Setting an out of office reply in Outlook is a small task that prevents missed expectations, repeated follow ups, and confusion while you are unavailable. Whether you use Outlook on Windows, Mac, the web, iPhone, or Android, the process is straightforward once you know where Microsoft places the automatic reply settings in each version.
TLDR: In most versions of Outlook, open Settings or File, find Automatic Replies, turn the feature on, choose a date range, and write a clear message. For example, if you are away from March 4 to March 8, your reply might say: “I am out of the office until March 11 and will respond when I return.” A practical workplace survey scenario: if 40 clients email you during a five day absence, even a short automatic reply can reduce unnecessary follow up messages by setting expectations immediately.
Before You Start: Check Your Account Type
Outlook’s automatic reply feature works best with Microsoft 365, Exchange, Outlook.com, and many work or school accounts. If you use a basic POP or IMAP account from some email providers, the built in automatic reply option may not appear. In that case, you may need to use your provider’s webmail settings or create an Outlook rule, though rules usually require Outlook to remain open on your computer.
For business users, it is also worth remembering that your organization may apply policies to automatic replies. Some companies restrict replies to external senders or add security disclaimers. If settings are unavailable, contact your IT administrator before assuming something is broken.
How to Set Up an Out of Office Reply in Outlook for Windows
Outlook for Windows exists in two common versions: classic Outlook and the new Outlook. The steps are different, so use the instructions that match your interface.
Classic Outlook for Windows
- Open Outlook on your Windows computer.
- Select File in the top left corner.
- Choose Automatic Replies. If you do not see this option, your account may not support server based automatic replies.
- Select Send automatic replies.
- Optional but recommended: check Only send during this time range, then set your start and end dates.
- Write your message under Inside My Organization.
- If appropriate, select Outside My Organization and write a version for external contacts.
- Click OK to save.
Use different internal and external messages when necessary. Internally, you may name a colleague who can help. Externally, you may prefer to give a general team inbox instead of sharing direct contact details.
New Outlook for Windows
- Open Outlook.
- Select the Settings gear icon, usually in the upper right corner.
- Go to Accounts, then choose Automatic Replies.
- Turn on Automatic replies.
- Select the account you want to configure if you have more than one mailbox.
- Set a start and end time if you want the reply to turn off automatically.
- Enter your message and choose whether to send replies outside your organization.
- Select Save.
How to Set Up an Out of Office Reply in Outlook on Mac
Outlook for Mac also supports automatic replies for compatible accounts. The setting may appear slightly differently depending on whether you use the new Outlook for Mac interface or an older version.
- Open Outlook on your Mac.
- From the menu bar, select Tools.
- Choose Automatic Replies.
- Select the account you want to update, if prompted.
- Turn on automatic replies.
- Enter your out of office message.
- Set a start and end date so the reply does not continue after you return.
- Choose whether to send replies to people outside your organization.
- Click OK or Save.
If you use multiple mailboxes on Mac, double check the account selected at the top of the automatic replies window. A common mistake is setting an out of office reply for a secondary mailbox while leaving your main account unchanged.

How to Set Up an Out of Office Reply in Outlook on the Web
Outlook on the web is often the easiest place to manage automatic replies, especially for Microsoft 365 work accounts and Outlook.com addresses. Because the setting is saved online, it continues working even when your computer is turned off.
- Go to outlook.office.com or outlook.live.com and sign in.
- Select the Settings gear icon in the upper right corner.
- Choose Mail, then select Automatic replies.
- Turn on Automatic replies.
- Set a time period if you want Outlook to start and stop the reply automatically.
- Write your message in the text box.
- Choose whether to send replies only to contacts or to all external senders, if the option is available.
- Select Save.
For most professional situations, avoid sending detailed internal information to everyone outside your organization. A concise external reply is safer and more polished.
How to Set Up an Out of Office Reply in Outlook Mobile
The Outlook mobile app for iPhone, iPad, and Android includes automatic replies for supported accounts. This is useful when you are already traveling or forgot to enable the message before leaving your desk.
- Open the Outlook app on your mobile device.
- Tap your profile icon or mailbox icon in the upper left corner.
- Tap the Settings gear icon.
- Select the email account you want to update.
- Tap Automatic Replies.
- Turn automatic replies on.
- Choose whether to reply to everyone or only people within your organization.
- Enter your message.
- Set a time range if the app provides the option.
- Tap the check mark, Save, or back button to confirm, depending on your device.
If you manage work email on a personal phone, be careful when composing the message on a small screen. Typographical errors are easier to miss on mobile and can look unprofessional to clients or executives.

What to Include in a Professional Out of Office Message
A good out of office message is brief, accurate, and useful. It should explain your availability without oversharing. In most cases, include the following:
- Your return date: State when you expect to respond.
- Response expectations: Say whether you will have limited access to email or no access.
- An alternate contact: Provide a colleague, shared inbox, or support address for urgent matters.
- A polite closing: Keep the tone professional and calm.
Here is a dependable example:
Thank you for your message. I am out of the office from April 8 through April 12 and will respond after I return on April 15. For urgent matters, please contact the Customer Support team at support@example.com. Thank you for your understanding.
Common Mistakes to Avoid
- Forgetting an end date: This is the most frequent mistake. Always schedule the automatic reply to turn off.
- Sharing too much personal information: You do not need to explain where you are or why you are unavailable.
- Using informal wording: Avoid jokes, vague phrases, or overly casual language in professional accounts.
- Giving the wrong backup contact: Confirm that your colleague or team inbox is prepared to receive urgent requests.
- Sending the same message internally and externally: External senders usually need less detail.
Final Checks Before You Leave
After saving your automatic reply, send yourself a test message from another account if possible. Confirm that the reply is active, correctly worded, and limited to the intended dates. If you are part of a team, notify your manager or backup contact that your message is enabled and that they may receive redirected requests.
Outlook’s out of office feature is simple, but it plays an important role in professional communication. Setting it properly across Windows, Mac, web, or mobile ensures that people receive timely information, your absence is handled smoothly, and your inbox is easier to manage when you return.
