Going on vacation? Taking a sick day? Hiding from email while you enjoy a long weekend? Good news. Outlook can do the polite waving for you. An out-of-office reply tells people you are away, when you will return, and who can help while you are gone.
TLDR: In Outlook, look for Automatic Replies or Out of Office. Turn it on, write a short message, and set a start and end time. On mobile, open the Outlook app, go to your account settings, and turn on Automatic Replies. Keep your message clear, friendly, and useful.
What Is an Out-of-Office Reply?
An out-of-office reply is an automatic email response. It is sent when someone emails you while you are away. Think of it as a tiny personal assistant. It says, “Hello! I am not ignoring you. I am just not here.”
You can use it for many reasons:
- Vacation
- Business travel
- Sick leave
- Parental leave
- Holidays
- Focus time or training days
The best out-of-office message is short. It should answer three simple questions:
- When are you away?
- When will you return?
- Who can help instead?
That is it. No need for a dramatic novel about your beach trip. Though tempting.
Before You Start
Outlook comes in a few flavors. There is Outlook for Windows. There is Outlook for Mac. There is also Outlook on iPhone and Android. The buttons may look a little different. But the idea is the same.
You are looking for a setting called Automatic Replies. Sometimes people call it Out of Office, or just OOO. It all means the same thing.
Also, automatic replies usually work best with Microsoft 365, Exchange, or Outlook.com accounts. If you use a POP or IMAP account, you may not see the same option. In that case, you may need to create a rule instead. But for most work and school Outlook accounts, the normal method works.
How to Set an Out-of-Office Reply in Outlook for Windows
If you use Outlook on a Windows desktop, follow these steps. They are quick. No wizard hat needed.
- Open Outlook on your computer.
- Click File in the top left corner.
- Select Automatic Replies.
- Choose Send automatic replies.
- Check Only send during this time range, if you want it to start and stop by itself.
- Choose your start time and end time.
- Type your message in the box.
- Click OK.
Outlook may give you two tabs. One is for people inside your organization. The other is for people outside your organization. This is handy.
For coworkers, you can include more details. For outside contacts, keep it simple. You may not want to share too much. Your email does not need to announce, “My house is empty and my plants are in charge.”
How to Set an Out-of-Office Reply in the New Outlook for Windows
The new Outlook looks more like Outlook on the web. It has cleaner menus. It also hides things in places that feel like a tiny treasure hunt.
- Open the new Outlook.
- Click the gear icon in the top right corner.
- Select Accounts.
- Choose Automatic Replies.
- Pick the account you want to update.
- Turn on Automatic replies.
- Set your date and time range.
- Write your message.
- Click Save.
You may also see options to block your calendar, decline new events, or send replies only to contacts. These are useful. If you are truly away, blocking your calendar is a smart move. It stops meetings from sneaking in like little calendar goblins.
How to Set an Out-of-Office Reply in Outlook for Mac
Using a Mac? No problem. Outlook still has your back.
- Open Outlook on your Mac.
- Click Tools in the menu bar.
- Select Automatic Replies.
- Choose the account you want to use.
- Turn on automatic replies.
- Set your start and end dates.
- Type your reply message.
- Click OK or Save.
As with Windows, you may be able to create separate replies. One reply can go to people inside your company. Another can go to outside contacts. This helps you sound friendly without oversharing.
How to Set an Out-of-Office Reply in Outlook Mobile
Now let us talk about your phone. Maybe you are already at the airport. Maybe you forgot to set your out-of-office before leaving. Maybe your suitcase is packed, but your inbox is not. Outlook mobile can save the day.
These steps work for both iPhone and Android. The layout may vary a little, but the path is very similar.
- Open the Outlook app on your phone.
- Tap your profile icon or menu icon in the top left.
- Tap the gear icon for settings.
- Select your email account.
- Tap Automatic Replies.
- Turn automatic replies on.
- Choose whether to reply to everyone or only your organization.
- Set your time range, if available.
- Write your message.
- Tap the check mark or Save.
That is it. You can now return to your coffee, your train, your couch, or your tropical pineapple drink.
What Should Your Message Say?
A good out-of-office reply is not fancy. It is helpful. It should be warm, direct, and easy to read.
Here is a simple example:
Hello,
Thank you for your email. I am out of the office from Monday, July 8, through Friday, July 12. I will reply when I return on Monday, July 15.
If you need urgent help, please contact Jamie Lee at jamie@example.com.
Best,
Alex
Nice, right? It says everything. No fluff. No confusion. No mysterious “I am currently unavailable” with no return date. That kind of message makes people stare into the void.
Tips for a Great Out-of-Office Reply
Use these quick tips to make your message shine:
- Give dates. Say when you leave and when you return.
- Name a backup person. Include their email if possible.
- Be clear about urgency. Tell people what to do if it matters now.
- Keep it short. People do not need your full travel schedule.
- Use a friendly tone. You can be professional and human.
- Do not share private details. Safety first. Mystery is fine.
If you are away for a holiday, you can add a cheerful line. For example, “Wishing you a wonderful holiday season.” If you are away for personal reasons, keep it plain. You do not owe anyone a full explanation.
Internal vs. External Replies
Outlook may let you create two messages. This is one of its best little tricks.
Internal replies go to people inside your company or school. You can include more detail here. You might mention project status, team contacts, or where files are saved.
External replies go to clients, vendors, or anyone outside your organization. Keep these more general. Include only what they need to know.
For example, your internal reply might say:
I am away this week. For the budget file, check the shared Finance folder. For approvals, contact Priya.
Your external reply might say:
Thank you for your message. I am out of the office until Monday. For urgent support, please contact support@example.com.
See the difference? Same idea. Different level of detail.
How to Turn It Off
If you set an end time, Outlook should turn off the reply by itself. Lovely. Technology did a tiny helpful thing.
If you did not set an end time, you must turn it off manually. Go back to Automatic Replies and choose Do not send automatic replies. On mobile, return to the same setting and switch it off.
Do this as soon as you return. Otherwise, people may think you are still away while you are sitting right there, answering emails like a champion.
Common Problems
If automatic replies are not working, try these checks:
- Make sure you selected the correct email account.
- Check that automatic replies are turned on.
- Confirm the start and end times are correct.
- Make sure your account supports automatic replies.
- Restart Outlook if the setting looks stuck.
- Ask your IT team if your company has special rules.
Also remember this. Outlook usually sends one automatic reply per sender during a set period. So your coworker may not get the same reply every time they email you. That is normal. Outlook is being polite, not broken.
Final Thought
Setting an out-of-office reply in Outlook is simple once you know where to click. On desktop, go to Automatic Replies. On mobile, open your account settings and turn it on there. Add your dates, write a clear message, and name someone who can help.
Then step away from the inbox. Your automatic reply is on duty. Tiny robot email butler activated.
