How to Set Out of Office in Outlook: A Step-by-Step Guide

If you have ever returned from vacation to find colleagues wondering why you never replied, you already know why setting up an out of office reply matters. Outlook's automatic replies feature lets you notify anyone who emails you that you are away and when they can expect a response, saving everyone time and frustration.

This guide walks you through exactly how to set out of office in Outlook across every version you might be using, including the new Outlook for Windows, classic Outlook, Outlook on the web, and the Outlook mobile app. You will also learn best practices for writing effective out of office messages and how to troubleshoot common issues.

How Out of Office Automatic Replies Work in Outlook

Outlook's out of office feature, officially called Automatic Replies, sends a pre-written response to anyone who emails you while the feature is active. The system sends your reply once to each sender, so the same person will not receive your auto-reply multiple times if they send you several messages [1].

There are a few important things to understand before setting it up. Automatic Replies require a Microsoft Exchange or Microsoft 365 email account. If your organization uses Microsoft 365 Business, Enterprise, or Education plans, you have access to this feature. Personal accounts using POP or IMAP protocols (such as Gmail or Yahoo connected to Outlook) do not support automatic replies through the built-in feature [1].

You can configure two separate messages: one for people inside your organization and another for external senders. This distinction is useful because you might share more detail with colleagues (such as who is covering your responsibilities) while keeping the external message brief and professional.

Requirements for setting up automatic replies

• A Microsoft 365 or Exchange email account
• Access to Outlook (desktop app, new Outlook, web, or mobile)
• Your organization's Exchange server must support the Automatic Replies feature
• Administrator permissions are not required for individual users to set their own out of office replies

How to Set Out of Office in the New Outlook for Windows

The new Outlook for Windows has a streamlined settings interface that makes configuring automatic replies straightforward. Follow these steps to set up your out of office message [1]:

1. Open Settings by selecting the gear icon in the top-right corner of the Outlook window, or navigate to the View tab and select View Settings.
2. Navigate to Automatic Replies by selecting Accounts in the left sidebar, then clicking Automatic Replies.
3. Enable automatic replies by toggling the Turn on automatic replies switch to the on position.
4. Set a time range by selecting Send replies only during a time period and entering your start and end dates and times. This ensures your replies turn off automatically when you return.
5. Write your internal message in the text box under Send automatic replies inside your organization. Use the formatting toolbar to adjust fonts, colours, and emphasis.
6. Configure external replies by selecting Send replies outside your organization and writing a separate message for people outside your company. Choose whether to send to all external senders or only to your contacts.
7. Save your settings by clicking Save at the top of the window.

How to Set Out of Office in Classic Outlook (Desktop)

If you are using the classic version of Outlook for Windows (Outlook 2016, 2019, 2021, or the classic Microsoft 365 version), the process uses the File menu [1]:

1. Open the File tab by clicking File in the top-left corner of the Outlook ribbon.
2. Select Automatic Replies from the Account Information screen. You will see a button labelled Automatic Replies (Out of Office).
3. Choose Send automatic replies in the dialog box that appears.
4. Set the time range by checking Only send during this time range and selecting your start and end dates and times. If you skip this step, you will need to turn off automatic replies manually when you return.
5. Write your internal message on the Inside My Organization tab. This message goes to colleagues and other people within your Exchange organization.
6. Write your external message by switching to the Outside My Organization tab. Check the box to enable external replies, then compose your message. Select whether to send replies to My contacts only or to Anyone outside my organization.
7. Click OK to activate your automatic replies.

What if you do not see the Automatic Replies button

If the Automatic Replies option does not appear after clicking File, your email account is likely a POP or IMAP account rather than an Exchange or Microsoft 365 account. In this case, you can use Outlook's Rules and Alerts feature to create a basic auto-reply rule instead [1]. However, rules-based auto-replies have limitations: they only work while Outlook is running on your computer, and they lack the scheduling and internal/external message separation that Automatic Replies provides.

How to Set Out of Office in Outlook on the Web

Outlook on the web (accessed through outlook.office.com or your organization's webmail portal) provides a clean interface for managing automatic replies [2]:

1. Open Settings by clicking the gear icon in the top-right corner of the page.
2. Navigate to Automatic Replies by selecting Accounts, then Automatic replies.
3. Turn on automatic replies using the toggle switch.
4. Set a time period by selecting the Send replies only during a time period checkbox and entering your start and end dates.
5. Choose calendar options if desired. Outlook on the web offers additional options that the desktop app does not, including the ability to block your calendar for the period, automatically decline new meeting invitations, and decline and cancel existing meetings during your absence.
6. Write your message in the text box at the bottom of the window. Use the formatting toolbar to style your text.
7. Enable external replies by selecting Send replies outside your organization and composing a separate message for external senders.
8. Click Save at the top of the window.

To turn off automatic replies manually, return to the same settings page and toggle the Automatic replies on switch to the off position.

