How to Exclude Specific Senders from Shared Mailbox Automatic Replies
Question details
The user wants to keep automatic replies active for a shared mailbox but needs to prevent specific senders from receiving these automated responses.

- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Managing out-of-office or general automatic replies for a shared team mailbox without sending them to certain addresses.
- Observed behavior
- The user needs the auto-reply rule to operate at the server level so it stays active continuously, while silently bypassing selected senders.
Ensure you have 'Full Access' permissions to manage settings and rules for the shared mailbox before attempting to configure server-level automatic replies.
Configure Server-Level Automatic Reply Rules in Outlook
Set up an advanced rule within the Automatic Replies menu to explicitly exclude designated senders from receiving the automated response.
To ensure that your shared mailbox processes replies 24/7 without needing the Outlook client to remain open, the rule must be configured at the mailbox or server level using the Automatic Replies feature, rather than relying on a local Outlook rule.
In your Outlook desktop client, click on the 'File' tab in the top-left corner, go to 'Info', and select the 'Automatic Replies' button.
Select the 'Send automatic replies' radio button to enable the feature. Then, click the 'Rules...' button located in the bottom-left corner of the dialog box.
Click 'Add Rule...'. In the conditions section, specify the email addresses or domains of the senders you want to exclude in the 'From' field.
Check the advanced options to apply the rule only to items that do not match the sender conditions, and then configure your auto-reply template in the action section.
Click 'OK' to save your rule. It is highly recommended to send test emails from both an excluded address and a standard address to confirm the rule functions correctly.

Frequently Asked Questions
Why shouldn't I use a standard local Outlook rule for this?
Standard local rules only run when the Outlook desktop application is open and actively running on your computer. Server-level rules configured via the Automatic Replies menu ensure the shared mailbox processes emails 24/7 regardless of your device's status.
Can I exclude an entire domain instead of individual email addresses?
Yes. When specifying the senders to exclude in the rule conditions, you can enter the domain name (e.g., @company.com) to prevent automatic replies from being sent to anyone within that organization.
Do I need special permissions to configure rules for a shared mailbox?
Yes, your user account must be granted 'Full Access' permissions to the shared mailbox by your IT administrator to open its settings and modify server-level automatic reply rules.
