You need to set an automatic reply while you are away, but you want to send one message to colleagues and a different one to people outside your organization. Outlook’s standard automatic reply feature sends the same message to everyone. This article explains how to use the Rules Wizard to create two separate out-of-office responses based on the sender’s address.
Key Takeaways: Setting Separate Auto-Replies
- Rules Wizard: Creates a rule that checks the sender’s domain and sends a specific reply only during your set out-of-office period.
- Internal/External Condition: Use the “with specific words in the sender’s address” condition to filter emails from your company’s domain versus all other domains.
- Two Separate Rules: You must create one rule for internal senders and a second, broader rule for everyone else to avoid sending duplicate replies.
How Separate Auto-Replies Work in Outlook
Outlook for Microsoft 365 and Outlook connected to Microsoft Exchange Server have a built-in automatic reply feature found under File > Automatic Replies. This tool sends one universal message. To send targeted replies, you must use the Rules Wizard. This method works by creating mail flow rules that activate only when your automatic replies are turned on. The rules check incoming messages and reply with a specific template you design. You need an Exchange account for this method to function, as it relies on server-side rules.
Steps to Create Separate Internal and External Auto-Replies
First, write the two different reply messages in separate text files or draft emails. Know your organization’s email domain, such as @contoso.com. Then, turn on the standard automatic replies with a generic message, as this enables the rule conditions for out-of-office periods.
- Open the Rules Wizard
Go to File > Manage Rules & Alerts. Click New Rule on the E-mail Rules tab. - Start from a blank rule
In the Rules Wizard, select “Apply rule on messages I receive” and click Next. - Set the condition for internal senders
Check the box for “with specific words in the sender’s address”. In the lower pane, click the “specific words” link. Enter your company’s domain, like @contoso.com. Click Add, then OK. Click Next. - Choose the reply action
Check the box for “reply using a specific template”. In the lower pane, click the “a specific template” link. In the dialog that opens, select User Templates in File System. Browse to and select your pre-saved template for internal replies. Click Open, then OK. Click Next. - Add any exceptions and name the rule
You can add exceptions if needed, such as excluding messages marked as High Importance. Click Next. Name the rule “Internal OOO Reply”. Check the box for “Turn on this rule”. Also, check the box for “Run this rule when I’m out of the office”. This is the critical setting. Click Finish. - Create the external sender rule
Repeat steps 1 and 2 to create a new rule. For the condition, check “sent to people or public group”. In the lower pane, click the “people or public group” link. Select your own email address from the address book and add it. This rule will apply to all messages sent to you. Click Next. - Set the action and critical exception
Check the box for “reply using a specific template” and link your external reply template. Click Next. Now, you must add a crucial exception. Check the box for “except if the sender’s address contains specific words”. Click the “specific words” link and enter your internal domain, like @contoso.com. This prevents the external rule from firing for internal emails. Click Next. - Name and activate the external rule
Name this rule “External OOO Reply”. Ensure “Turn on this rule” and “Run this rule when I’m out of the office” are both checked. Click Finish. - Enable Automatic Replies
Go to File > Automatic Replies. Select “Send automatic replies”. Set your time range. The message here can be generic or blank, as your rules will send the specific replies. Click OK.
Common Mistakes and Limitations to Avoid
Both rules send replies to internal senders
This happens if the external rule does not have the proper exception. The external rule condition is “sent to me”, which includes everyone. You must add the exception “except if the sender’s address contains [your domain]” to block it from replying to internal contacts.
Rules do not send any replies
First, verify that standard automatic replies are turned on in File > Automatic Replies. The “Run this rule when I’m out of the office” option only works when that main switch is active. Also, ensure your rules are enabled in the Manage Rules & Alerts dialog.
Replies are sent to mailing lists or newsletters
Your rules will reply to any incoming email, including automated system messages. To prevent this, edit each rule and add an exception. In the Rules Wizard, on the exceptions step, add “except if the subject contains specific words” and enter common newsletter subjects or the name of internal distribution lists.
Rule-Based vs. Standard Automatic Replies
| Item | Rules Wizard Method | Standard Automatic Replies |
|---|---|---|
| Customization | Can send different messages based on sender domain or group | Sends one identical reply to all senders |
| Setup Complexity | Requires creating and testing multiple mail flow rules | Simple one-dialog setup with date picker |
| Control Over Recipients | Can add exceptions for newsletters, specific people, or domains | Only offers one “My Contacts only” filter for external replies |
| Template Formatting | Uses Outlook template files for rich HTML formatting | Uses a basic text editor within the Automatic Replies dialog |
| Account Requirement | Requires a Microsoft Exchange Server mailbox | Works with Exchange, POP, and IMAP accounts |
You can now send professional, context-aware messages while you are away. Test your setup by asking a colleague and an external contact to send you a test email. For more advanced control, explore creating rules that reply only to emails marked with High Importance or that come from specific security groups.
