What Is the Out of Office Feature in Outlook?
An Out of Office message in Outlook is an automatic reply sent to people who email during a set time away.

Outlook allows users to choose start and end times, write custom messages, and set different replies for internal and external senders.
This ensures coworkers get detailed updates while outside contacts receive a brief notice.
When used correctly, the message reduces follow-up emails and avoids confusion. It also shows respect for others’ time by setting clear expectations.
Outlook supports this feature across desktop, web, and mobile versions, making it easy to manage availability.

Setting up Out of Office in Outlook Office 365

Set up an Out of Office in Outlook Office 365 to automatically notify senders of your absence with customized messages during your time away from work.
Step 1: Open Automatic Replies in Outlook Office 365
To begin, Outlook Office 365 users must access the Automatic Replies option from account settings. This is done by opening Outlook, selecting the File tab, and choosing Automatic Replies from the menu.
Once opened, users can enable automatic replies with a single click. This feature is connected to the email account, meaning replies will be sent even when Outlook is closed.
The Automatic Replies window also displays key options such as scheduling, message editing, and reply rules. Reviewing these options carefully helps prevent setup errors.
Step 2: Set the Date and Time Range
After enabling Automatic Replies, setting a specific start and end time ensures replies are sent only during the intended absence.
In Outlook Office 365, users can set exact dates and times, which helps prevent replies from being sent too early or remaining active too long.
When the time range is enabled, Outlook automatically turns replies on and off without manual action. Users should double-check time zones, particularly when traveling, to ensure accuracy.
Step 3: Write Internal and External Messages
Outlook Office 365 allows separate Out of Office messages for internal coworkers and external contacts.
Each message is written in its own text box within the Automatic Replies window. Formatting tools are available to adjust spacing or add clarity.
It is recommended to avoid sharing sensitive information in external replies. Users can also choose to send external replies only to contacts or to all senders.
Step 4: Test and Confirm Settings
Once messages and schedules are set, saving the changes activates Automatic Replies immediately or at the scheduled time.
Outlook Office 365 confirms activation before closing the settings window. Testing the setup by sending a message from another account can help verify that replies work as expected.
This step helps catch issues like missing dates or empty message fields. Users should also check calendar settings if blocking time away is required.
Common Out of Office Issues in Outlook
These tips address frequent Outlook issues and help ensure automatic replies work correctly across all versions reliably.
- Check date and time range: Automatic replies may not send if start or end times are incorrect, disabled, or set in the wrong time zone.
- Verify correct account selection: Outlook profiles with multiple accounts can apply replies to the wrong mailbox, leaving the intended inbox without any automatic response.
- Enable external replies properly: If external messages are not checked or limited to contacts only, senders outside the organization will never receive notifications.
- Keep Outlook and server synced: Cached mode, offline status, or server delays can prevent replies from sending even when Automatic Replies appear enabled.
- Test before leaving: Sending a test email from another account confirms activation, message content, and timing, reducing the chance of unnoticed setup mistakes.
