Out of Office in Outlook: Set Your Status and Replies

To set out of office in Outlook, turn on Automatic Replies, enter your message, and—if you know your dates—set a start and end time. Outlook will send the reply to people who email you while it is active. The exact menu depends on whether you use classic Outlook, new Outlook, Outlook on the web, or Outlook for Mac; also note that an automatic reply is not the same as marking calendar time as Out of Office.

What You’ll Need

Access to the Outlook account you want to update. If you have more than one account, confirm which mailbox you are changing.
A short message explaining when you will be away and, if useful, who to contact instead. Prepare a separate version for people outside your organization if needed.
Your departure and return dates, including the time zone if you are working across regions. You can turn replies on without scheduling an end time, but a schedule helps prevent them staying on accidentally.

Step-by-Step

Open the correct mailbox and identify your Outlook version. On Windows, classic Outlook has a File tab in the upper-left corner. New Outlook has a Settings gear and a more web-like layout. You can also use Outlook in a browser or Outlook for Mac. The setting applies to the selected account, so check the account name before proceeding if you have several.
Open Automatic Replies. In classic Outlook for Windows, select File > Automatic Replies. In new Outlook for Windows, select the Settings gear, then Accounts > Automatic replies. In Outlook on the web for a Microsoft 365 work or school account, open Settings > Accounts > Automatic replies; for Outlook.com, look under Settings > Mail > Automatic replies. In Outlook for Mac, look for Tools > Automatic Replies; in some newer layouts, open Settings > Accounts and select the account’s automatic-reply option. Menu labels can vary slightly by release.
Turn on replies and decide whether to schedule them. Select the option to send automatic replies. If you want Outlook to handle the timing, turn on the option labeled something like Send replies only during a time period. Enter the start and end date and time, then check the time zone shown. Replies should begin and stop according to that schedule, even if you are not at your computer. If you do not set a period, remember to return and switch the feature off yourself.
Write the message for people inside your organization. Keep it clear and brief. State that you are away, when you expect to return, and what the sender should do if the matter cannot wait. For example: I’m away from November 10 through November 14 and will reply when I return. For urgent scheduling questions, contact Jordan Lee at the team mailbox. Avoid including sensitive details, personal travel information, or information that should not be shared broadly.
Choose whether to reply to people outside your organization. If Outlook offers a separate external-reply option, decide whether to send a message to all external senders or only people in your contacts. Add an appropriate external message rather than assuming the internal text is suitable for everyone. Some organizations disable external automatic replies or limit who can receive them; if the control is missing or unavailable, your administrator may manage that policy.
Save or apply the settings. Select Save, Done, or the equivalent button if the page presents one. Classic Outlook may show an OK button. Do not just close the settings window if it has an explicit save or apply control. Reopen the settings or look for an on-screen confirmation to make sure the replies are active and the schedule is correct.
Decide whether your calendar also needs an Out of Office entry. Automatic replies tell email senders you are away; they do not, by themselves, reserve your calendar. In Calendar, create an event for the absence, set its availability or Show as value to Out of Office, and make it an all-day event if appropriate. This helps colleagues see that you are unavailable when they check scheduling. Avoid creating a duplicate event if your workplace already adds one through a leave system.
Check the result from a safe test account if practical. Send a brief test from another account, or ask a colleague to confirm what they receive. Automatic replies are commonly sent only once to a sender during an active period, so repeatedly testing from the same address may not generate another message. Confirm the wording, dates, and external audience without sending confidential information.

Common Mistakes

Leaving replies on indefinitely: If you skip the scheduled period, the message may continue after you return. Set an end time when possible, or add a reminder to turn replies off on your first day back.

Assuming an email reply changes your availability: Automatic Replies do not necessarily block meeting invitations or mark your calendar as Out of Office. Add a calendar absence separately when colleagues need to see your availability.

Using only an internal message: External senders may receive no reply if you have not enabled the external option. Conversely, sending a detailed internal message to all external senders can reveal team or contact information. Review both audiences.

