If you’re facing the issue of Outlook Auto Reply Not Working, it can disrupt important communication, especially when you depend on automatic responses for out-of-office notifications or client updates. Many users specifically search for solutions to Outlook Auto Reply Not Working when their automatic replies fail to send internally or externally. This problem can occur for several reasons. Sometimes Automatic Replies are not properly enabled, the selected date and time range has expired, or responses to external senders are disabled. In other cases, conflicting mailbox rules may override the auto-reply feature without displaying a clear error. For Microsoft 365 or Exchange accounts, synchronization issues, mailbox storage limits, or administrative restrictions can also prevent automatic replies from functioning correctly.


Another commonly overlooked cause is corruption within Outlook’s PST or OST data files. Even if all settings appear correct, damaged data files can silently interfere with features like automatic replies. Basic troubleshooting steps such as restarting Outlook, updating the application, or recreating the user profile may help resolve minor glitches. However, if the issue persists, using a professional repair tool like Cigati Outlook Email Recovery can scan and repair corrupted Outlook files to restore proper functionality.
