How to Create an Out of Office Message on Outlook

Setting up an out of office message in Outlook sounds simple — and it usually is — but the exact steps depend on which version of Outlook you're using, how your email account is set up, and whether your organization runs Microsoft Exchange. Getting it wrong means either your auto-reply never fires, or it goes out to people it shouldn't. Here's a clear breakdown of how it actually works.

What an Out of Office Message Actually Does

An out of office message (also called an automatic reply) is an auto-response that Outlook sends on your behalf while you're away. When someone emails you, they receive your pre-written message automatically — without you lifting a finger.

Outlook handles this in two ways depending on your setup:

  • Server-side replies — If you're on a Microsoft Exchange, Microsoft 365, or Outlook.com account, the mail server itself sends the reply. This means auto-replies go out even when your computer is off or Outlook is closed.
  • Client-side rules — If you're using a POP3 or IMAP account (common with personal email providers like Gmail via Outlook), the reply only sends while Outlook is open and running on your device.

That distinction matters more than most people realize. Many users set up an out of office message, close their laptop, and assume it's running — only to find out it was never sent.

How to Set Up Automatic Replies in Outlook (Exchange / Microsoft 365) 📧

This is the most common setup for work accounts.

  1. Open Outlook and click File in the top-left corner.
  2. Select Automatic Replies (Out of Office).
  3. Choose Send automatic replies.
  4. Optionally, check Only send during this time range and set your start and end dates — Outlook will turn the auto-reply on and off automatically.
  5. Type your message in the Inside My Organization tab (for colleagues).
  6. Click the Outside My Organization tab to write a separate message for external contacts, or check the box to send the same reply to everyone.
  7. Click OK.

The message goes live immediately (or at your scheduled start time) and runs on the server — no need to keep Outlook open.

If You Don't See "Automatic Replies" in the File Menu

If the Automatic Replies option is missing, your account is likely POP3 or IMAP rather than Exchange. In that case, you'll need to create the auto-reply using rules combined with a template.

Here's the general process:

  1. Create a message template: Write a new email, go to File → Save As, and choose Outlook Template (.oft) as the file type.
  2. Set up a rule: Go to File → Manage Rules & Alerts → New Rule.
  3. Choose Apply rule on messages I receive, then set the condition to apply to all messages (or specific senders).
  4. Set the action to reply using a specific template, and point it to the .oft file you saved.
  5. Enable the rule.

The critical limitation here: Outlook must be open and running for this rule to fire. If you close the app, emails arrive silently with no reply sent.

Setting Up Out of Office in Outlook on the Web (OWA)

If you access Outlook through a browser — common in many corporate environments — the steps are slightly different:

  1. Click the gear icon (Settings) in the top-right corner.
  2. Search for "automatic replies" in the settings search bar, or navigate to Mail → Automatic replies.
  3. Toggle Automatic replies to on.
  4. Optionally set a time range.
  5. Write your message for internal and external senders separately.
  6. Save.

Web-based Outlook also runs server-side, so the reply will send regardless of whether you're logged in.

Setting Up Out of Office on Outlook Mobile

The Outlook mobile app (iOS and Android) also supports automatic replies for Exchange and Microsoft 365 accounts:

  1. Tap the hamburger menu (three lines) in the top-left.
  2. Tap the gear icon to open Settings.
  3. Select your email account.
  4. Tap Automatic Replies.
  5. Toggle it on, set your time range and message, then save.

Note that not all account types will show this option in mobile. If you're using a non-Exchange account through the Outlook app, you may not see automatic replies as an available setting.

The Variables That Change Your Experience

Several factors determine which method applies to you and how reliably it works:

VariableWhy It Matters
Account typeExchange/Microsoft 365 = server-side. POP3/IMAP = client-side rules only.
Outlook versionOlder versions (2010, 2013) have slightly different menu paths than 2019 or 365.
PlatformDesktop, web, and mobile each have separate setup flows.
Organization settingsIT administrators can restrict or modify auto-reply behavior for external senders.
Time zone settingsScheduled replies depend on your account's time zone, not your device's local time.

What to Include in an Effective Out of Office Message 💼

The technical setup matters, but the message content matters just as much. A well-written out of office reply typically includes:

  • Return date — so the sender knows when to expect a response
  • Reason for absence (optional) — vacation, travel, or leave; keep it brief
  • Alternative contact — a colleague or team inbox for urgent matters
  • Response timeframe — when you'll realistically reply after returning

What to avoid: overly long messages, sharing unnecessary personal details, or promising specific response times you can't guarantee.

Internal vs. External Reply Customization

Outlook's Exchange integration lets you write two separate messages — one for people inside your organization and one for external senders. This is worth using deliberately.

Your internal message might include your mobile number or details about project handoffs. Your external message should typically be more generic — just your return date and an alternate contact. Sending internal details to clients or unknown senders is a common mistake that's easy to avoid by using these two fields intentionally.

Where Your Setup Leaves Things Open

The mechanics of Outlook's out of office feature are consistent, but what the right setup looks like for you depends on factors only you can see: whether your account runs through Exchange, which version of Outlook your organization uses, whether your IT team has placed restrictions on external auto-replies, and even whether you need different messages for different groups of senders. The steps above cover the standard paths — but your specific environment may behave differently than the defaults suggest.