How to Set Out of Office on the Outlook Mobile App

You can also manage your automatic replies from the Outlook app on iOS or Android, which is convenient when your plans change while you are already away from your desk:

1. Open the Outlook app on your phone or tablet.
2. Tap your profile icon in the top-left corner, then tap the Settings gear icon.
3. Select your account from the list of email accounts.
4. Tap Automatic Replies to open the configuration screen.
5. Toggle automatic replies on and configure your message and time range.
6. Save your settings by tapping the checkmark or Save button.

Tips for Writing an Effective Out of Office Message

Setting up the automatic reply is only half the job. The content of your message matters just as much as enabling the feature. A well-written out of office message sets clear expectations and helps people get the assistance they need while you are away.

Include the essentials in every out of office message:

• The dates you will be unavailable
• When the sender can expect a response from you
• An alternative contact person with their name and email address
• A brief, professional tone

Sample internal message:

Thank you for your email. I am out of the office from March 10 to March 14 with limited access to email. For urgent matters, please contact Jane Smith at jane.smith@company.com. I will respond to all messages when I return on March 17.

Sample external message:

Thank you for reaching out. I am currently out of the office and will return on March 17, 2026. For immediate assistance, please contact our team at support@company.com. I will respond to your message as soon as possible upon my return.

Troubleshooting Common Out of Office Issues

Automatic Replies option is missing

If you cannot find the Automatic Replies option in Outlook, the most likely cause is that your email account is not connected to Microsoft Exchange or Microsoft 365. POP and IMAP accounts (including Gmail, Yahoo, and personal Outlook.com accounts connected via IMAP) do not support this feature. Check with your IT administrator to confirm your account type [1].

Out of office replies are not being sent

Several factors can prevent automatic replies from working correctly. First, verify that the feature is actually turned on by checking your settings. If you set a time range, confirm that the current date and time fall within that range. Also ensure that your mailbox has not exceeded its storage quota, as a full mailbox can prevent automatic replies from being sent.

Replies are being sent to every email including spam

By default, if you enable external replies, Outlook sends your auto-reply to every incoming message, including newsletters and junk mail. To limit this, select the Send replies only to contacts option (in new Outlook and Outlook on the web) or My contacts only (in classic Outlook). This ensures your out of office message only goes to people in your address book [2].

Out of office did not turn off automatically

If your automatic replies remain active after your scheduled end date, check that the time zone settings in your Outlook account are correct. A mismatch between your local time zone and the time zone configured in Exchange can cause the schedule to behave unexpectedly. You can always turn off automatic replies manually through the same settings menu.

Common Questions About Setting Out of Office in Outlook

Can you set out of office in Outlook without an Exchange account?

The built-in Automatic Replies feature requires a Microsoft 365 or Exchange account. If you have a POP or IMAP account, you can create a basic auto-reply using Outlook's Rules and Alerts feature, but it only works while Outlook is open and running on your computer. For a reliable out of office experience, a Microsoft 365 account is recommended.

Does the out of office reply send to every email you receive?

No. Outlook sends your automatic reply once to each unique sender. If the same person emails you three times while you are away, they will only receive your out of office message after their first email. This prevents your contacts from being flooded with repeated auto-replies [1].

Can you set different out of office messages for different people?

Outlook allows you to create two separate messages: one for people inside your organization and one for external senders. You cannot create individual messages for specific people, but the internal/external split covers the most common need. Your internal message can include more detail about coverage and responsibilities, while the external message stays brief and professional.

How far in advance can you schedule an out of office reply?

You can schedule your automatic replies as far in advance as you like. Simply set the start date and time to whenever your absence begins. This is useful for planning vacation auto-replies days or weeks ahead of time, so you do not forget to enable them before you leave.

Do out of office replies work on holidays and weekends?

Yes. Once enabled, automatic replies are active 24 hours a day, 7 days a week, including holidays and weekends. They continue until the scheduled end date or until you manually turn them off. The feature runs on the Exchange server, so it works regardless of whether your computer or phone is turned on.

Best Practices for Managing Out of Office in Your Organization

If you are an IT administrator managing Microsoft 365 for your organization, there are additional considerations for how out of office replies work across your environment.

Administrators can configure out of office replies on behalf of users through the Exchange Admin Center or PowerShell. This is useful when an employee leaves unexpectedly or when you need to set up auto-replies for shared mailboxes. The Exchange Online PowerShell command Set-MailboxAutoReplyConfiguration provides full control over automatic reply settings for any mailbox in your tenant.

Consider establishing organizational guidelines for out of office messages to maintain a consistent, professional image. Standard templates that include the company name, alternative contacts, and expected response times help ensure that every auto-reply reflects well on your business.

For companies using shared mailboxes in Microsoft 365, automatic replies can also be configured to notify senders when the shared mailbox is unmonitored during holidays or office closures.

Take Control of Your Microsoft 365 Environment

Managing Microsoft 365 for your business takes time, expertise, and constant attention. If your team is spending hours on IT administration instead of focusing on your core business, it might be time to bring in a partner. Always Beyond provides fully managed Microsoft 365 services for growing businesses across Calgary and beyond, from user management and security configuration to ongoing support and strategic guidance.
