We’ve had a few people complain that Outlook’s signature switching feature broken so I figured it was time for a refresher course on how it works.

If you are using Outlook 2003 with Word as your editor or Outlook 2007 and have multiple accounts, you can assign a signature to each account and Outlook will change signatures when you select the non-default account.

However – and this is important – you must assign a signature to the default account and should assign signatures to each secondary account. If a signature is not assigned to an account the capability to swap signatures is removed from the message when that account is selected. It won’t be restored when you switch to an account that has a signature assigned.

If you don’t want a signature on an account, create a blank signature that contains just two dashes ( -- ) so you can see where the signature begins.
