Out of Office in Outlook on Windows 11: Quick Setup

To set an out-of-office reply in Outlook on Windows 11, open Automatic replies for the account you’ll be away from, turn replies on, write your message, and—if available—set a start and end time. The setting belongs to your email account, not to Windows 11, so the steps depend on whether you use the new Outlook or classic Outlook and whether your account supports automatic replies.

Before you leave, send yourself a test message from another account if possible. Check that the dates, message, and recipient options are right. If Outlook does not offer Automatic replies, your email provider may have its own vacation-response setting.

What You’ll Need

Outlook installed and signed in to the account that should send the reply. If you have multiple accounts, identify the correct one before changing settings.
An email account that supports server-based automatic replies, commonly a Microsoft 365 work or school account, an Exchange account, or Outlook.com. Availability can vary for other connected accounts.
Your away dates and a prepared message. You can include a return date and an alternative contact, but avoid sharing private details or information that should not be sent to everyone.

Step-by-Step

Open the Outlook version you use. Windows 11 may have the new Outlook app or classic Outlook for Windows. They have different menus, so use the relevant steps below. To tell them apart, the new Outlook has a modern interface and usually a Settings gear at the upper right; classic Outlook has a File tab on the ribbon.
In new Outlook, open the automatic-reply settings. Select the Settings gear in the upper-right corner, then choose Accounts and Automatic replies. If Outlook asks you to select an account, choose the mailbox that should send the response. The exact labels or layout can vary slightly as Microsoft updates the app. If you cannot find the setting, check that you have selected the right account and continue with the classic Outlook instructions if that is the app you use.
In classic Outlook, open Automatic Replies. Select File on the ribbon, then Automatic Replies. In the dialog, select Send automatic replies. If you see a message saying that automatic replies are unavailable, the account may not support the feature; see Troubleshooting below rather than assuming the reply is active.
Choose whether to schedule the reply. If you know when you will be away, turn on the option to send replies only during a time period, then enter the start and end times. In classic Outlook, this option appears as Only send during this time range. In new Outlook, look for the equivalent date-and-time controls. Check both the date and the time, including AM or PM where shown, and consider the time zone used by the account. A schedule is useful because Outlook can start and stop the replies without you having to remember to switch them off.
Write the reply for people inside your organization. If the settings show separate message areas, enter your internal reply in the box for people in your organization. Keep it clear and brief: say that you are away, when you expect to return, and who can help with urgent work. For example, you could write: I’m away from email until Monday, 18 May. For urgent requests, please contact Jordan Lee at the usual team address. Use a return date that is unambiguous to colleagues in different regions.
Decide whether to reply to people outside your organization. If you want external senders to receive a response, enable the option to send replies outside your organization and enter a separate external message if Outlook provides one. You may be able to limit replies to external contacts or allow replies to anyone outside the organization. Choose the narrower audience if you do not need to notify every sender. External replies can reach customers, vendors, mailing lists, and people you do not know, so do not include internal-only information, confidential project details, or sensitive contact information.
Save or apply the setting. In new Outlook, select Save if the settings pane offers it. In classic Outlook, select OK to close the Automatic Replies dialog and apply your selections. If you chose a scheduled period, the reply may not begin immediately; that is expected if the start time is in the future. Leave Outlook connected to the internet while changing settings so it can save them to the mailbox.
Verify the setup. Reopen the automatic-reply settings and confirm the correct account, active status, schedule, and message. When practical, send a test from an address outside the organization as well as one inside it. Some systems send an automatic reply only once to the same sender during an active period, so a second test from the same address may not produce another reply. If you need to check again, use a different test address or review the setting rather than repeatedly sending messages.
Turn replies off when you return, if they are not scheduled to end. Open the same setting and switch off automatic replies. A correctly saved end time should stop a scheduled reply automatically, but check the status after returning, especially if you changed dates or time zones. If you are extending your absence, update the end time and the wording before the current period expires.

Common Mistakes

Setting the reply on the wrong account. Outlook can contain several mailboxes. A reply configured for your personal account will not necessarily cover your work account. Check the selected account in the settings and verify the address before saving.

Forgetting to set an end time. If you turn replies on without a schedule, they may remain active until you switch them off. That can send an outdated message after you are back. Use a time range when you know your return time, or make a reminder to disable the setting manually.

