Clearing Contacts from the Cache Memory

Outlook comes with an Autocomplete List feature that keeps a record of every email id you have ever contacted, whether recently or at a previous point in time. All these data are accumulated in the cache of your Outlook application.

Now, in order to clear contacts from the cache memory, you can opt for two different methods for two different scenarios. Suppose you want to remove only some specific email addresses, then you have to do it manually by deleting the suggestions from the Autocomplete Kist. And, if you want to clear the whole cache data, you just have to clear the Autocomplete List.

Clearing individual contacts from Autocomplete List:

  1. Launch Outlook, and compose a new email.
  2. In the destination address (To) text box, type the initial letters of the email id you want to remove. As you type the letters, the autocomplete list will throw suggestions as available matches. Scroll down to select the contact that is intended to be removed and click on the ‘X’ (Delete) button adjacent to the suggestion.
  3. Clearing individual contacts

Clearing the entire Autocomplete List:

  1. Launch Outlook and navigate through File >> Options.
  2. In the Outlook Options window, select the Mail tab and click on the Empty Auto-complete List button from the Send messages section.
  3. Empty Auto-complete List
  4. Confirm clearing the entire Autocomplete List, click the Yes button.
  5. Confirm clearing
  6. You can also disable the Auto-complete List feature if you don’t want your Outlook program to store any key-events or suggestions in the future. Just uncheck the Use Auto-complete List to suggest names when typing in the To, Cc, and Bcc lines checkbox.
  7. disable the Auto-complete List feature

All addresses from the Autocomplete List and the cache memory are cleared by now.

There are some rare cases where the user is unable to delete contacts from the suggestion list while composing emails. This happens because of unexpected errors like corruption or damages to the PST.
