Remove AutoComplete list entries one at a time

Remove AutoComplete list entries one at a time

The AutoComplete list, or nickname cache, is automatically generated when you send emails from Outlook. It includes SMTP addresses, LegacyExchangeDN entries, and display names of previous recipients. If an email address changes, the cache does not update automatically. You need to remove the old cached address before entering the new one.

Follow these steps to remove an AutoComplete entry:

1. Open a new email message.
2. Type the first few characters of the AutoComplete entry that you want to remove.
3. When the entry appears in the list of suggestions, move your mouse pointer over the suggestion until it becomes highlighted, but don't select it.
4. When the X icon appears next to the highlighted suggestion, select X to remove the entry from the list, or press the Delete key on the keyboard.

Selecting X will prevent that name entry from appearing in the AutoComplete list again but won't remove it from your account. This entry may still appear in other areas in Outlook (such as search boxes).

Note: If you send a person a new email after you've removed their name from the AutoComplete list, their information will be restored to the list.
