An Owa out of office away message is an automatic reply you set in Outlook on the Web (OWA) that tells people you are away and when you will respond. You set it under Settings > Mail > Automatic replies, and you can send it to people inside your organization only, or to everyone who emails you. This guide explains the exact steps, the difference between internal and external replies, and how to schedule the message so it turns on and off by itself.
What Is OWA and Why Use It for Away Messages?
Outlook on the Web (OWA) is the browser-based version of Microsoft Outlook that comes with Microsoft 365 and Exchange Online mailboxes. It runs in any modern browser, so you can set an away message from a shared computer, a friend’s laptop, or your phone without installing the desktop app. The automatic reply feature in OWA is the same one that the desktop Outlook uses, and it syncs with your Exchange mailbox, so the message you set in OWA will also appear when you use Outlook on your phone or desktop.
An away message (also called an automatic reply or out-of-office reply) is useful for vacations, business trips, medical leave, or any time you cannot check email for more than a few hours. It sets expectations for the sender, reduces follow-up emails, and protects you from feeling pressured to reply while you are off.
How to Set an Automatic Reply in OWA (Step by Step)
The exact menu names can vary slightly depending on your organization’s Microsoft 365 version, but the general path is the same.
- Sign in to Outlook on the Web (outlook.office.com or your company’s OWA link).
- Click the gear icon (Settings) in the top-right corner.
- At the bottom of the Settings pane, click View all Outlook settings.
- In the Settings window, choose Mail > Automatic replies.
- Toggle on Turn on automatic replies.
- Optionally, check Send replies only during a time period and set a start and end date and time.
- In the Inside my organization box, type the message your coworkers will see (for example, “I’m out of the office from June 3–7 and will reply when I return.”).
- If you want people outside your company to get a reply, check Send replies outside my organization and type a separate message in the Outside my organization box. You can choose Anyone outside my organization or Only contacts.
- Click Save at the top of the Settings window.
Once saved, the toggle shows as on, and a banner appears at the top of your mailbox indicating that automatic replies are on. To turn them off early, follow the same steps and toggle off the switch.
Internal vs. External Replies: What’s the Difference?
OWA lets you write two different messages: one for people inside your organization and one for external senders. This is useful because your internal message can be casual and mention project details, while your external message might be more formal and include a colleague’s contact information for urgent matters.
By default, external replies are off. If you turn on the external option, you can choose to send replies to Anyone outside my organization or only to Contacts. Sending to everyone is common for public-facing roles like sales or support, but it can also cause email loops if two auto-responders are talking to each other. Microsoft’s Exchange server has protections against loops, but it’s still a good idea to avoid replying to newsletters or automated messages by only replying to contacts if you are concerned.
Note that external replies are only sent once per sender per day, so a person who emails you multiple times will only get one automatic response.
Scheduling the Away Message to Turn On and Off Automatically
You don’t have to remember to turn off the reply when you return. The Send replies only during a time period option lets you set a start and end date and time. For example, if you leave on Friday, March 14 at 5:00 PM and return on Monday, March 24 at 8:00 AM, you can schedule the reply to start at 5:00 PM on the 14th and end at 8:00 AM on the 24th.
Important: the time period uses your local time zone as set in OWA. If you travel to a different time zone, the reply will still follow your home time zone unless you change it in OWA settings. To avoid confusion, set the end time to the moment you plan to start working again, not the moment you land. If you are unsure of your return time, it’s safer to set a slightly later end time and turn it off manually when you’re back.
Common Problems and How to Fix Them
- Automatic reply not sending: Check that the toggle is on, and that you didn’t accidentally set a time period that has already passed. Also, if you have a rule that deletes or forwards incoming mail, it can interfere.
- External replies not going out: Make sure you checked the box and selected either “Anyone outside my organization” or “Only contacts.” If you chose “Only contacts,” the recipient must be in your Contacts folder, not just someone you’ve emailed.
- Reply sent to internal people but not external: This is normal if you didn’t enable the external option. Enable it if you want external senders to receive a reply.
- Can’t find the Automatic replies setting: Some organizations disable this feature for security or compliance reasons. Contact your IT helpdesk if the toggle is missing.
- Duplicate replies from desktop Outlook: Since OWA and desktop Outlook share the same mailbox, setting the reply in one place should sync to the other. If you see duplicates, restart Outlook or sign out and back in.
Best Practices for Writing an Effective Away Message
Keep your message short and clear. State that you are out of the office, the dates you are away, and when you will reply. If you want, add an alternative contact for urgent matters, but only if that person has agreed to handle your email.
- Include the exact return date: “I will be out from May 20–24 and will respond to your email after I return on May 27.”
- For internal messages, you can be more casual: “I’m on vacation next week, back on Monday. For urgent issues, contact Priya.”
- For external messages, avoid internal jargon and include your full name and title if needed.
- Do not include sensitive information like your home address or personal phone number.
- If you are on a long leave, consider setting a reply that says “I will have limited access to email” rather than “I will not check email at all.”
Frequently Asked Questions
Will my OWA away message also work in the Outlook desktop app?
Yes, the automatic reply is stored on the Exchange server, so it applies to all clients that connect to your mailbox, including Outlook desktop, Outlook mobile, and OWA. If you set it in one place, it will be active in the others.
Can I set different messages for different senders (e.g., my boss vs. a client)?
OWA only gives you two categories: inside your organization and outside. You cannot create separate messages for individual people. For more granular control, you would need to use Outlook rules or a third-party tool, but that’s beyond OWA’s built-in features.
How often will someone receive my automatic reply?
Exchange sends an automatic reply to each sender only once per day (per sender, not per email). So if someone emails you three times in one day, they’ll get only one reply. This prevents mail loops and spam.
What happens if I forget to turn off the automatic reply?
If you scheduled a time period, it will turn off automatically at the end time. If you didn’t schedule it, it will stay on until you manually turn it off. That’s why it’s a good habit to always set an end time.
Can I use OWA to set an away message for a shared mailbox?
Yes, if you have full access permission to a shared mailbox, you can open it in OWA (by right-clicking the mailbox and choosing “Open shared mailbox”) and then set automatic replies for that mailbox. The steps are the same, but you must be signed in as a user with permission.
Does the away message work if I’m on vacation and my internet is down?
Yes, because the reply is sent by the Exchange server, not by your device. As long as your mailbox is online, the server will send the reply even if you are offline.
Alternatives to OWA’s Built-in Away Message
If you need more advanced features, such as different messages for different senders or a rule that forwards urgent emails to a colleague, you can use Outlook rules. In OWA, go to Settings > Mail > Rules, and create a rule that forwards email from certain people to another address, or that replies with a specific message. However, the built-in automatic reply is the simplest and most reliable for most people.
For Microsoft Teams, you can also set a status message that says “Away” or “Out of office,” but that only affects Teams chats, not email. If you want a unified out-of-office experience, set both your email automatic reply and your Teams status message.