Assuming an unsent test means the feature is broken. A reply might be scheduled to start later, addressed only to internal or external senders, or limited to one reply per sender. Check those conditions first. Also look in the test mailbox’s junk or spam folder.

Sending too much information to external contacts. An external automatic reply is not a private note. It may go to anyone who emails you, including automated senders. Avoid stating that your home is empty, giving personal travel details, or sharing information that should stay within your organization.

Confusing an automatic reply with a forwarding rule. An out-of-office message tells the sender you are away; it does not automatically forward every message to a colleague. Set up forwarding or delegate access separately if your organization permits it, and check that arrangement with your administrator.

Tips

Use a clear subject-free message when Outlook supplies the reply automatically; the sender will see it as an automatic response. Put the return date near the beginning so it is easy to spot.
Keep the internal and external versions different when necessary. Colleagues may need a team backup contact, while customers may need a shared support address. Make sure any named person has agreed to be listed and is able to help.
Use a specific date rather than phrases such as next week. If you work across time zones, include the relevant time zone when a precise return time matters.
If your organization manages automatic replies through an administrator or mailbox policy, follow its instructions. Policies may restrict external replies or control how long a message remains active.
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 personal one.

Troubleshooting

There is no Automatic Replies option. First confirm which Outlook app and account you are using. Classic Outlook commonly offers the setting for Exchange and Microsoft 365 work or school mailboxes, but it may not appear for an account that does not support server-side replies. For a personal or third-party mailbox, sign in to the provider’s website and look for a vacation responder, out-of-office reply, or automatic response setting. Configure it there so it can reply while Outlook is closed. If this is a work account and you expect the feature to be available, contact your IT administrator.

The reply is not being sent. Reopen the setting and check that replies are on, the selected mailbox is correct, and the current time falls within the scheduled range. Confirm that the right internal or external audience is enabled. Send a new test from a different address, then check the recipient’s junk folder. If your organization uses transport rules or blocks automatic external replies, an administrator may need to investigate.

The wrong message is going out. Check whether there are separate internal and external message boxes and correct each one. Remove stale dates, old phone numbers, or names of people who are no longer covering your work. Save the change, then test with an appropriate address. If a sender already received a reply during the current period, Outlook may not send that same person a revised message automatically; tell them directly if the correction is important.

The reply keeps going after you return. Reopen Automatic replies and turn the feature off, or correct the scheduled end date and time. If the setting appears off but senders still receive a response, check the provider’s web settings and any mailbox rules. A rule created for an automatic response can behave differently from Outlook’s built-in setting, so remove or adjust it only after confirming what it does.

Settings do not save or the menu behaves unexpectedly. Check your internet connection, make sure Outlook is signed in, and try again after restarting the app. In classic Outlook, confirm that you are online rather than working offline. If the problem continues, install available Microsoft 365 updates or ask your organization’s support team to check account permissions and service status.

Frequently Asked Questions

Does Outlook need to stay open for out-of-office replies?
For supported Exchange, Microsoft 365, and Outlook.com mailboxes, the automatic reply is generally handled by the mail service, so Outlook can be closed. A rule-based workaround for an unsupported account may require Outlook to be running and connected; a provider’s own vacation responder is usually the more reliable option.

Can I set different replies for coworkers and external senders?
Yes, when your account and Outlook version show separate internal and external message areas. Enter each message in its corresponding box and enable external replies if you want them sent. Some account types or organization policies may not offer both options.

Will Outlook reply to every message from the same person?
Usually not. Automatic-reply services commonly avoid sending the same person repeated notices during one active period. This helps prevent reply loops and inbox clutter, so do not use your own repeated test emails as the only way to confirm the setting.

Can I set an out-of-office reply in Outlook for Windows without Microsoft 365?
Possibly, depending on the email provider and account type. If the Outlook setting is missing, configure the reply through the provider’s website or app. The fact that Outlook can send and receive messages for an account does not guarantee that it can manage that provider’s automatic replies.

How do I set an out-of-office reply in Outlook on a Mac?
The Mac interface differs from Windows. In Outlook for Mac, open Outlook’s settings and look for Automatic replies under the relevant account, or use the account’s webmail settings if the option is unavailable. The Windows paths in this guide—File > Automatic Replies in classic Outlook and Settings > Accounts > Automatic replies in new Outlook—do not apply exactly to Mac.