Forgetting the selected account or time zone: A shared or secondary mailbox may be selected, or a scheduled reply may start at an unexpected local time. Verify the mailbox and time zone before saving.

Expecting a reply to every email: Outlook limits repeated automatic replies to the same sender, and organization policies can affect delivery. This behavior helps avoid endless reply loops, but it means one test email is not a reliable check of every setting.

Tips

Give a precise return date instead of saying only that you will respond later. If plans are uncertain, use a realistic range or say that you will reply when available.
Provide one dependable alternative contact, with their role or a shared team address. Confirm that the person or team is covering before naming them.
Keep the external message minimal. People outside your organization usually need to know you are unavailable and how to reach an appropriate general contact, not your internal workflow.
For a short absence, a simple reply is enough. For a longer absence, consider whether recurring meetings, delegated approvals, or shared-mailbox coverage need separate arrangements.
If you also use Microsoft Teams, check its presence and status message separately. Outlook automatic replies, calendar availability, and a Teams status message are related in some Microsoft 365 setups, but they are not identical controls and may not update in exactly the same way.

Troubleshooting

You cannot find Automatic Replies. Check that you opened the intended mailbox and are using an account type that supports server-based automatic replies. This feature is available for many Microsoft 365, Exchange, and Outlook.com accounts, but may not appear for some POP or IMAP accounts. Try Outlook on the web for a work or school mailbox. If the feature is still missing, ask your organization’s Microsoft 365 administrator whether it is disabled.

Senders are not receiving the message. Confirm that automatic replies are switched on, that the current time falls within the scheduled period, and that the external-reply option is enabled when relevant. Ask the sender to check junk mail and verify the address they used. Work or school administrators can restrict external replies, so contact IT if internal senders receive a message but external senders do not.

The reply starts or ends at the wrong time. Reopen the setting and inspect the start and end values and time zone. If you set the schedule while traveling or using a device configured to another region, the displayed time may not match what you expected. Correct the schedule and save it again.

The reply is going out after you return. Turn off Automatic Replies immediately or change the end date to the present. Then check whether you enabled replies in another account or Outlook interface as well. If you had no scheduled end, set a reminder next time rather than relying on memory.

Your calendar still shows you as available. That is expected if you enabled only email replies. Add or correct the calendar event and set the availability to Out of Office. If the event does not appear for colleagues, check its sharing permissions and make sure it is on the calendar they can view.

Settings do not seem to stick. Reopen the Automatic Replies page and confirm the saved state. If the page fails to save, refresh Outlook, try another supported Outlook client, and check your network connection. For a managed work account, your administrator may need to resolve a mailbox or policy issue.

Frequently Asked Questions

Is Outlook status the same as an out-of-office reply?
Not exactly. Automatic Replies send an email response. Calendar Out of Office marks you unavailable for scheduling, while Teams has its own presence and status-message controls. Set the relevant ones separately when you need all three.

Can I set an out-of-office reply from Outlook on my phone?
Yes, the Outlook mobile app supports automatic replies for many Microsoft 365, Exchange, and Outlook.com accounts. Open the app’s settings, select the account, and look for Automatic Replies. The exact labels may differ by phone and app version; set a date range if the controls are available.

Will Outlook reply to every message from the same person?
Usually not. Outlook generally sends one automatic reply to a sender during an active period rather than replying to every new message. This prevents repeated replies and mail loops. Do not use repeated test messages from one address to judge whether the feature is working.

Can I have different messages for internal and external senders?
Often, yes. Many Exchange-based Outlook accounts provide separate message areas for people inside and outside your organization. If you do not see the external setting, your account type or administrator’s policy may not support it.

Do I need to leave Outlook open for scheduled replies to work?
For supported Microsoft 365, Exchange, and Outlook.com mailboxes, automatic replies are generally handled by the mail service, so Outlook does not need to remain open. Some other account types or locally configured rules may behave differently; check the account’s available settings or ask your administrator.

How do I stop the replies early?
Open Automatic Replies for the account and switch them off, or edit the scheduled end time to an earlier date and save. If you have more than one mailbox, check each one so you do not leave replies active on a different account.
