coverage, and any forwarding arrangements separately. An automatic reply does not forward, assign, or otherwise manage messages.
For a rule workaround, start with a test message and a temporary rule name that is easy to recognize. Once it works, note where to disable it so it does not keep replying after your return.

Troubleshooting

Automatic Replies is missing: The selected account may be POP or IMAP, or it may be an account managed by an organization that limits the feature. Confirm that the correct mailbox is selected, then try Outlook on the web. If it is a work account and the setting still does not appear, contact your administrator. Use a rule only if you understand that it may depend on Outlook running.

No one receives a reply: Check that the feature is enabled, that the current time falls within the scheduled range, and that the reply is configured for the sender’s audience. Confirm that you saved the settings for the right account. For a rule, verify that it is turned on, that the template path is still available, and that Outlook is open and connected. Test from a different email address because automatic replies may not be sent repeatedly to the same sender during a short period.

The reply starts or stops at the wrong time: Review the start and end values and the displayed time zone. If the mailbox is shared across regions, confirm the schedule with its owner or administrator. Correct the schedule, save it again, and send a new test after the intended start time.

People get two replies, or the rule sends an outdated message: Turn off one of the overlapping methods. Open the rule list and check which template the rule uses; edit the template or select the correct file, then test again. If a rule appears not to run, check whether it is marked as a client-only rule and whether Outlook is online. Organization policies, mail-flow rules, or spam filtering can also affect delivery, so an administrator may need to investigate.

Frequently Asked Questions

Is an out-of-office rule the same as Automatic Replies?
No. Automatic Replies is a built-in feature, usually handled by the mail server for supported Exchange or Microsoft 365 accounts. A rule that replies from a template is a workaround and may depend on desktop Outlook staying open.

Will Outlook send the reply if my computer is off?
Server-based Automatic Replies for a supported account continue to work while your computer is off. A client-side template rule generally will not process messages while Outlook is closed or disconnected.

Can I send different messages to coworkers and outside contacts?
Yes, the built-in Automatic Replies feature commonly provides separate internal and external message areas. The available options depend on your Outlook version and organization settings. A basic template rule usually sends the same template to messages it matches.

Can I set an automatic reply for a shared mailbox?
Often, but you need permission to access and change that mailbox’s settings, and the exact process depends on how your organization manages it. Select the shared mailbox itself rather than configuring your personal mailbox. Contact your administrator if its Automatic Replies option is unavailable.

Why does the same person not get a reply every time?
Automatic reply systems commonly limit repeated responses to the same sender to prevent loops and excessive messages. A test from an address that has already received a reply may therefore be misleading. Test with a different address or check the setting after the system’s reply interval.

How do I stop the replies when I return?
If you set a time period, confirm its end time is correct; the feature should stop at that time. Otherwise, reopen Automatic Replies and turn it off. For a rule, go to the rules list and clear its enabled checkbox or remove it, then verify that no other reply method remains active.
