How to disable email addresses in reply headers


Email Alias Manager for Exchange allows you to choose which email address to use for sending (and receiving replies to) emails, at the point you send the message. Instead of managing multiple POP3 accounts, you define all required aliases to be available for a single mailbox. When sending an email, you choose which alias to use and recipients will see that alias name displayed in the message from field.

However, with standard registry settings, when a recipient chooses to 'reply' to a message, reply headers will show a display name followed by the originating email address in reply headers. For example:

Display name with email address.

As such, you may prefer to disable the email address in reply headers. In this case, the same example would look like this:

Display name with no email address shown.

The Process

To disable the email address in reply headers, you need to update the Windows registry for any computers using the Email Alias Manager Outlook Add-in. If you are not familiar with the Windows registry, you may wish to read about the Windows registry before attempting any changes.

Windows Registry modifications should always be approached with extreme care - serious problems might occur if you modify the Windows registry incorrectly.

We strongly advise you to back up the Windows registry before any modifications are made - in doing so you will have the option to restore the backup if a problem occurs.
