Help! My Outlook Auto Replies not working

I have a customer who terminated an employee today. They asked me to delete the employee's email address, create an alias for that employee, and forward it to another email box.

I have done this with no problem. The next step was to set up an auto-reply in the mailbox to let senders know to update their address box to reflect the change. But cannot get this to work.

Currently, I am working with the Outlook 2016 client on a desktop and have tried the following triggers with specific words in the recipient's address and used the complete email address and just the user name before the @ @where my name is not in the To box from people or a public group Email server is Exchange in Office 365 I have looked a the web client and it has less to offer. Any ideas?

Solution 3. Filter the junk emails out of automatic replies

In Outlook, the Junk Email folder stores suspected spam messages instead of blocking them. This folder, with the Junk Email Filter, is saved on the Server and can be accessed from any device.

Also, the out-of-office message is automated and may be caught by Junk Email Filters. These messages now appear in the Junk Email Folder after being filtered, and users can find them in the server's Junk folder.

In simple terms, this choice stops auto-replies from reaching email addresses not present in the organization's exchange setup. To allow replies outside the organization, the admin should adjust the automatic reply settings.

Mark the box for automatically replying to individuals outside my organization. By making these changes, Outlook Automatic Reply will be able to respond to people who aren't part of the organization.

Tick Auto Reply to People Outside My Organization

Solution 5. Fix the Outlook Automatic Replies once per address

By default, the assistant's response is limited to once per address. Yet, there are instances when users need to resend messages to all addresses. In such cases, the user should toggle OFF the out-of-office features and then toggle them ON again.

Moreover, server-side rules permit users to reply to each received message. Hence, the end user should engage the Exchange administrator to address this concern.

Toggle out of Office
