How to Fix Automatic Replies Not Working with IMAP in Outlook 365

Product: Microsoft Outlook 365
Device & OS: not provided
Scenario: Attempting to remove an outdated Out of Office reply and set up a new automatic reply for an IMAP account.
Observed behavior: Native automatic replies are unsupported for IMAP accounts in Outlook, and an old auto-reply continues to send because Outlook cannot overwrite the server-side configuration.

Before you start

Verify who your email hosting provider is (e.g., Gmail, Yahoo, or a custom host) and ensure you have your webmail login credentials, as you will need server access to remove old replies.

Solution 1Recommended

Remove the Old Automatic Reply via Webmail

Because Outlook cannot control server-side settings for IMAP accounts, you must log into your email provider's web interface to delete the old auto-reply.

Automatic replies created in older setups or on the server side are stored directly by your email provider. Outlook 365 syncing via IMAP cannot override, view, or delete these server-level configurations.

Access your webmail

Open a web browser and navigate to your email provider's webmail login page (such as Gmail.com, Yahoo Mail, or your company's custom webmail portal).

Log in to your account

Enter your IMAP email address and password to access your mailbox directly on the server.

Locate email settings

Click on the Settings gear icon, usually located in the top-right corner of the webmail interface.

Disable the auto-reply

Look for a menu named 'Automatic Replies', 'Vacation Responder', or 'Out of Office'. Turn off the active reply and click Save Changes.

Remove the Old Automatic Reply via Webmail

Server-side changes apply immediately: Once disabled in your webmail, the old automatic reply will immediately stop sending to incoming emails.

Solution 2

Set Up a Client-Side Rule for IMAP Auto-Replies

Create a custom rule within Outlook to automatically reply to incoming messages. This bypasses the lack of native Exchange auto-reply support for IMAP.

Frequently Asked Questions

Why is the Automatic Replies (Out of Office) button missing in Outlook?

The native Automatic Replies feature in Outlook is exclusively designed for Exchange server accounts. If you are using an IMAP or POP3 account, the button will be hidden from the File menu.

Can I set up an Out of Office reply for IMAP without leaving Outlook open?

No, you cannot do this through the Outlook desktop client. To send auto-replies while your computer is off, you must configure the vacation responder directly on your email provider's webmail interface.

Will upgrading to Microsoft 365 fix my IMAP auto-reply issues?

No, upgrading your version of Outlook will not change how IMAP accounts handle automatic replies. The limitation is inherent to the IMAP protocol itself, not the specific version of Microsoft Office you are using.
