How to Turn Off an Old Auto-Reply on an IMAP Account in Outlook
Question details
The user needs to disable a persistent automatic reply on an IMAP email account, especially after upgrading to Microsoft 365.

- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Upgrading from an IMAP email account to Microsoft 365 and encountering an active, outdated auto-reply that continues to send.
- Observed behavior
- An old automatic reply continues to send responses to incoming messages even though it appears inactive in the current email client settings.
Ensure you have the login credentials for your original email provider's webmail interface, as IMAP auto-replies are most commonly handled on the server side rather than in the local email client.
Disable the Auto-Reply via the Email Provider's Server Control Panel
Use this method to stop auto-replies that are processed directly on your email provider's server, which is the most common cause for IMAP accounts.
IMAP accounts do not synchronize out-of-office settings with Outlook natively. If an auto-reply is still active after migrating or updating your software, it is almost certainly running on the web server of your email host.
Open a web browser and sign in to the webmail interface or server control panel provided by your original email hosting provider.
Look for a 'Settings', 'Preferences', or 'Gear' icon, typically located in the upper right corner of the webmail interface.
Find the section labeled 'Auto-Responder', 'Vacation Message', or 'Out of Office'. Toggle the setting to the 'Off' position and save your changes.

Check Outlook Automatic Replies and Rules Settings
Verify that no local Outlook rules or leftover Exchange settings are triggering the automatic reply.
Recreate Your Outlook Profile
If the auto-reply persists due to corrupted local configurations after migrating to Microsoft 365, recreate your Outlook profile.

Frequently Asked Questions
Why does my IMAP auto-reply still send after migrating to Microsoft 365?
The auto-reply is likely still configured directly on your legacy email provider's server. Because IMAP only syncs emails and not server configurations like auto-responders, you must log into your old provider's webmail interface to disable it.
Where are the Automatic Replies settings located in Outlook?
In Outlook, click the 'File' tab in the top-left corner. The 'Automatic Replies (Out of Office)' button will be visible there. Note that for standard IMAP accounts, this native button may be missing, requiring you to use rules instead.
Can an Outlook rule send an automatic reply?
Yes. Users often set up custom rules in Outlook to reply to incoming messages when native Out of Office features aren't available. You can view, disable, or delete these by going to File > Manage Rules & Alerts.
