Office 365 - Remove Addresses From the Auto-Complete List

Many clients have the ability to remember what addresses you have sent messages to, this is known as your auto-complete list. Sometimes you may enter the wrong address for a recipient or the recipient changes their address. The steps below will guide you through the process of either removing an address from this list or clearing the entire list.

Note: If you are experiencing an error indicating that no match is found or that the message cannot be sent because one of the addresses is invalid, clearing your Auto-Complete list could solve the issue.
